Abstract: With the accelerative development of cities,the problem of pollution is coming by, such as the pollutions of air,water,noise,solid waste and soil.These pollutio ns affect the major service functions of ecosystem in urban areas directly or in directly, such as reducing the capacities of air-filtering and microclimate regulation, subduing the functions of noise reduction,limiting the roles of rainwater drainage and sewage treatment,and causing the loss of cultural and recreational values which urban of cities and towns bring to us. Therefore,controlling the environmental pollution and protecting the urban ecosystem and its service function are the effective ways for the sustainable development of cities.
