四川省黑水县冰川水资源的特征与评价

Features and Evaluation of Glaciation Landscape Reasources in Heishui County,Sichuan Province

首次专门对四川黑水县羊拱山脉等地的现代冰川水资源、第四纪古冰川以及相应的景观地貌环境进行了科学考察。境内共发育分布现代冰川 19条 ,形态类型有悬冰川、坡面冰川、冰斗悬冰川、冰斗山谷冰川 ,总面积达 6 .0 4km2 ,冰储量为 0 .1736km3 。值得注意的是在海拔 5 0 0 0m附近背阴处发现零星的婴儿冰川 (BabyGlacier)分布。这对当地区域气候环境的变化具有重要的窗口监测作用。打古冰川谷地上源的古冰蚀、冰碛湖泊星罗棋布 ,达数百个之多 ,这为当地未来的生态、环境科学探险。

The expedition of glaciations in Heishui County,Sichuan Province has been first carried out in August 2001.There are 19 glaciers with area of 6.04km 2 and storage of 0.1736km 3.Its notable that two'baby glaciers'have been found in the east slope of Yanggong Mountain.These new small glaciers are very important for the observation of local environment changes.These are also hundreds of ancient morain lakes and other various glaciation landscape in the upper reach of Dagu valley.That is a very good foundation to develop scientific expedition and tourism in this region.
