摘　　要：基于分辨率为90 m的SRTM-DEM数据,采用地理信息系统(GIS)技术,提取安徽省的地貌特征要素信息,并根据均值变点分析统计方法,定量地获取研究区域内的最佳地势起伏度的统计面积。根据中国地貌类型划分标准,将安徽省地貌类型划分为11种类型,其中分布较广的主要为中起伏中山、中起伏山地、小起伏山地、低海拔丘陵、低海拔台地、低海拔平原,并分别统计各类型面积。结果表明,该文研究方法能够定量、科学地对安徽省地貌形态进行分类。Based on the 90 m resolution SRTM DEM data,using geographic information system（ GIS） technology,this paper extracted the geomorphic elements of Anhui province. based on the mean change-point analysis method,the best access to quantitatively study area relief amplitude of statistical area. According to Chinese landscape classification standard,the landscape type in Anhui province was divided into 11 types,which has a wide distribution of mainly for the low relief mountain,intermediate relief mountain,low relief mountain,low altitude hills,low altitude platform,low altitude plain statistics of each type of area. Results show that this research method can quantitatively and scientifically classify morphology in Anhui province.
