摘　　要：在构建城市土地集约利用与生态环境协调发展评价模型的基础上,分析了1995年以来中国城市土地集约利用与生态环境协调发展程度的时空分布。研究结果表明:(1)从时间上看,协调度等级由初级协调转为良好协调,但协调度近年来呈现下降趋势,协调发展度整体上逐年增加;(2)从空间上看,中国省区协调度与协调发展度都存在着明显的区域差异,且协调发展水平整体上表现出东部地区大部分省份高于中西部地区的规律,而且与区域经济发展水平具有较强的相关关系;(3)按照协调度和协调发展度将31个省区分为7类,分别体现经济发展、自然条件和政策因素等差异。应在提高城市土地集约利用水平的同时,不断加强生态环境保护建设;开展城市生态规划,建立环境友好型土地利用模式,有效促进城市土地集约利用与生态环境协调发展。Spatiotemporal distribution of coordinated development degree for urban intensive landuse and ecological environment in China since 1995 was analyzed by constructing an evaluation model for coordinated development.Results from the study showed that temporally,grade for coordination degree changed from primary coordination into good coordination.In recent years,however,coordination degree exhibited a downward trend and coordinated development degree,on the whole,gradually increased year by year.Spatially,there was obvious regional disparity in coordination degree and coordinated development degree of China′s provinces.The overall coordinated development level in most provinces of the eastern China is higher than that in the middle and western China.There was a stronger correlation between coordinated development degree and economic development level.In accordance with coordination degree and coordinated development degree,the 31 provinces of China could be divided into seven categories in order to reveal the differences in economic development,natural environment,policies factors,and so on.Coordinated development between urban intensive landuse and ecological environment should be effectively promoted by improving the level of urban intensive landuse,enhancing ecological environment protection and construction,carrying out urban ecological planning,and establishing environment-friendly landuse pattern.
