长江三角洲地区资源环境与经济增长脱钩分析

基于环境压力与经济发展,应用脱钩理论和改进的弹性分析法脱钩程度判定标准,对2000-2009年长江三角洲地区16个城市的环境压力与经济发展脱钩程度、时序演变和呈现的规律进行定量评价与综合分析.结果显示:长江三角洲地区资源环境与经济增长主要经历了从相对脱钩Ⅱ-相对脱钩Ⅲ-相对脱钩Ⅱ-相对脱钩Ⅰ,2000-2005年经济增长对资源环境冲击不断增强,而2005-2009年冲击有所减小;该地区资源环境压力各指标与经济增长的关系以相对脱钩为主,且存在时间上和指标间的差异;长江三角洲地区城市群多数时期都处于相对脱钩状态,其中10个城市资源环境与经济增长的脱钩关系呈现"N"型趋势,且多数城市2004年和2005年达到最高,上海在绝对脱钩和相对脱钩Ⅰ徘徊,而江苏和浙江内部差异明显.

Decoupling Analysis between Economic Development and Resources and Environmental of the Yangtze River Delta

Based on the application of the decoupling theory between environmental pressure and economic development and improved elastic analysis decoupling degree judgment standards, this paper attempted to make quantitative and comprehensive analysis of the features or rules of temporal-spatial evolution of decoupling degrees between resource environment and economic development of the Yangtze River Delta, with a time span from 2000 to 2009. The results show that: the relationship between resources-environment and economic growth of the Yangtze River was generally in the order of relative decoupling Ⅱ-relative decoupling Ⅲ-relative decoupling Ⅱ-relative decoupling Ⅰ, and the impact between economic growth and resources-environmental enhanced the impact during 2000-2005, then reduced during 2005-2009; the relationship between each index of resources-environment and economic development was generally in a state of relative decoupling, and decoupling degree of resource consumption and environmental pressure and comprehensive resource presented differences in time and indexes; in most of the time period, the Yangtze River Delta was in a relatively decoupling state, including 10 cities resources environment and economic growth on the decoupling relationship of "N" trend, and the pressure between economic development and resources-environment reached the highest in 2004 and 2005 in the Yangtze River Delta. Shanghai was wandering between absolute decoupling and relative decoupling Ⅰ, and Jiangsu and Zhejiang showed apparent internal differences.
