Spatio-temporal variation of land and water resources benefit of north slope of Tianshan Mountains under the background of urbanization
天山北坡城镇化进程中的水土资源效益及其时空分异

Through Exploratory Spatial Data Analysis and its Global Moran's I index and Getis-Ord Gi* index,and coordinatied development degree function land & water resources benefit and urbanization level from 1995 to 2008 are analyzed systematically.Especially,the paper focused on agglomeration diffusion condition,its spatial pattern evolution and space linkage development effect of cold and hot spots.Some conclusions can be drawn as follows.Due to differences in oasis natural and geographical conditions,the spatio-temporal variations of urbanization and land & water resources benefit of north slope of Tianshan Mountains are different.(1) Counties with similar land use benefits show obvious spatial differentiation.The spatial structures in different years present dispersed pattern and keep stable constantly.(2) Agglomeration and dispersion of water resources benefits are not stable.Differences of changes are significant during the study years.(3) The pattern and path of spatio-temporal variation of urbanization and land & water resources benefits are different.Space linkage development effects are obviously different.Specific circumstances of development of oasis cities determine the spatial evolution of cold and hot spots of urbanization and land & water resources benefits are more sensitive than the development level themselves.
