Study on Comprehensive Evaluation System for"Trinity"Protection of Cultivated Land in Jianghuai Region
摘要
Abstract
To accurately improve the protection level of the"trinity"of cultivated land quantity,quality,and ecology in the Jianghuai region and ensure regional food security,this study takes Anhui Province as a typical area.Based on the DPSIR model,a comprehensive evaluation in-dex system for food security-oriented"trinity"protection of cultivated land is constructed.The entropy weight TOPSIS method is adopted to conduct an empirical evaluation on three typical regions:Suixi County in northern Anhui,Qianshan City in central Anhui,and She County in southern Anhui.The advantages and shortcomings of regional protection are identified,and differentiated governance strategies are proposed.The results show that the constructed evaluation system includes 21 indicators,which are fully compatible with the regional characteristics of the Jianghuai region and the needs of food security;the protection level of the demonstration areas presents a pattern where southern and central Anhui are ahead of northern Anhui,and the overall coordinated protection mechanism in the province is imperfect;the three types of regions have formed differentiated protection models,with the core contradictions being quality and ecological anxiety in developed areas,imbalance be-tween utilization and protection in the central region,and output and environmental pressure in major grain-producing areas.Based on the eval-uation results,differentiated governance paths adapting to the"two balances and one freeze"system are proposed for the three types of regions,and it is suggested to build a provincial-level intelligent supervision platform for the"trinity"of cultivated land.This study can provide a scien-tific basis for the formulation and practical optimization of cultivated land protection policies in the Jianghuai region and enrich the theoretical system of cultivated land protection evaluation.关键词
