Evaluation Of Development Zones Land Intensive Use In Chongqing City

Land is matter resource and environmental resources that the mankind relies on existing and developing, also is matter carrier that what human society need much else natural resource.Land use is the embodiment that the ground form what human activities bring upt in natural environment.Currently,under the practice of urban sprawl and urban planning, development zones as important carrier that enterprise develop goingtoscale, already become growth pole of urban economics,and play an important part in the development of urban economics,it's pattern and means of land use play an important and reference part in future planning and attract investment of development zones.Research land intensive use of development zones is bruche that remission contradict that current economic rapid development background land requirement increasingly and the capability of land supply are limited, realize to drive urban economics development target, intensivieren efficiency of land resources use and sustainable utilization of land resources, regional social and economic development, urbanization drive etc has a great academic and practical significant.Chongqing City is heart that Chongqing developed,and create better conditions to development zones.Development zones of Chongqing City exploit the area of land 79.46 square kilometers,thereinto the national level development zones cover an area of 27.56 square kilometers, the provincial level development zones cover an area of 51.90 square kilometers.This research direct at the problem of land intensive use of development zones, eva luation of development zones land intensive use via example. According to the survey s et up geodatabase of land use and select 14 related indicators of land intensive use of de velopment zones, from three aspect is that behaviour of land use, the efficiency of land, manage performance, establish an four layers evaluation system that is make up of gene ral objective layers, objective layers, subgoal layers and indexlayers. Through set up evaluation criterion of intensive land use of development zones,evaluation of Chayuan industrial park land intensive use use fuzzy mathematics and calculate and analysis the potential of land intensive use. Research results show:The level of land intensive use lie general intensive use[degree of membership is 0.4609(less than0.5) compare withl, is a certain distance away], The level of land intensive use is ordinary. From the scores of very target layers and subgoal layers, each layers are far difference and scores are quite low.From the constitute of potential of land intensive use, the area of tolerableness supply land is 49.26ha, the area of tolerableness supply industrial land is 28.92ha. To i mprove site coverage,overall volume terms,output intensity of industrial land the funds on fixed assets can excavation the area of land 47.10ha,88.29ha,28.17ha,23.06ha.In the potential of tolerableness excavation land intensive use, intensity potential is the larg est(186.52ha), expand potential is the second(49.26ha), structure potential is the third (12.28ha), management potential is the lowest(0.00ha).Contrast to Others three sibling development zones of Chongqing City in the model of grey incidence. Through consideration found that development zones lie different developmental stage, the level of land intensive use are different,from the degree of marketization of land supply analysis development zones lie different developmental stage influence its level of land intensive use,and find influencing factors of land intensive use:the level of land intensive use from superior to inferior is Konggang park>Chayuan park>Jingkou park>Xiyong park; from the degree of marketization of land supply calculate that Chayuan industrial park is belong to developmental stage of relative maturity market economy; Through calculate the influencing factors of land intensive use, work out six Independent variables is significantcorrelation bound up with land intensive use, work out important influence coefficients of every Independent variables and ranking of important influence coefficients is industrial land ratioâ†'site coverageâ†'land constructed ratioâ†'land supply ratioâ†'paid land use ratioâ†'output intensity of industrial land. Based on researches above, put forward relevance policy and proposal that raise the level of land intensive use of Chayuan industrial park.Through so study, can evaluation of development zones the level of land intensive use scientificly, offer decision and frame of reference to department of development zones planning and land management.
