The embodiment of the invention provides a tourism resource evaluation method based on GIS gridding fitting analysis, and FIG. 1 is a flow chart of the evaluation method according to the embodiment of the invention, as shown in FIG. 1, the method comprises the following steps:

step S101, determining at least one of the following travel resource evaluation types: developing potential grid evaluation, tourism traffic zone grid evaluation, tourist data space grid evaluation, tourism economic industry development level grid evaluation and tourism resource restriction factor grid evaluation;

step S102, determining a plurality of grade indexes contained in the evaluation type of the tourism resource;

step S103, acquiring a tourism resource data object corresponding to the tourism resource evaluation type in a preset area, and setting the tourism resource data object in a GIS according to a preset mode;

and S109, obtaining an evaluation conclusion according to the fitting analysis result and the grade index distribution condition.

It should be noted that, because the types of the data objects of the tourism resources are various, the contents of the tourism resources to be evaluated are also various, and therefore, the adopted tourism resource evaluation type needs to be determined according to the actual needs, in the embodiment of the present invention, the following commonly used tourism resource evaluation types are listed: development potential grid evaluation, tourism traffic zone grid evaluation, tourist data space grid evaluation, tourism economic industry development level grid evaluation and tourism resource restriction factor grid evaluation, and it should be understood that embodiments obtained by adopting other tourism resource evaluation types without creative labor by ordinary technicians in the field all belong to the protection scope of the invention.

In step S105, fitting and analyzing the gridded data by using at least two fitting methods, so as to compare the fitting and analyzing results obtained by the at least two fitting methods, and obtain an analysis conclusion of the optimal fitting method.

It should be noted that, in the fitting method adopted in the embodiment of the present invention, the global polynomial GPI fitting method solves the predicted value through a polynomial according to the value of the total tourist resource point in the research area; the local polynomial LPI fitting method is also a non-exact fitting model, which uses several polynomials located in the neighborhood of a specific overlap to construct a smooth surface.

The inverse distance weight IDW fitting method is based on the similar similarity principle and carries out weighted average by taking the distance between the fitting point and the observation point of the tourist resource as the weight. The specific formula is as follows:

in the formula:

is the target interpolation; z (x)_i,y_i) Is the observed value of the tourism resource of the ith grid center; d_iThe distance from the ith tourist resource observation value to the interpolation point; lambda [ alpha ]Representing the weight, the closer the travel resource observation value is to the interpolation point, the higher the weight is.

The RBF fitting method is composed of functions of single variables and is suitable for fitting operation of a large amount of tourist resource point data. In GIS, the RBF typically includes different basis functions such as a tension spline function, a regular spline function, a higher order surface function, and the like.

wherein, the fitting condition is satisfied:

s(X_j)＝f_j；

In the fitting method adopted by the embodiment of the invention, the Kriging fitting method is based on the geostatistics of a variation function theory basis as a core, the unbiased optimal estimation of the regional variables in a specific range is realized, and the characteristics of the spatial position, the size, the shape and the like estimated by an observed value are considered. Epsilon is usually reflected by a half-variance function r (h)₁How much(s) a semi-variogram is a singly increasing function of h, i.e. the closer the distance is to its nullThe smaller the inter-variability, the formula is as follows: z(s) ═ m(s) + γ (h) + ε₂。

In the formula: z(s) is an interpolated value; m(s) represents the spatial trend change of the observed value of the tourism resource; epsilon₁(s) represents a variant; epsilon₂Representing a residual error term; and s is the spatial positioning of the observed value of the tourism resource. The formula for r (h) is:

N(h)＝{(s_i,s_j):s_i-s_j＝h；i,j＝1,2,…,n}

in the formula: and N (h) point pair sets representing the observed value evaluation results of the tourism resources. N is the total number of observations; the semivariogram primarily determines the weighting factor lambda_i. As in ordinary kriging, the spatial position s is assumed₀Is a linear combination of observed values:

under the condition of minimum mean square error of the predicted value, the following objective equation can be obtained:

in the formula: m is a Lagrange multiplication constant, and further,

further can obtain

Respectively to lambda_i(i is 1,2, …, n) and m, and the resulting partial derivatives are made 0, and the parameter values obtained are as follows:

m＝-(1-1Γ^-1r)/(1Γ^-11)

where λ' ═ λ (λ)₁,λ₂,...,λ_n),r＝(r(s₀-s₁),r(s₀-s₂),…,r(s₀-s_n) ') and Γ is an n × n matrix.

