Study On Structure Pattern Of Eco-city Physical Spatial System

Since urban eco-system has came into being, its intrinsic broken characteristics break the steady sate of other ecosystems on the earth. This situation causes the division of work and coordination of effort among different ecosystems pushing our biosphere to unite into a comprehensive perfect system-Global life system. So, the situation of urban eco-system should make notable impacts on the whole environment of world and influence the balance of all ecosystems. Being a complicated ecosystem, it is very difficult to keep its regular station. Because of its every part's function must depend on the physical space system, the physical space system becomes the key to keep the balance of urban ecosystem.This paper intended to research and analyze the inherent development law of urban ecosystem's physical space system, and set a new concept of land-use and eco-planning of spatial development for all organisms (include people and other living things) living in urban area. In order to remedy the defects of normal land-use and spatial development planning that is only serves for human's society and economy. This paper tried to set up new physical-spatial structure patterns of urban eco-systems, which is on the base of crux structure law of spatial construction and focused on the standard of eco-city.In the process of research, this paper blazed some new trails: [1] Discover spatial structure of urban eco-system the characterized of screw structure with levels of organization; [2] Study the inter law and outer law of interaction between physical space system and function systems, such as Natural, Societal and Economical systems. [3] Found a network-like spatial structure pattern, which is complex concentrating eco-land use model—block and distracting eco-land use model—corridor. [4] To expound in order to build a high efficient communication and transport system in urban area, we must set up a kind of prefect system that is include two levels of organization—high speed road net and slowly road net. Those two networks must be individual and independent. At the same time they can exchange freely. [5] Set up a plane geometric figure to analyze the eco-effects of the different proportion of land for eco-use in urban area. Comparing the different patterns' eco-effects under common condition, are givensome important suggestions to present development.
