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...

1. Boundaries of the Heihe River Basin: Derived via hydrological analysis in GIS based on high-resolution Digital Elevation Model (DEM), with reference to remote sensing images, topographic maps, field surveys and previous research findings. The surface catchment area of the Heihe River Basin is approximately 255,000 km², extending from the middle section of the Qilian Mountains in the south, with the northern boundary being the Gobi Altai Mountains within Mongolia, starting from the Mazongshan Mountainous Area in the west and reaching the Yabrai Mountains in the east. Compared with the traditional scope of the Heihe River Basin, the new basin has increased...
