Study On Evaluation Index System And Evaluation Model Of Cultivated Land Resource Distribution And Utilization

Cultivated land resources is one of the important components of surface natural resources.It is of great significance to study the distribution and utilization of cultivated land resources in the region.Based on the geography and national conditions census data,the socio-economic and other thematic data,supplemented by the application of statistical analysis and GIS analysis techniques to build arable land resources index system and model method research,the Objective evaluation of the spatial distribution of cultivated land resources and the degree of resource utilization,and provide the basis for government decision-making and planning.And provide the theoretical basis for constructing the framework of the distribution and utilization index system of natural resources.Based on the study of predator land resources evaluation,this paper constructs the index system of distribution and utilization of cultivated land resources from the three dimensions of resource endowment,resource distribution and resource utilization,and clarifies the relationship between cultivated land resources distribution and utilization in the evaluation of cultivated resources weight determination method,and the evaluation model based on the comprehensive index method.In order to verify the scientific rationality of the evaluation model,this paper conducts an empirical study on 51 townships in Dehong,and analyzes the results of the index and corresponding indicators.The results are in line with the distribution and utilization of cultivated land resources in the experimental area,Distribution and utilization of evaluation index system and the scientific rationality of the evaluation model,lay the foundation for the study of resource distribution and utilization.
