摘　　要：文章在GIS技术支持下,基于水文分析模型,通过DEM数据,结合山地综合分类模型,以重庆市万州区为例,对山地进行定量化分类研究,结果表明:以负地形洼地贡献区域作为山地相对高程的起算面,完全摆脱了人为因素的影响,解决了一直以来难以确定山地相对高度起算范围的难题;以负地形洼地深度作为山地相对高程是正确可行的,且能快速获取山地的相对高程;以山地表面积代替投影面积计算山地率更切合实际。Based on GIS, this paper studied on the quantified classification of mountainous region via hydrological analysis model by using the DEM, combining with integrated mountain classification model and taking Wanzhou in Chongqing as an example. The results showed that. it would help determine the mountainous relative height to regard the negative relief depressions as the base level; it would be correct and feasible that the depth of negative relief depressions is regarded as mountain relative height; it would be feasible that the surface area of mountain is substituted for the projected area for calculating the moun- tain rate.
