Growth Boundary Study Based On The Typical Hilly Cities Space Of The Ecological Security Pattern

Land resources are the basis of our survival and development, and the sustainable use of land is the basic guarantee for the full realization of sustainable development. With China’s rapid economic development, the continuous advance of the process of urbanization and the growing social progress and breeding of various regions in China’s urban space expansion problems and contradictions have become increasingly prominent, the city is facing tight supply and demand of land resources, low level of intensive use, land-use structure is irrational, inefficient urban land use the spread growth (expansion development) as well as the ecological environment deteriorating.Include economic, social, ecological, and other aspects of the balanced and sustainable development of urban development, urban expansion and can not be unlimited expansion of urban land development. After the contradiction between the awareness and understanding of urban development and urban land, exploring how to balance the city land for a reasonable extension of restricting urban unlimited expansion of the relationship between the two methods is that the current issues of most concern.Based on the problem of comprehensive expansion mode, ecology, economy and other factors to consider, learn at home and abroad of the urban growth boundary theory and method to judge the experience of the Road to the hilly urban land expansion and urban Growth Boundary, based on the research of the ecological security pattern, explore the hilly city construction, environment and other factors determine the the clear city rigid and flexible growth boundary determination method, which summarizes the definitions of a hilly urban growth boundarya relatively intuitive analysis methods, to help in the adjustment of urban land by epitaxial extensive growth to intensive growth of the connotations of the more reasonable development, and improve the utilization of urban land use of urban land resources as efficiently as possible, to maximize easethe city’s rapid economic development brought about by a shortage of land supply and demand, and to improve and protect the city’s ecological environment, and realize the urban land sustainable development. This article explores explore the stage, but clear and determine a reasonable space of the urban growth boundary, to the ecological health of the growth is where the current trend of urban expansion, will become the current urban development research is at a preliminary theoretical study and practical focus and hotspots.
