中文摘要：

研究快速城市化与工业化地区的生态用地不仅要关注环境污染与生境退化的影响，而且还应重视生态用地对区域环境质量的调节与改善效应。南京是长江三角洲地区的重要中心城市，生态用地保护对维护其“山水林城”的环境特色具有重要意义。采用TM卫星遥感影像解译与空间分析等方法，得出全市生态用地占土地面积的15％，按功能的适宜性与相近性，归并划分出水源涵养、河湖湿地、风景名胜和地质遗迹4个类型区，且前两个类型具有较强的空间优势；选取表征环境功能重要性的12个指标，评价得到极重要区占全市生态用地19％，较重要区占56％，重要区占25％；综合考虑生态用地对城市化与工业化空间发展的环境调控作用与加强污染治理和生态保护的协调，构建包含11个环境源强的4个生态环境调控组团，提出了禁止、限制各类活动以及保护生态环境的对策。

英文摘要：

Study on ecological land in rapidly urbanized and industrialized region not only needs attention to the effects of environmental pollution and eco-environment degradation,but should emphasize on its regulation and amelioration function upon regional environment. As one of the most important cities in the Yangtze River Delta, protection of ecological land is of great significance to maintain its local environment characteristic famous for ＂Landscape city＂. Firstly, this paper calculated the ecological land area by exploring the methods of TM remote sensing and spatial analysis, which reveals that ecological land of Nanjing City takes 15% of its total land areas. Secondly,based on the suitability and similarity of its function,the ecolog- ical land was divided into four patterns. Water source reserve, wetlands of rivers and lakes, famous scenic site and geological heritage, first two of which has relatively more intensive spatial advantages. Thirdly, we quantitatively investigated the importance of environmental function by choosing 12 most representative in- dications. According to the evaluation, the ecological land areas were partitioned into three levels.The most important area,relative important area and important area,taking 19%,56% and 25% of the total ecologi- cal land area respectively. Finally, four eco-environmental regulation groups including 11 environmental pol- lution sources were built, considering not merely environmental regulation function of ecological land for urbanization and industrialization, but coordination between pollution governance and ecology protection. Regulation policies such as prohibition or limitation of human activities and eco-environment protection were also suggested correspondingly.
