中巴经济走廊及天山山脉地貌类型250m分辨率数据集（参考时段2000年与2016-2011）

本数据集是中巴经济走廊及天山山脉地貌类型250m分辨率数据集，覆盖范围为中巴经济走廊及天山山脉。本数据集将地貌类型分为10大类，分别为Fat，peak or summit，ridge，shoulder，spur，slope，hollow，footslope，valley，pit or depression。本区域内十类地貌类型均有分布，其中以slope，hollow，spur三大类地貌类型为主，分别占38.6%，16.1%，15.8%，三类地貌类型累计占本区域面积的70.5%。本数据集中根据2000年2月的SRTM3 DEM 与2006年1月-2011年4月的AW3D DEM数据进行分析得出，采用WGS84 地理坐标（Geographic Coordinate System），能够为了解中巴经济走廊及天山山脉地貌类型分布提供依据。This is a 250-meter-resolution geomorphic type dataset covering the China-Pakistan Economic Corridor and the Tianshan Mountains. It classifies geomorphic types into 10 categories: Fat, peak or summit, ridge, shoulder, spur, slope, hollow, footslope, valley, and pit or depression. All 10 geomorphic types are present in this region, with slope, hollow and spur being the dominant ones, accounting for 38.6%, 16.1% and 15.8% respectively, and their combined area accounts for 70.5% of the total study area. This dataset was developed through analysis of SRTM3 DEM data from February 2000 and AW3D DEM data from January 2006 to April 2011, and uses the WGS84 Geographic Coordinate System. It can serve as a basis for understanding the distribution of geomorphic types across the China-Pakistan Economic Corridor and the Tianshan Mountains.
