摘　　要：生态系统适宜度评价思想自提出以来,已得到了世界各国的基本认同。本研究主要从城市入手来分析和评估珠江三角洲城市生态系统适宜度的发展状况,采用社会统计学的方法,构建了体现城市结构、城市功能和城市协调度的垂直式和反映经济、社会、人口、资源、环境状况的水平式两者相结合的指标体系,选取1995-2004年10个年份的数据,对珠江三角洲9个城市的生态系统适宜度进行测算,并将10个测评年份的数据统一进行标准化处理和非负处理,实现了不同年份和不同城市的可对比化。划分了城市生态系统适宜度的类型,分析了类型的变化和由这些变化形成的城市生态系统适宜度发展的特点,并得出珠江三角洲城市生态系统适宜度增强、珠江三角洲城市生态适宜度3个垂直层次的发展稳定性不一致等结论。Theories of the ecosystem niche - fitness evaluation have obtained the various acceptance since statement. This research mainly analyzes and assesses the development of the Pearl River Delta urban ecosystem niche-fitness by researching cities. By the Social statistical methods, the index system has been constructed whichis combined of the two, that the vertical manifesting the urban structure, the urban function, the urban coordination, and the level reflecting the situation of economy, social, population, resources, environmental. Selecting the data of 1995 to 2004 10 years, through evaluating the ecosystem niche-fitness of nine cities of Pearl River Delta, and, standardized and nonnegative processing all of the ten years data, it has been realized that the contrast in different years and different cities. This study classifies types for the urban ecosystem niche-fitness, and then analyzes the changes of all types, analyzes the characteristics of the urban ecosystem niche-fitness which formed by these changes. Finally, it draws the following conclusions： （a） Pearl River Delta urban ecosystem niche-fitness is enhanced; （b） On the three vertical levels, the development stabilities of Pearl River Delta urban ecosystem niche-fitness are inconsistent; （c） The model of Pearl River Delta urban ecosystem niche-fitness is the intrinsic factors influencing development model; （d） The evaluation of Pearl River Delta urban ecosystem niche-fitness is influenced largely by the abnormal changes of index.
