Abstract:

Along with the presentation of scientific development view and the increasing contradiction of land supplydemand,how to realize coordinated development of society,economic and ecology as well as among different regions through the reasonable land development is an emergent problem .In this paper,spatial differentiation of land development suitability from the point of land supplydemand was studied selecting Jiangsu Province as an example.Firstly,the indicator systems of land supply restriction and land demand were established respectively.The indicator system of land supply restriction consists of 9 indices form the aspects of the protection of arable land resource and ecoenvironment.The indicator system of land demand consists of 19 indices from the aspects of the status and changes of population,economy and investment,output efficiency of economic input elements,perfect degree of basic foundation,land price and industry condition.Then the spatial differentiations of land supply restriction and land demand were analyzed by applying the weighted multiplefactors synthetic appraisement method.Simultaneously,the degree of land supply restriction and land demand were classified into four grades of high,relative high, moderate and low.Based on the above,Jiangsu Province was divided into four types of land development suitability applying classification matrix method,i.e.high suitability,relative high suitability,moderate suitability and unsuitability.At last,the development orientation of each type was presented respectively,which are meaningful for sustainable land use and coordinating the harmonious development of socioeconomic and ecology in Jiangsu Province.
