Description

A kind of high standard capital farmland construction Project Areas preferably automatedization computational methods
Technical field
The present invention relates to a kind of high standard capital farmland construction Project Areas preferably automatedization computational methods, category farmland design rule Draw technical field.
Background technology
With《High standard capital farmland construction standard》(TD/T 1033-2012)Issuing and implementation.At present in high standard The aspects such as the suitability evaluation and Location Selection of Construction Project of capital farmland construction project have been carried out correlational study, but whole evaluation , from assessment indicator system foundation, model construction, suitability classification up to Project Areas addressing, whole calculating process is very multiple for process It is miscellaneous, but at this stage, the research in terms of China's high standard capital farmland construction is the calculating work by the use of ArcGIS as auxiliary Tool, inreal is combined with GIS-Geographic Information System, and evaluation procedure is extremely loaded down with trivial details, therefore, for the person that reduces related work Working strength, improve the scientific and reasonability of high standard capital farmland construction project site selection, high standard basic farmland item The research that preferred automatization of mesh area obtains is imperative.
At this stage, to high standard capital farmland construction suitability evaluation often by manually setting up high standard basic farmland Build suitability evaluation index system and the weight of determination evaluation index is calculated by artificial combination.Using Arcgis and Excel forms build comprehensive index assessment model and high standard capital farmland construction suitability are evaluated, and by high standard base This farmland construction suitability is divided into that height is suitable, moderate is suitable, it is low it is suitable, be not suitable for four grades.
To the estimation of stability in high standard basic farmland space often by manually setting up high standard capital farmland construction Spatial stability assessment indicator system, determines the weight of evaluation index using Subjective-objective Combination enabling legislation.Mould is evaluated by building Type is to manually utilizing computer software, man-machine interaction to be evaluated, and passes through Arcgis by high standard capital farmland construction space Stability is divided into that highly stable, moderate is stable, low stable and unstable four grades.
High standard capital farmland construction Project Areas optimization model is by building coupling degree model, using for reference conventional coupling Close degrees of coordination judgment criteria, determine high standard capital farmland construction complexity, i.e., possess substantially, slightly transform, renovating comprehensively, It is not suitable for building.And at this stage, often through manually being carried out using computer, basis after multiple computing is final to be counted the structure of model Calculate result and determine its coupling degree, then classification is manually combined by Arcgis and excel to which on this basis and is returned Class collects, and determines high standard capital farmland construction complexity finally according to its summarized results.
The content of the invention
The invention aims to provide a kind of high standard capital farmland construction Project Areas preferably automatedization computational methods.
To reach above-mentioned purpose, the present invention is implemented according to technical scheme below:
A kind of high standard capital farmland construction Project Areas preferably automatedization computational methods, comprise the steps:
The first step, builds optimization evaluating system, constructs in computer systems first excellent for capital farmland construction Project Areas Select the automation data arithmetic system stand-by of automatization's evaluation and test;
Second step, raw data acquisition, it is first determined farmland item area to be evaluated, then respectively by on-site data gathering, Government administration section data of literatures and survey region Land_use change change data, survey region land control planning and its number According to storehouse, survey region dem data, survey region overall plan for land use and its data base, survey region Farmland Grading into Really, each relevant evaluation meter in the range of farmland item area to be evaluated is obtained in terms of second soil survey information of survey region three Supplemental characteristic is calculated, in the optimization evaluating system that then Various types of data for collecting is separately input to constructed by the first step, and root Classification storage is carried out to each data of typing according to data type;
3rd step, project appraisal classification, the relevant evaluation of the farmland item area to be evaluated being entered into according to second step in system Calculating parameter data, calculate ginseng to the relevant evaluation of farmland item area to be evaluated using the optimization evaluating system that the first step builds Number data carry out calculation process, and realization carries out Adaptability Evaluation and estimation of stability operation to farmland item area to be evaluated, its During middle Adaptability Evaluation, two are carried out to the farmland item area to be evaluated determined in the first step according to administration cell and ground class unit Level is divided, wherein class dividing elements when, according to being divided for basic farmland institute possession class;
4th step, high standard basic farmland Project Areas optimization classification, according to the mutual evaluating data that the 3rd step computing draws, to ginseng With the projects evaluated successively according to coupling degree, couple develop in harmony type and high standard capital farmland construction complexity Evaluated and tested, and finally drawn high standard basic farmland Project Areas optimization classification concrete outcome.
