摘要
结合山地城市特征和PSR概念模型,构建山地城市环境承载力评价指标体系和评价模型,以重庆市为例进行实证研究。结果表明:1该指标体系能反映山地城市环境承载力的各个方面,评价结果符合重庆市的实际水平;2研究期内,重庆市环境承载力呈现逐步上升态势;3人口增长与经济发展对环境造成的压力与日俱增,但在政府引导措施等因素的作用下,大部分压力指标得到有效控制,状态和响应指标呈现良好发展趋势。
Based on the characteristic of mountain city, this paper made use of the ＂pressure - state - response＂ model to build index system and selected evaluation method, then conducted the empirical research in Chongqing City. The results showed：OThe index system which was chosen could reflect the environmental carrying capacity for mountain city in all directions. The research results reflected the practical level of Chongqing. （2）The environmental carrying capacity for Chongqing was promoted during the study period. （1）The environmental pressure in Chongqing increased fast, which was caused by the population expansion of the city and social economy. However, most pressure index was under the control affected by government＇s guidance and other factors. At the same time, the state and the index of the response module was a strong improvement trend.
