Urban Land Intensive Use Of Theoretical Analysis And Evaluation Of Research

In recent years, as the urbanization speeding up in China, city regions and population continue to expand which cause demand for land increasing rapidly. As land resource is in wide shortage in China, the contradiction of supply and demand for each type of land (including farmland, construction-land and eco-land) are becoming increasingly acute. First, vast population and limited land made gross land be in short supply, therefore, the quantitative extensive growth is difficult to continue; Second, the low efficiency of land-use and unreasonable land structure cause spare and waste in existing land. Third, a number of places to seek short-term and local interests at the expense of the scarce land resources. The acts, exacerbated the supply and demand of land conflicts brought about the economic and social development of a series of contradictions. To deal with the reality of land-use background, the ideas of intensive land-use have been built up in many cities in China and explored in practice. Wuhua District is one of the main urban areas of new Kunming building, the land issue is particularly important.In this article, hold on the principle of land for reasonable protection, to further develop the idea of land-intensive. Through establishing urban land-use system and its three subsystems,different quantitative methods have been utilized from macro and middle layers to evaluate and compare the intensive extent for every system and subsystems. make a systemic theory analysis and evaluation study on the land intensive utilization field, and then the measures have been proposed.The main Research of this article includes:①The new connotation of urban land intensive utilization has been defined. Under the guidance of significant thought of "constructing harmonious socialist society" "sustainable development", the new connotation of urban land intensive utilization based on the macro-layer has been defined in this article;②The new evaluation index system of urban land intensive utilization has been constructed. Choose the urban land-use system integration as the evaluation subject of intensive extent from macro-layer, and choose the three subsystems as the evaluation subject of intensive extent from middle-layer in this article. The selected angles and implications of evaluation indexes of every system and subsystems are different from the former researches;③The evaluation achievements of intensive extent of different land-use types which aimed for Wuhua district has been gained. Through adopting four different kinds of quantitative evaluation models for land-use system and its three subsystems in Wuhua district, and combining with data from investigation, use the statistical methods and the "3S"technology to assisted analysis.④The measures and proposal aimed for the different land types of Wuhua district, which improve intensive extent have been given.
