Land Intensive Utilization Evaluation Of Liling City

Our country is in a period of rapid development, and the land which is the carrier of human survival, the basis of social and economic development, plays an important role.In the process of human land use expansion construction, economic development, engaged in various activities, there are some of the phenomenon, such as unreasonable utilization, low degree of intensive, destruction and serious waste of land and so on.As the top four strong counties of Hunan, Liling has a typical representative in terms of land use status.Therefore, carrying out the evaluation of land intensive use in Liling can provide a basis for local government policy making, planning, changing land use patterns, and provide a reference for other counties in the intensive use of land.By using the statistical yearbook, bureau of land and resources related parameter, and on-the-spot investigation data, referencing the relevant norms and standards of countries on the construction of ecological county, Zhuzhou area evaluation of land intensive use assessment, building evaluation index system model for comprehensive evaluation of land intensive utilization in liling city in 2013 through the analytic hierarchy process and multi-objective analysis method, this article with the whole area as the objects of evaluation in liling achieved the following results:1)Building the evaluation index system model, such as three criterion layers of the ecology, society, environment, four domain layer of Land eco-utilization degree, land use intensity, management performance, input-output level, fourteen index layers of urban population density, land supply rate and so on, we can determine the weight of evaluation indexes and the index ideal value;2)Conformed the standard of intensity classification, which is greater than or equal to 85 for intensive,70-85 for more intensive,50-70 for more extensive, less than or equal to 50 for extensive use;3)Calculate the Liling in 2013 at the time of the land intensive evaluation score is 83.93, belong to the more intensive land use status. The ecological index score of 90.72, social indicators score 88.22, score 78.43 economic indicators;4) per unit of GDP consumption underground drop rate index score 31.15, land supply rate index score 78.79, investment in environmental protection accounted for the proportion of GDP index score 82.29, all urban fixed asset investment index score 9.182 etc., analysis of the Liling there GDP of land dependent larger; the stock of land larger; the input and output of land rate is low; the illegal use more, ecological environmental protection is not enough.Conclusion:Liling in annual evaluation of land use is intensive state, but in order to improve the land input output level, the optimization of the land use structure and crack down on illegal behavior, invigorated the stock of land, improve the land supply rate, pay attention to ecological environment prevention and protection improvement, intensive use of land rise space is huge.
