| 摘 要： | 山区范围较之山地范围更具有模糊性和不确定性,同时山区在空间分布上更为连续和完整.在计算中国山地范围的基础上,运用地理信息系统的空间分析功能和统计模型中的聚类分析和多元回归分析技术,选择人口、土地利用、GDP、道路等社会经济因子,构建了计算山区范围的边缘生长模型,同时运用该模型计算出四川省的山区面积占总面积的76.77%,较之四川省的山地面积增长了3.21%,主要分布在川西及盆地周边区域.

| Abstract: | Mountain region (MR) is a more confusion and uncertainty terminology than mountains. It is defined by not only the physical characteristics (i.e. topography),but also some social-economic factors. A MR is a more continuous and integrative area than mountains at landscape scale. At the basis of the quantitative areas of the mountains in China,an edge growing model (EGM) was developed in this work to quantifying the MRs. The model utilized the spatial analysis functions in geographical information system (GIS... |
