基于耦合协调度模型的永久基本农田优化调整方法研究
Research on the optimization and adjustment of permanent basic farmland based on the coupling coordination degree model:A case study in Qibin District of Hebi City
摘要
Abstract
The optimization and adjustment of permanent basic farmland is of great significance for achiev-ing farmland protection,land intensive utilization,and ensuring national food security.Objectives In order to optimize and adjust permanent basic farmland,Methods this study takes the Qibin District of Hebi City as study object to optimize and adjust permanent basic farmland.Form a dual perspective of comprehensive quality of cultivated land and landscape ecological security,a coupling coordination degree model based on these two factors is proposed.Based on the coupling coordination degree levels of the evaluation unit culti-vated land,the comprehensive quality of farmland is evaluated.Results The results indicate that the con-straint of landscape ecological security of cultivated land on the stability of permanent basic farmland fur-ther ensures the stable performance of the production function of permanent basic farmland and optimizes the territorial spatial pattern.Regions with high levels of coupling and coordination are mainly distributed in the development zone,Dalaidian Town,the demonstration area,and Juqiao Town,showing a distribution pat-tern of low in the west and high in the east.Priority should be given to adjusting the eastern cultivated land to permanent basic farmland.Based on the constraints conditions of designation rules,the preliminary delin-eation results of the coupling coordination degree model are optimized and adjusted.The designated areas for permanent basic farmland in the study area are divided into reserved areas(6 387.35 hm²),adjustable areas(5 473.07 hm²),removable areas(804.77 hm²),and unsuitable areas for adjustment(988.12 hm²).Conclusions The research method avoids the adverse effects brought about by solely considering the quality of cultivated land in the process of delineating permanent basic farmland.It fully considers the constraints effect of cultivated land quality and landscape ecological security on the stability of farmland production.It also takes into account the needs for ecological protection and the spatial layout of farmland,thereby en-hancing the rationality and scientific basis of the optimization and adjustment of permanent basic farmland.关键词
