中国土地利用/土地覆盖的多尺度空间分布特征分析

Multi-scale Spatial Characterization of Land Use/Land Cover in China

研究了我国土地利用影响因素及其空间规模相关性，采用数理统计与ＧＩＳ手段从多个规模尺度上探讨了我 国土地利用的空间分布特征。其结果对全国以及各级政府进行土地利用规划、制定相应的土地开发与利用政策等 具有一定的参考意义。

This paper analyzed the determining factors Of land use and its spatial dependency in China, and through statistical and multi-scale GIS techniques investigated the spatial patterns of land use. Correlation and regression analysis was used to identify the most important explanatory variables from a large set of candidate determining factors. We found that the distribution of all land use types in China will be best described by a combination of different biophysical and socio-economic factors. Specific attention was given to the influence of scale and the spatial distribution of arable land. The results will provide some reference for the land use planning and spicy-making of sustainable utilization of land resources.
