Urban Planning Study Of The Optimization Features Of The Urban Complex Ecosystem

City is the assembled center of mankind. It is the fruit resulted from the development of economy, politics, science and technology of human society in certain stage. They are also the assembled place of material progress and cultural progress. So, to construct cities of good human being inhabited environment is always the goal which people diligently pursue. As the wheel of history sails into 21st century, questions of various aspects including resources, environment, population, economy, society and so on in the urban complex ecosystem appeared evidently with the transition of the economy society of our country and acceleration of urbanization process. So we should take kinds of measures to optimize the urban complex ecosystem, improve urban human inhabited environment and create more livable city.Taking land use and spatial layout as the core, Urban planning has the function of depositing the space resources, protecting the ecological environment, defending social justice, guarding public security and public benefit, thus promoting the urban economy, the social development and the ecological environment coordinated. Therefore, urban planning can play the important role in solving the existing problems in urban complex ecosystem.Based on this, the article firstly conducts the research on the optimization functions with urban planning to urban complex ecosystem, discusses the optimization ways and optimization methods with urban planning to urban complex ecosystem, and ,as well as for better optimized urban complex ecosystem, finds the way of urban planning of future development.The article put forward the new idea of the optimization with urban planning to urban complex ecosystem and initially establishes the theory system about the optimization function with urban planning to urban complex ecosystem. The main research results of this article are as follows:(1) Summarized the development history of western urban planning theories in the past hundred years. We can find that the optimization function with urban planning to urban system is heightening with the evolution of western urban planning thought.(2) Discussed the mutual influence factors and the mutual influence mechanism of urban planning and urban complex ecosystem.(3) Summarized the optimization way with urban planning to urban complex ecosystem from three aspects of the urban natural system, urban economy system and urban society system separately.(4) Separately discussed the optimization ways with urban planning to urban complex ecosystem from the four angles of view of relations of bodies, plan-making, urban space and public policy.(5) Based on the foundation of urban complex ecosystem, it has established the evaluation system of urban planning scheme. Through establishing the fuzzy comprehensive evaluation model, it designed the performance evaluation system to urban complex ecosystem after the implementation of urban planning.(6) It is proposed the development way of urban planning, including the development of the thought view of urban planer, the development of goal view of urban planning, the development of urban plan-making, the development of urban planning space control, for the sake of exerting the optimization function to the urban complex ecosystem better.
