摘要

土地利用与区域生态安全格局紧密相关

本文在国家尺度上

选择中国2004~2014年的面板数据

将CO

排放纳入土地利用与生态安全耦合协调评价指标体系

运用熵值法、综合评价函数和耦合协调模型测算土地利用与生态安全的耦合协调度

在ArcGIS软件支持下

分析31个省市区土地利用与生态安全耦合协调度的时空演变规律. 结果表明: (1) 2004~2014年间

31省市区土地利用综合评价指数、生态安全综合评价指数、耦合协调度指数整体上升

反映我国近年来

随着土地利用程度的提高

生态安全水平向良性趋势发展; (2) 在土地利用与生态安全耦合度的空间分异上

西部地区的耦合度主要处在低水平耦合阶段和拮抗阶段

中部地区多在磨合阶段

高水平耦合阶段主要是东部沿海地区

体现了区域土地利用与生态安全的耦合水平呈梯度空间分布; (3) 从2004、2009和2014年的截面数据表明

近年来

我国大部分省市区土地利用与生态安全协调度属于中度协调耦合阶段的土地利用制约型

高度协调耦合区间的省市区数目减少

没有省市区处于极度协调耦合区间

说明我国各省市区土地利用与生态安全的协调发展水平还较低下. 研究区域土地利用与生态安全的耦合协调发展

有利于促进区域的土地合理、高效利用和解决生态环境问题.

Abstract

Land use and regional ecological security pattern is closely related. The panel data of China from 2004 to 2014 are selected on the national scale for this study. The CO

emission is integrated into the evaluation index system of land use and ecological security. The entropy method

the comprehensive evaluation function and the coupling and coordination model are used to estimate the land use and ecological security. And the coordination and coordination degree of land use and ecological security in 31 provinces and municipalities were analyzed with t

he help of ArcGIS software. The results showed that the land use comprehensive evaluation index

ecological security comprehensive evaluation index and coupling coordination index of 31 provinces and cities increased as a whole in 2004-2014

which indicated that in recent years

with the improvement of land use

the ecological security level had a positive trend development; that in the spatial differentiation of coupling degree of land use and ecological security

the coupling degree of the western region mainly lies in the low-level coupling stage and the antagonistic stage

the middle area is in the running-in stage and the high-level coupling stage is the eastern coastal area

and the coupling level of land use and ecological security is gradient spatial distribution. The cross-sectional data from 2004

2009 and 2014 show that in recent years

the coordination degree of land use and ecological security in most of China's provinces and municipalities is a land-use type with moderate coordination and coupling

there is no extreme coordination between the provinces and municipalities in the coupling interval

indicating that the provinces and municipalities of China's land use and ecological security of the coordinated development level is still low. The study of the coordinated development of regional land use and ecological security is conducive to promoting the rational and efficient use of land in the region and solving the ecological and environmental problems.
