摘要
协调好耕地集约利用与耕地生态安全之间的关系,是实现耕地可持续利用的必然选择.本研究通过构建珠江-西江经济带耕地集约利用与生态安全协调发展评价指标体系,分析 2011-2020 年珠江-西江经济带 11 个市的耕地集约利用与生态安全协调发展情况.研究表明,在时间上,珠江-西江经济带的耕地集约利用和生态安全协调发展度总体上呈逐年上升趋势,但广东段有 3 个市呈波动下降趋势,广西段各市均达到勉强协调发展和初级协调发展;在空间上,珠江-西江经济带各市的协调发展度存在着明显的地区性差异.研究结果可为珠江-西江经济带各市提高耕地集约利用水平、耕地集约利用与生态安全协调发展提供参考和新的发展思路.
Abstract
Coordinating the relationship between intensive use and ecological security of arable land is an inevitable choice to realize the sustainable use of arable land.This study analyzes the coordinated development of intensive use and ecological security of arable land in 11 prefecture-level cities in the Pearl River-XiJiang Economic Zone during 2011-2020 by constructing an evaluation index system for the coordinated development of intensive use and ecological security of arable land in the Pearl River-XiJiang Economic Zone.The results indicate that in terms of time,the coordinated development degree of intensive use and ecological security of arable land in the Pearl River-XiJiang Economic Zone generally showed an optimized upward trend year by year,but 3 cities in the Guangdong section showed a fluctuating downward trend,and all cities in the Guangxi section reached the degree of barely harmonious development and initial harmonious development;In space,there are obvious regional differences in the coordinated development degree of prefectures and cities in the Pearl River-XiJiang Economic Zone.The results can provide reference and new development ideas for cities in the Pearl River-XiJiang Economic Zone to improve the coordinated development of intensive use and ecological security of arable land.
