为破解这一谜题,中国科学院等机构的研究团队将目光锁定在上Bhagirathi山谷——恒河重要源头的水文单元。 通过分析跨越半个世纪(1973-2024)的卫星影像和数字高程模型 (DEM),研究人员首次完整描绘出该区域11条冰川(包括著名的Gangotri冰川及其支流)从平衡态到失衡态的全景演变图谱。
针对印度北阿坎德邦Bhagirathi河流域频发的洪水灾害,研究人员结合遥感 (RS)、地理信息系统 (GIS)和层次分析法 (AHP),选取排水密度、降水、坡度等7个参数构建洪水灾害地图 (FHM),将研究区划分为5个风险等级,验证精度达66.8%。该成果为喜马拉雅山区洪水风险管理提供了科学依据。
