【摘要】 以实证研究的方式,从区域层面深入探讨和拓展了生态位理论在城市研究中的方法和途径。在前人研究的基础上,改进生态位适宜度的数学模型,使计算更加简便。精心选取了反映经济发展(A)、基础设施(B)、生态环境(C)、居民健康和教育(D)以及城市吸引力(E)的5大类25项生态因子,构建指标体系,以江苏省为研究区域,计算出13城市1999～2004年间的6大类生态位适宜度(A、B、C、D、E及其平均值),并且运用ArcGIS、SPSS进行区域内城市生态位的时空对比和相关性分析。更多还原

【Abstract】 From a regional aspect,this paper probes into and expands the application of niche theory in urban research. Based on the previ-ous researches,enhanced mathematic model is built to make calculation easier. 25 indexes in 5 different areas are selected elaborately to es-tablish the index system. They are of economic development (A),the supply of public infra-structure (B),the environmental condition (C),the chances of health-care and education (D),city appeal (E). Taking Jiangsu Province as a research region,calculation of the urban eco-system of 13 cities from 1999 to 2004 is ac-complished as well as the analysis and conclu-sion with the help of ArcGIS and SPSS.更多还原
