An evaluation method for implementing double balance for quantity and quality of tilled land during occupation and supplement

Abstract

The invention relates to an evaluation method for implementing double balance for quantity and quality of tilled land during occupation and supplement, belonging to field of territorial resources management and sustainable utilization and evaluation. In the invention, a model is established to measure and calculates grain production capacity of tilled land of different quality based on stable index for representing grain production capacity of tilled land, constructs model of tillage land quantity for converting to equivalence coefficient. When tilled land quality is superior to supplementary tilled land quality, the grain production capacity is ensured by increasing area of supplementary tilled land during course that the tilled land is occupied by non-agricultural construction, which provides technical support for enforcement of policy of tilled land balance and overall appraisal of quantity and quality of tilled land, thereby ensures grain safety of country.

Description

Technical field: [0001] The invention relates to an evaluation method for realizing the dual balance of cultivated land quantity and quality in the process of balance of cultivated land occupation and compensation, and belongs to the field of land resource management and sustainable utilization evaluation. Background technique: [0002] In the face of the current trend of decreasing arable land quantity, declining arable land quality, and the loss of arable land productivity being gradually eroded by rapid urbanization and industrialization, how to protect the increasingly scarce arable land resources has become the focus of concern of the government and all sectors of society. Although China adopts the strictest cultivated land protection system, it proposes that if non-agricultural construction occupies cultivated land, according to the principle of how much it occupies and how much it will be reclaimed, the unit that occupies the cultivated land is responsible for reclaimi...

AI Technical Summary

Problems solved by technology

[0004] The key problem causing the current inability to realize the double assessment of the quantity and quality of occupied cultivated land is that the evaluation results of cultivated land quality are mostly expressed in the form of relative values, which can only measure the relative quality of cultivated land and cannot represent the capacity of cultivated land production capacity. The evaluation results of cultivated land quality expressed in the form of absolute values ​​such as temperature productivity and climate productivity are also in theoretical calculations and cannot be applied to the actual calculation of the quantity and quality of the balance of cultivated land occupation and compensation.
