江苏省土地利用结构空间分异研究

采用最小方差法研究江苏省各县(市)的土地利用结构类型及其空间分异特征.结果表明:全省可以分成七大土地利用结构类型区,即耕地未利用地均衡主导类型区、耕地主导建设用地为辅类型区、耕地建设用地未利用地均衡主导类型区、耕地主导建设用地其它农用地为辅类型区、耕地主导建设用地未利用地为辅类型区、耕地建设用地主导均衡类型区和耕地主导均衡类型区等.这不仅揭示了江苏省土地利用的空间分异规律,也为全省土地资源利用战略的制定、土地资源的可持续利用、统筹社会经济生态之间以及区域之间协调发展提供了依据.

Spatial Differentiation of Land Use Structure in Jiangsu Province

Adopting the method of Least Square Error, this paper analyes the land use structure characteristic of each county or city in Jiangsu Province. Based on the results,Jiangsu Province can be divided into seven land use structure types. The first one is the type with the balanced dominant land use types of arable land and unused land, the second one is the type with the dominant land use type of arable land supplemented by construction land, the third one is the type with the balanced dominant land use types of arable land, construction land and unused land, the fourth one is the type with the dominant land use type of arable land supplemented by construction land and other agricultural land, the fifth one is the type with the dominant land use type of arable land supplemented by construction land and unused land, the sixth one is the proportional type with the dominant land use types of arable land and construction land, the seventh one is the proportional type with the dominant land use type of arable land. Lastly, it presents the distribution characteristics and general situation of land use structure status respectively, which offers some bases for making land use strategies, sustainable land use,coordinating the harmonious development among regions as well as social economy and ecology.
