Abstract根据观测资料,发现贡嘎山东坡从泸定到三营,降水有随海拔的增加而增加的趋势,而降水量的变差系数随海拔的增高反而降低,蒸发主要受温度的影响,其垂直递减梯度约为42.7 mm/100m。根据以往森林水文的研究成果,冰川河径流的季节变化应该比黄崩留沟小溪显著,但是观测结果恰恰相反,这可能是河流下切深度的不同和冰川补给造成的。本文认为,重碳酸钙型水是当地径流的主要类型。
Other AbstractOn the basis of the observational datum, the characters of the precipitation and evaporation aye analyzed.On the east slope of Mt.Gongga,form Luding County to Sanying,the precipitation increase with the elevation and the vertical grads of precipitation is about 75.3 mm per 100 m.The Non-glacial Stream originates form alpine forest region,whereas the Glacial River originates form the glacier of Hailuo Gully,and the forest area of the former is greater than that of the latter.According to study achievements of Forest Hydrology,the seasonal variety of runoff of Non-glacial Stream is more stable than that of Glacial River.but the observation datum not consistent with this.The cause that leads to this phenomenon is the incision depth of Glacial River is deeper than that of Non-glacial
Stream.