Different types of kriging fitting methods are determined for m(s), r (h), λ, etc. in 3 aspects. Wherein m(s) in Ordinary Kriging (OK) is unknown constant,

simple Kriging (SK), m(s) being a known constant, λ being unlimited; the basic assumption of the Universal Kriging (UK) fitting model is E (m (s)) u(s),

it should be noted that, the travel resource data object is to obtain the relevant data corresponding to the travel resource evaluation type in the predetermined area according to the actual need of the travel resource evaluation type, including but not limited to: the system comprises classified tourism resource single space data, administrative region space data, traffic space data, water system space data, data related to statistical yearbook, statistical data of tourist number and natural disaster statistical data.

Meanwhile, the travel resource data object is set in a GIS according to a predetermined manner, taking the Qingdao city as an example, fig. 2 is a schematic diagram of spatial data of a classified travel resource monomer in the Qingdao city provided by an embodiment of the present invention, and fig. 3 is a schematic diagram of spatial data of a classified travel resource monomer in the Qingdao city provided by an embodiment of the present invention.

As shown in fig. 2, in the present embodiment, 3661 total tourism resource units in the Qingdao city tourism resource data objects are collected, wherein the total number of the natural tourism resource units is 1140, which accounts for 31.14% of the total number of the units, the total number of the human tourism resource units is 2521, which accounts for 68.86% of the total number of the units, the tourism resource data objects are specifically divided into eight types, namely, a geographical landscape, a water scene, a biological landscape, an astronomical and climatic landscape, an ruined site and vestige, a building and a facility, a tourism commodity and a human activity, and the tourism resource data objects are set in a GIS according to a predetermined manner; as shown in fig. 3, the total number of the first-level, second-level, third-level, fourth-level and fifth-level human tourism resource monomers in the whole city is 497, 412, 186, 41 and 4 respectively, and each of the monomers accounts for 43.60%, 36.14%, 16.31%, 3.60% and 0.35% of the total number of the tourism resources, the tourism resource data object is specifically divided into the first-level to fifth-level tourism resource monomers, and the tourism resource data object is set in the GIS according to a predetermined manner.

Preferably, the tourism resource evaluation type adopting development potential grid evaluation is determined.

Taking Qingdao city as an example, fig. 4, 5 and 6 are schematic diagrams of a GIS tourism resource development potential gridding model respectively adopting scales of 0.5km, 1km and 2km provided by the embodiment of the present invention, which will be described in detail below:

as shown in FIG. 4, FIG. 5 and FIG. 6, an improved model of the development potential of the tourist resource group is selected, and the simulation is performed by using the tourism resource gridding with the scale of 0.5km, 1km and 2km respectively. Determining a plurality of grade indexes to be a special-grade tourism resource group, a good-grade tourism resource group, a medium-grade tourism resource group, a secondary tourism resource group and a poor-grade tourism resource group in sequence, weakening the development potential in sequence, and respectively performing fitting analysis on the gridding data by adopting the following five fitting methods: global polynomial GPI fitting method, local polynomial LPI fitting method, inverse distance weight IDW fitting method, radial basis function RBF fitting method, Kriging fitting method.

The radial basis function RBF fitting method comprises the following three models: the method comprises a tension spline function (SWT) model, a regular spline function (CRS) model and a high-order surface function (MF) model, wherein the Kriging fitting method comprises the following two models: common kriging (OK) models, Simple Kriging (SK) models.

