黑河流域研究区边界

一、黑河流域盆地边界，系基于高精度的数字高程模型（DEM），利用GIS水文分析功能分析获得的，并参考了遥感影像、地形图、地面考察和前人的研究成果。黑河流域地表集水区范围约25.5万km2，南起祁连山中段，北部边界是蒙古国境内的戈壁阿尔泰山脉，西起马鬃山山区，东至雅布赖山。与传统的黑河流域范围相比，新的流域增加了巴...1. The boundary of the Heihe River Basin was derived via hydrological analysis using GIS tools based on high-resolution Digital Elevation Model (DEM), with reference to remote sensing imagery, topographic maps, field surveys and prior research findings. The Heihe River Basin has a surface catchment area of approximately 255,000 km², stretching from the middle segment of the Qilian Mountains in the south, with the Gobi Altai Mountains within the territory of Mongolia as its northern boundary, the Mazong Mountain area in the west and the Yabrai Mountains in the east. Compared with the traditional delineation of the Heihe River Basin, the new basin has added Ba...
