摘　　要：推进耕地集约利用,是新发展阶段解决中国土地供需矛盾的重要途径。本文在PSR理论框架下,构建了中国耕地集约利用评价指标体系,并基于熵权值的多因素综合评价方法、协调度函数和障碍度模型,分别测算了2005—2021年中国耕地集约利用程度,以及影响耕地集约利用的障碍因子。研究发现,2005年以来,中国耕地集约利用水平整体上呈现上升趋势,但是,仍处于基本或者比较集约水平。PSR框架下各子系统之间的协调性并不稳定,特别是2014年之后,呈现下降趋势。由此表明,当前中国耕地资源利用仍处于粗放阶段。同时,影响中国耕地集约利用的障碍因子也会随着时间推移而发生变化。Promoting the intensive use of arable land is an important way to solve the contradiction between land supply and demand in China in the new development stage.Under the framework of PSR theory,this article constructs an evaluation index system for the intensive use of arable land in China,and measures the degree of intensive use of arable land in China from 2005 to 2021,as well as the obstacle factors affecting the intensive use of arable land,based on the multi-factor comprehensive evaluation method with entropy weights,the coordination degree function and the obstacle degree model,respectively.This article finds that the level of intensive use of arable land in China has shown an overall upward trend since 2005,however,it is still at the basic or relatively intensive level.the coordination among subsystems under the PSR framework is not stable,especially after 2014,showing a decreasing trend.This indicates that the current utilization of arable land resources in China is still at a rough stage.Meanwhile,the obstacle factors affecting the intensive use of China's arable land will change over time.