Wherein, the RBF-based tension spline function, the regular spline function, the higher-order surface function and the simple Krigin function are selected under the scale of 0.5km grid and are mainly considered in the research, and the RBF-based tension spline function, the regular spline function and the simple Krigin function are selected under the scale of 1km grid and are mainly considered in the research; local polynomial fitting models, tension spline functions and high-order surface function fitting are selected under the 2km grid scale and are considered in key during research, and the local polynomial fitting models, the tension spline functions and the high-order surface function fitting are shown in table 1:

TABLE 1

In summary, the following evaluation conclusions are drawn: the tourism resource development potential results obtained by different gridding methods on the same scale have certain difference, and the gridding results of different scales have different spatial characteristics: the grid of 0.5km scale is fine, the calculation result is smooth in spatial display, the grid granularity is obvious, and the tourism resources have obvious north-south difference in the overall layout; after the scale of 1km is increased, the spatial distribution condition of the development potential of the tourism resources can be obviously expressed, which shows that the tourism hotspots in Qingdao cities are excessively concentrated in Laoshan, coastal areas and other mature long and narrow areas, the tourism development space is lack of depth, and the tourism resources in inland areas are not effectively developed; the 2km scale shows the spatial distribution of the development potential of the tourism resources more thickly, the grid particles are distributed more obviously, and more obvious special-grade and excellent-grade tourism resource groups appear in main urban areas, namely Laoshan mountain and Daze mountain.

Preferably, the tourism resource evaluation type of the grid-based evaluation of the tourism traffic area is determined.

Taking Qingdao city as an example, fig. 7 is a schematic diagram of a grid networking model of a GIS tourist resource tourist traffic area respectively adopting scales of 0.5km, 1km and 2km, which is provided by an embodiment of the present invention and will be described in detail below:

as shown in fig. 7, the main road data of the Qingdao city is selected, and the gridding accessibility under the multi-level scale is directly constructed by combining the road network density model of each region city. The five grade indexes for determining the tourism resource evaluation type comprise an excellent traffic zone, a general traffic zone, a poor traffic zone and a poor traffic zone.

Analysis shows that under the scale of 0.5km, the northern part of the glue bay of the Qingdao road is obviously distributed in an inverted region shape and is diffused along the administrative center of each row in a point-axis mode, the southern part of the road is mainly distributed along the sea, 11 routes such as Jinqing high speed, Huanjiao high speed, Shunkong high speed and Qinglai high speed are successively established in the whole city, wherein the glue bay tunnel and the cross-sea bridge form a link of 'blue and yellow connection', and the time is greatly shortened for the Qingdao travel. Under the scale of 1km, the areas with the highest highway density are concentrated in the gulf of Oncao and the developed economic areas in the north; the reachability measurement patterns of the city of flatness and the city of leisy show remarkable high-speed pointing characteristics. Under the scale of the 2km grid, the accessibility level of the west coast and the north of the southwest Qingdao region, which mainly comprise the south China jiao city, to the Lai West region is gradually reduced by taking the urban region as a core region.

Preferably, the tourism resource evaluation type of the tourism resource evaluation by adopting the tourism data spatial grid evaluation is determined.

Taking Qingdao city as an example, fig. 8 is a schematic diagram of a spatial grid model of GIS tourists data respectively adopting scales of 0.5km, 1km and 2km provided by an embodiment of the present invention, which will be described in detail below:

as shown in fig. 8, several grade indexes for determining the evaluation type of the tourist resources are divided into five grades according to the clustering degree of tourists in the whole market: the tourist high collecting area, the tourist medium collecting area, the tourist general collecting area and the tourist rare area.

Wherein, the distribution of tourists is integrated by the factors of tourism resources, supporting facilities, traffic areas and the likeInfluence, initial selection of Tourism resource development potential (DX)₁) Distance between main and urban areas (DX)₂) Distance to trunk (DX)₃) Star hotel Distance (DX)₄) POI center Distance (DX) in travel industry₅) Distance of population concentration area (DX)₆) And 6 influence factors are used as the spatial grid simulation of the tourist data. Table 2 is a GWR model fitting result table, and after the sample data is respectively standardized, a GWR model of the Qingdao city tourist data is constructed, and the adjustment type spatial kernel regression and the AICc method are selected to analyze and simulate the Qingdao city tourist data. The minimum value of the AICc is obtained by calculation when the number of adjacent points is 55. R²Is 0.8651, correcting for R²The value of (d) is 0.7981, and the fitting effect is better at this time, as shown in table 2:

residual value (Residual)	Sigma	AICc	R²	Correcting for R²	Sum of squares of residuals
						0.3221	0.1409	-47.8363	0.8651	0.7981	0.9528

