摘　　要： 随着土地供需矛盾的加剧,如何通过土地资源的合理有序开发,实现社会、经济、生态之间以及区域之间的协调发展是一个迫切需要解决的问题。以江苏为研究区域,从供给约束及开发需求的角度,分别构建了土地供给约束及非农开发需求程度评价指标体系,其中：供给约束指标体系主要由水土资源约束和生态环境约束两个方面共9个具体因子组成;土地非农开发需求指标主要由人口、经济、投资水平及变化,以及经济要素产出率、基础设施完善程度、土地获取成本及产业基础等方面共19个具体因子组成。在此基础上采用多指标综合评价法研究了江苏各县（市）土地供给及非农开发需求程度。根据两者的组合特征,将全省分为四大适宜类型区,即高度适宜区、较高适宜区、中度适宜区和不适宜区,并提出了各类型区开发利用导向,对实现江苏省土地资源的合理有序开发、社会、经济、生态的统筹协调发展具有指导意义。 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.
