基于南京市城市森林资源状况和指标体系的科学性、动态性、可行性原则指导,建立生态服务功能评价指标体系。基于3S技术获得2000年和2007年各指标因子量化的可靠基础数据,用层次分析法(AHP)分析影响森林生态服务功能的主导因子和相互关系,采用权重加权法最终评级。结果表明,近年来南京市森林生态建设卓有成效。
Based on the scientific, dynamic and feasible principles of urban forest resources in Nanjing City and the indicator system, the index system of ecological service function evaluation was established. Based on the 3S technology, the reliable basic data of the quantification of each indicator in 2000 and 2007 were obtained. Analytic hierarchy process (AHP) was used to analyze the dominant factors and their interrelationships that affect the service function of forest ecosystem and the weighted final weight was used. The results show that in recent years, the forest ecological construction in Nanjing has been fruitful.