And the table 3 is a GWR model estimation result table, and data such as the average value, the minimum value, the maximum value, the standard deviation, the lower quartile, the upper quartile and the like of the influence degree of each factor on the tourist data distribution are obtained through GWR model estimation. The development potential of the tourism resource shows a remarkable influence, which shows that the larger the development potential of the tourism resource is, the more tourists are; distance between main and urban areas (DX)₂) The average value and the median of the index influence regression coefficient are positive numbers, namely, the number of tourists is improved along with the increase of the distance of tourist resources along with the main urban area; distance to trunk (DX)₃) The average value of the index influence regression coefficient is also positive, but from the Qingdao city, the influence of the traffic zone on the tourist distribution is low, mainly because the Qingdao city is convenient to traffic and famous scenic spots can be reached smoothly; while the star hotel>Population gathering area>The average coefficients of the tourism industry are negative values, which indicates that various facilities have positive promotion effect on the distribution of tourists, and are shown in table 3:

TABLE 3

And substituting the coefficient index value obtained by GWR analysis into a tourist data gridding model in Qingdao city to further obtain the spatial distribution pattern of tourists in the whole city, wherein five grades of the clustering degree of the tourists in the whole city are obtained, a large number of tourists are intensively distributed in the main city area and radiate to the north, and the clustering characteristics are shown in a central point manner in other areas such as flatness and south China along the east part of the coastline and the second place of the gulf in Jiaozhou.

Preferably, the grid evaluation type of the tourism economy industry development level is determined.

Taking Qingdao city as an example, fig. 9 is a schematic diagram of a grid model of the GIS tourism economic industry development level respectively adopting scales of 0.5km, 1km and 2km provided by the embodiment of the present invention, which will be described in detail below:

In the specific implementation process, the tourism status of each district city of Qingdao is selected, indexes such as A-level scenic spots, hotels above 3 star level, travel agencies, star-level restaurants, golf courses, tourist shopping malls and the like are selected, longitude and latitude coordinates of various POI are obtained through a network map API, and the development level of the tourism industry in each grid unit is analyzed. By measuring and calculating the space density of the tourism industry in each level of scale grid unit, the tourism industry has radiation effect on the periphery of the tourism industry within a certain range, so that the final result is subjected to fitting analysis by multiple models such as IDW, GPI, LPI, SWT, CRS, MF, OK, SK and the like, and the simulation result is shown in FIG. 9.

According to the analysis results of the embodiment, the local polynomial fitting and the common kriging fitting under the 0.5km grid scale have the best effect, the average prediction errors are-0.151 and 0.054 respectively, and the root mean square prediction errors are 3.172 and 7.391 respectively; the high-order surface function, the ordinary kriging method and the simple kriging fitting method are selected under the scale of 1km grid and are mainly considered in research, the average prediction errors are respectively 0.220, 0.021 and 0.223, and the root-mean-square prediction errors are respectively 8.280, 7.391 and 2.836; the fitting effect of the high-order surface function and the local polynomial fitting model is optimal under the 2km grid scale, the average prediction errors are respectively 0.659-0.200, the root mean square prediction errors are respectively 15.004 and 13.705, and table 4 is an error analysis result table:

TABLE 4

Through the analysis of the embodiment, the core distribution of the tourism industry can be more prominent under the scale of 0.5km grid which is sporadically distributed in the gulf of the islands of the national islands, the coastal areas of the eastern China and the urban areas, which also shows that the areas with higher development level of the tourism industry are highly related to the developed degree of urban economy, and the development of the tourism industry can be directly influenced by the quality of the economic development; the distribution range under the scale of 1km is distributed in Qingdao urban areas and important tourism areas, so that the tourism status of the Qingdao urban tourism industry is continuously improved along with the high-speed development of economy; the areas around the tourist industry gathering place under the 2km scale are mostly tourist resource gathering places, such as the old ink wine house, the Guzhou culture street, the Laxi Xisha ancient ruins, the plum blossom mountain ecological sightseeing garden and the like, which shows that the Qingdao tourist industry benefits from the good urban environment.
