Based on second national land investigation figure spot data, according to the administrative division of land resource Task and region, obtain survey region figure spot data.
2, Task business form is generated
Researchist, by the analysis to Task, specifies the key element index that related tasks research institute needs, and by index assignment method, gives each corresponding diagram spot, to form the business form data about Task by different for survey region key element desired value.
Task business form is a dynamic list, and it constantly can change, until all key element indexs can meet the needs of related tasks research for the adjustment of key element index along with related tasks research.
3, empirical model (utilizing soil business experience model calculation formula) is set up
Based on man-machine interaction environment, with land-use map spot for basic computational ele-ment, for studying a question, application experience knowledge, based on " soil business experience model calculation formula ", gives weight to key element index, and the calculated relationship set between key element index, thus set up empirical model.
(1) key element index weights is arranged
Study of Land Resources research must relate to multiple key element index, and the influence power changed land resource due to different key element index is different, and the influence power otherness between each index is measured by weight.Therefore, indicator of distribution weight scientifically and rationally, significant to the calculating of Study of Land Resources key element index.
Researchist is by " soil business experience model calculation formula " autonomous selective goal and carry out weight setting to it, to determine the contribution margin of each index to result of calculation.
(2) key element index calculate relation setting
Calculated relationship between key element index comprise add, subtract, multiplication and division, also higher mathematics computing function is comprised, researchist sets the mathematical computations array mode between each index by " soil business experience model calculation formula " from main separation, calculates with the empirical modeling realized for land resource comprehensive monitoring data.
4, survey region figure spot result of calculation is analyzed
Calculated relationship between key element index, once determining, namely obtains areal map spot result of calculation by " soil business experience model calculation formula ".Playing up by carrying out classification to result of calculation, the result figure of related tasks research can be generated.By field investigation or the comparative studies with existing correlative study achievement, error analysis is carried out to result of calculation figure, find and find in result figure, to calculate incorrect or that error is larger place, then by for the repeatedly feedback regulation of result of calculation, calculating, till acquisition is satisfied with result of calculation.
5, result of calculation feedback regulation
Through on-site inspection or after being analyzed with existing achievement in research, if find, result of calculation is not well positioned to meet the object of Task, by carrying out repeatedly feedback regulation, calculating to result of calculation, to obtain more accurately, result of calculation clearly.As shown in Figure 1, the feedback regulation mode of result of calculation comprises adjustment key element index, adjusts weight, resets calculated relationship.
(1) key element index is adjusted
Study of Land Resources research relates to the many factors such as climate condition, hydrologic(al) regime, geology and geomorphology, vegetative coverage situation, biological condition, environmental situation, and, natural, economy, the social condition that have due to different survey regions are not quite similar, what it faced study a question and different, is therefore also not quite similar to the influential index of these problems.For the Task in a certain concrete region, the key element index selected by experience and accept or reject, may be needed by repeatedly repeatedly adjusting, or increases or reduce key element index, until form representative the strongest index system, to meet the Study on Problems of domain of dependence.
(2) weight is adjusted
The weight of key element index is directly connected to the correct degree of final analysis result.A certain key element index on Study of Land Resources to research and analyse impact large or important, then the weight of this index is just large.In real work, mainly determined according to the subjective experience of operating personnel for the determination about key element index weights.If the analysis results completed in key element index weights determination situation is not accurate enough, can attempt by adjustment indices weight, to obtain analysis result more accurately.
(3) calculated relationship is reseted
Mathematical calculating relations between each index has very important impact to final Comprehensive analysis results.How by accurately setting up mathematical calculating relations to realize for relevant Task accurate analysis between the index determining weight, due to the complicacy of Land, continuous repeated attempt is usually needed to set up mathematical calculating relations between indices, to obtain the ideal relevant experience expression model studied a question.
