城市生态系统的模拟方法：灵敏度模型及其改进

评估城市生态系统的持续发展能力，探讨其持续发展对策是一个复杂的动态问题，需要运用动态的模拟方法进行。由德国著名生态控制论专家Ｆ．Ｖｅｓｔｅｒ和Ａ．Ｖ．Ｈｅｓｌｅｒ教授提出的“灵敏度模型”方法，将系统科学思想、生态控制论方法及城市规划融为一体，解释、模拟、评价和规划城市复杂的系统关系，是模拟城市生态系统很好的方法。本文对该方法进行了改进。改进后的“灵敏度模型”为评价城市持续发展能力、探讨其持续发展对策提供了新的思路。

A SIMULATION METHOD OF URBAN ECOSYSTEMS: SENSITIVITY MODEL AND ITS IMPROVEMENT

Due to the complex dynamic processes of estimating the sustainability of urban ecosystems and of exploring strategies for their sustainable development,dynamic simulation methods are needed.The Sensitivity Model developed by German Scientists Prof.F.Vester and Dr.A.v.Hesler on the basis of system science,biocybernetics and urban planning methods,which can be used to illustrate,simulate,evaluate and plan the complex relationships within an urban ecosystem,is a good method for simulating urban ecosystems.The authors improved the Sensitivity Model in their collaboration with prof.F.Vester and Dr.A.v.Hesler.The improved Sensitivity Model provides a new way of thinking for estimating the sustainability and exploring the strategies for sustainable development of urban ecosystems.
