基于最小方差法的土地利用空间分异分析——以吉林省为例

Analysis of Land Use Spatial Differentiation Using the Minimum Variance Method

利用最小方差法将吉林省各县(市)的土地利用结构分为九大类型,包括耕园地主导类型区、林草地主导类型区、耕园地为主林草地为辅类型区、林草地为主耕园地为辅类型区、耕园地为主建设用地林草地为辅类型区、耕园地为主林草地未利用地为辅类型区、未利用地为主耕园地林草地为辅类型区、林草地为主耕园地未利用地为辅类型区和林草地主导其他地类均衡类型区,揭示了吉林省土地利用的空间规律,为吉林省土地资源利用战略的制定、农业区的规划发展,以及社会经济与生态环境的协调发展提供科学依据。

Using the minimum variance method,the land use structure of counties（cities） in Jilin Province was classified into 9 types.The nine types of land use structure are farm/garden oriented zone,forest/grass oriented zone,farm/garden oriented and grass supplemented zone,forest/grass oriented and farm/garden supplemented zone,farm/garden oriented and constructed land/forest/grass supplemented zone,farm/garden oriented and grass/unused land supplemented zone,unused land oriented and farm/garden/forest/grass supplemented zone,forest/grass oriented and farm/garden/unused land supplemented zone,forest/grass oriented and other land use types equally supplemented zone.The land use spatial rules were revealed,which will provide scientific basis for making strategies for land resource use,zoning and developing agriculture,balancing the development of socio-economic and eco-environment in Jilin Province.
