| Abstract: | This methodological investigation deals with measurement and valuing of ecological service functions for urban green space. Social, economic and ecological dimensions for such types of function are analyzed and a concept " integrated ecological service functions"(IESF) is put forward for evaluation. Based upon this conceptual approach, an index system for measuring IESF for urban green space is established. With a methodological integration of fuzzy mathematics, decision-making analysis and Delphi method, an AHP fuzzy evaluation techniques for IESF for urban green space,called AFIFUG method, is developed. Such a method has beendirectly applied to the land use strategic planning of Tianjin out-ring green belt(TOGB), and its analysis results have been successfully put into operation. |
