广东省土地利用与生态环境协调发展空间差异研究

在构建土地利用与生态环境的协调发展评价模型基础上,分析了广东省21个城市土地利用与生态环境的协调发展程度。研究结果表明:①广东省各城市的协调度与协调发展度都存在着明显的地域差异,协调发展水平整体上表现出珠三角大部分城市的协调发展水平好于山区、东翼和西翼的规律,而且与区域经济发展水平具有较强的相关关系;②广东省各城市土地利用与生态环境的协调度与协调发展度在空间上分布具有一定的对应性;③根据协调度和协调发展度可以将广东省21个城市分为6类,分别体现了经济发展、自然条件和政策等作用的差异。

Spatial Difference of Coordinated Development between Land Use and Eco-environment in Guangdong

On the basis of constructing an evaluation model of coordinated development between land use and eco-environmen,spatial distribution of degree for coordinated development was analyzed in Guangdong.The results showed that:firstly,there obviously existed regional disparity of the coordination degree and coordinated development degree,the overall level of coordinated development of most cities in the Pearl River Delta region being higher than those in the north mountainous region,the east region and the west region,while there was a strong correlation relationship between the degree for coordinated development and the level of economic development.Secondly,the spatial distribution of coordination degree and coordinated development degree had some correspondence.Thirdly,the 21 cities in Guangdong would be divided into six categories in accordance with coordination degree and coordinated development degree because of differences in economic development,natural environment,policies factors,and so on.
