| The coordinated development of intensive urban land use and ecology of the city are the core of sustainable development.The patterns of the city land can result in ecological environment destruction the cities through the influence of the atmospheric environment, water environment, noise environment and biological diversity. And one better ecological environment is the basic part of the city sustainable urban development and urban land-intensive use. Only the coordinated development of the Land Use and Ecological Construction can make a guarantee to the smooth progress of sustainable development of city.At first the article makes a brief exposition of the basic theories of the intensive use of land and ecology construction at the basic of a abundant of data on widely gather collecting,analysis the current world research of the intensive use of land and the ecology construction . Then chooses the western city Xi'an as the research city, make some certain analysis of the city current situation of the intensive use of land and ecology construction ,and then conform the driving factors of the intensive use of urban land and the limiting factor of the ecology construction.On the foundation of the analysis the intensive use of land and ecology construction qualitatively,the article construct the index system of the intensive use of land and ecology construction,and confirm the weight of each indicator by the principal component analysis method. Next make certain analysis of Xi'an Land Use and Ecological Construction and coordination through the composite index method, static coordination degrees, the coordinated development of the level of coordination models and dynamic model Then on that propose the solution of Xi'an Land Use and Eco-development.The study suggests that: 1 the characteristics of land use in Xi'an is: the less area of per capita arable land; the development of industrial land is rapidly increase and arable land is rapidiy decline ; the input of using land is not equal with the output of effectiveness.2 In the period of 1994 to 2006, the level of Land Use of Xi'an increase firstly and then reduced , but the level of ecology construction in Xi'an has been grown in a great speed,and in 1998 exceeded the level of intensive utilization of land.3 In the period of 1994 to 2006, static coordination of Land Use and Ecological Construction in Xi'an experienced one process as serious disorder - moderate disorder - primary coordination - brink co-ordination .4 In the period of 1994 to 2006, the level of coordinated development between the Land Use and Ecology construction in Xi'an have experienced a recession -as the brink of imbalance - just to coordinate the development process, the development of sub-categories gradually developed from the development of eco-building lagging behind d to the level of the intensive use of land lagging behind.5 In Xi'an, the extent of the coordinated development between the intensive use of land and ecological construction has been on the continuously improved track.6 Made some suggests for Optimize: Adjust land use structure, to contain the decreasing trend of area of arable land in Xi'an; let market make full play on the effective allocation of land resources; Pay attention to land development and reclamation, make the full utilization of land resources; Set up the ecological and human landscape of organic integration into the pattern of geographical characteristics; Increase the green land of city, improve the ratio of the vegetation coverage, change industrial layout, reduce the urban pollution; Make urban ecological planning, and the patterns for Environmental-Friendly Land Utilization ,promote of Xi'an the coordinate development of the Land Use and Eco-construction. |
