摘要
城市生态系统稳定性直接影响到城市与人类的发展,文章对城市生态系统稳定性概念及表示方法进行了探讨,利用生态系统波动大小与总体发展趋势表示稳定性。并在此基础上从社会-经济-自然复合生态系统角度初步建立城市生态系统稳定性指标体系,利用主成分分析方法对2000~2008年扬州城市生态系统稳定性进行了实例分析评价,结果表明,2000-2008年间,扬州城市生态系统处于增长基本稳定状态。
Stability of urban ecosystems has a direct impact on the urban and human development The concept of urban ecosystem and stability of expression was discussed,with stability expressed by the use of ecosystem fluctuations in size and overall development trends.And on this basis,from the perspective of the initial establishment of complex ecosystem stability index system of urban ecological systems,using principal component analysis of Yangzhou urban ecosystem stability and evaluation results show that in the year 2000 to 2008,Yangzhou growth of urban eco-system is basically stable.
