An Study On Ecological-Using For Land Resource In ChangSha

The land is the basis for human survival and development, the most important natural resources and environment factor. As the human population grows, pollution and destroy for the Earth surface layer from human activity also increases. It's the topic of realistic meaning how to use the land resources reasonably and economically.The paper is on an Ecological-Using subject for land resource in Changsha , this pole have the topic of realistic meaning , and expound this topic realistically and in depth, and refer to the literature review of the current progress in the studies, formation studies overview, and make a summary. first expound the Ecological-Using for land resource, realistically and in depth, from a theoretical point of view, and refers to a systematic evolution process, minute analysis about the Ecological-Using for land resource .Secondly, combine various kinds of theories like economics, ecology, and geography...etc. and across an academics theory, adopt a chart research, more methods like analysis, etc, make use of condition, dynamic state variety and carry on substantial evidence ,survey and analyzed the land utilization of Changsha City in 2000-2008 years. Then, depend on a propping up of substantial evidence research, analyzed and evaluated Ecological-Using for land resource of Changsha City. On this foundation, point out currently the existent problem in the Changsha land exploitation: a deficiency land ecological environment , scale in the city extends mainly and is a postpone type outside; The city is used structure and allocation not reasonable, the land using low-efficiency; The farmland area continuously reduces, the farmland quality descends, the farmland protects situation rigorous; The land environment is weaker, program ecosystem imperfection. Combine to investigate its reason to then lie in a market out of order is as out of order as government. Last but not least, passes to draw on experience of the United States of America and Wu Han City about Ecological-Using for land resource ,and puts forward a homologous counter-plan suggestion for the land use in Changsha City. Put forward the perfect Changsha land ecosystem makes use of of counter-plan suggestion, namely the dish lives to save to measure a land and appropriately expands a Changsha City land to use a ground of space; Is excellent the land turning a city to set up with the ground, raising a city to make use of efficiency; Enhance a farmland protection, strengthen farmland protection system construction; Strengthen a land exploitation programming management, construct land eco-system in the city.
