Method for evaluating performance of cultivated land requisition-compensation balance based on PSR model

Abstract

The invention discloses a method for evaluating the performance of cultivated land requisition-compensation balance based on a PSR model. The method includes the steps of establishing a correspondingpressure state response (PSR) model index system for each evaluation index element under a cultivated land requisition-compensation balance policy; adopting a TOPSIS method to calculate a pressure index evaluation value, a state index evaluation value and a response index evaluation value under the PSR model index system; adopting a coordination index function to calculate a coordination degree value between the pressure index evaluation value, the state index evaluation value and the response index evaluation value. Through the method, the PSR model embodies the interaction between humans andthe environment, emphasizes the influence of population, society, and economy on policies, and can comprehensively evaluate the whole process of policies, effectively making up for the above defects..

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a method for evaluating the performance of cultivated land occupation and compensation balance based on the PSR model. Background technique [0002] With the continuous deepening of the reform of my country's land resource management system, the concept of equal emphasis on the management of cultivated land quantity and quality has gradually penetrated into all aspects of cultivated land protection. The lack of implementation of the balanced cultivated land occupation and compensation policy is mainly due to the lack of a scientific and reasonable method to test the effect of policy implementation, which also shows that there are defects in the performance evaluation system of the balance of cultivated land occupation and compensation. Therefore, how to evaluate the effectiveness of the balance policy of cultivated land occupation and compensation is of great signifi...

Problems solved by technology

However, in the process of implementing the balance of cultivated land occupation and compensation, human factors and social, economic and environmental factors will all have an impact on the implementation effect, so a comprehensive and comprehensive evaluation only from a single point of view rather than from a systematic point of view will have a certain impact on the results. error, more impractical

[0006] There are certain limitations and defects in the existing commonly used grade conversion method, because there are human factors in the process of compiling the grade conversion coefficient

In order to make the maximum grade conversion coefficient smaller, there is a phenomenon of artificially adjusting the sample points, raising the grain production capacity of low-grade agricultural land, and lowering the grain production capacity of high-grade agricultural land, resulting in a certain deviation between the grade conversion coefficient and the actual situation. It has an impact on the evaluation results of the balance performance of cultivated land occupation and compensation
