摘要/Abstract

摘要： 在构建城市化综合指数与生态综合指数的指标体系和评价方法的基础上,提出了综合响应度模型,并对江西省进行了分析。研究显示:①改革开放以来,江西省城市化综合指数逐步提高,现已进入城市化快速发展时期;而江西省生态综合指数及其分量不仅表现波动规律,还呈现出不同的变化特征。②1978~1990年间的生态综合指数及其分量与城市化的综合响应度普遍高于整个考察期和1991~2005年间的综合响应度,反映出在1978~1990年间江西省生态对城市化进程具有更强的敏感强度。可见在城市化增长阶段与生态质量改善阶段并不具有一一对应的关系,其结构变异不仅和城市化本身的推进模式有关,更重要的是和生态建设及保护的方式有关。

Abstract: This paper analyzes the temporal response characteristics and total response intensity for ecological quality to urbanization level in Jiangxi province.Firstly,the paper designs the index system and appraisal model of comprehensive indexes of urbanization level and ecological quality with hierarchical synthetic method,and respectively calculates the indexes and their components.Next,the paper puts forward a comprehensive response degree model by means of elastic formula in the field of economy,which is expressed as cj=∑nt=11Tθj(t)(j=1,2,k;t=1,2,…n),and analyzes the comprehensive response degrees with the calculated comprehensive indexes of urbanization level and ecological quality.The calculated comprehensive indexes of urbanization level and ecological quality show:(1) The comprehensive urbanization level in Jiangxi province has increased gradually since the reform and opening to the outsides world.Two periods can be identified in the process,of which the former is a slower development stage during 1978-1990 and the latter a relatively rapid stage during 1991-2005.The present urbanization process in Jiangxi province has entered a rapid stage.(2) The comprehensive index of ecological quality and their components take on different curves.Among them,the index of ecological level and the index of ecological resistance ability are the same to the comprehensive indexes of ecological quality,which takes on an"U-shaped" curve,but the index of ecological pressure presents a periodic variation.The calculated comprehensive response degrees reveal:(1) The comprehensive response degrees and their components for ecological quality to urbanization level in Jiangxi province are generally higher than the entire inspection period and in 1991-2005,indicating that there is a much stronger sensitive intensity during 1978-1990 for ecological quality to urbanization process.Obviously,there doesn't exist a corresponding relationship between the urbanization process and the changing ecological quality,which concerns with not only the advancement pattern of urbanization itself,but also the way of eco-environment construction and protection;(2) The established comprehensive response degree model is easy to operate,and to the degree can promulgate the comprehensive response condition,but there are some limits to the application because its foundation is elastic formula in the field of economy,and the reflected response relations are only fitting tendencies for two variables in a certain period of time.Therefore,there exist not only the least samples but also the fitting accuracy for the model to be applied.

Key words: urbanization, comprehensive index of ecological quality, comprehensive response degree, Jiangxi province
