Research On Evaluation Of Intensive Land Use Base On Compact City Theory

Compact city serves as a feasible mode of urban sustainable development, for its idea of high density and high efficience is profoundly significant to urge the spreading land issues and increase land utilization rate.Hence, this paper mainly focus on the evaluation of intensive land use on the introduction of compact ci ty theory, and founded an evaluation system guided by urban land economic output、 degree of urban space compression、 urban operation efficiency、 potential of urban land use potential.On the way of evaluation, the paper choices composite index evaluation method, and build an evaluation model. On evaluation index weight, this paper focuses on entropy evaluation method, and improved by efficiency coefficient method. In addition, this paper proposed targeted advices via coordinate coefficient analysis, composite index analysis, multivariate regression analysis of composite index and factor value on the evaluation of intensive land use on Xiangxiang City. The main achievements of this paper are:(1)Build an evaluation model of intensive land use based on compact city theory, taken the goal and tendency of future urban development into consideration, this model added integrated benefit index that reflects urban form and its function structure compared with the relative ones.(2)Via this evaluation model, I conducted an evaluation research on intensive land use in downtown area in Xiangxiang City, which indicates an increasing trend generally, except the year 2012. From the evaluation rating perspective, the city’s level of intensive land use is in the lower grade on the whole.(3)Evaluated coordinate index in four main factors that impacted intensive land use in downtown area in Xiaoxiang city, which shows a constantly reinforce in fluctuation and indicates a well-development trend in the city’s intensive land use condition.(4)Analyzed the obstruction factor of index Sign layer and criteria layer in intensive land use in downtown area in Xiangxiang city. The results of index sign layer shows that the main obstruction factors in evaluation are elasticity coefficient in urban population and land use, proportion of vacant lot, fixed investment and elasticity coefficient in land use, heterogeneity in land use, proportion in abandoned land, degree of fragmentation of residential land and public facilities and compact degree of urban form. The results of criteria layer shows that urban land utilization potential will be the number one factor that affects the intensive land use level in downtown area in Xiaoxiang city, and then the compact degree of urban operation efficiency urban space.(5)Based on the analysis above, this paper proposed suggests and strategies in increasing the level of intensive land utilization rate in downtown area in Xiangxiang City,including land utilization potential, controlling development, rational layout of land use and public transportation-oriented urban planning.
