滇中高原山地4种人工群落径流量和土壤流失量的研究
摘要
基于连续5年的定位观测
研究了滇中高原4种典型人工群落的径流与侵蚀特征。结果表明:区域降雨量的季节分配不均
湿季(6~10月)降雨量占全年的86.64%
降雨量主要由大于10 mm以上的降雨带来
且降雨强度大部分小于5 mm/h。与荒地相比
林地的水土保持效益显著。试验小流域的地表径流量与降水量密切相关
土壤流失量主要决定于地表径流量
其次是降水量。
Abstract
According to the 5 years' observation
the study on the precipitation and runoff of man-made plant community in central Yunnan Plateau was conducted
and some results are as follows: the season distribution of precipitation in the area is uneven
the rainfall of wet season account for 86.64% of the year totals
the precipitation is mainly brought by rainfall with more than 10mm
and most of the rainfall intensities are less than 5 mm/h.Compared to wasteland
the forest land have a notable effect of soil and water conservation.In trial watershed
the runoff has a highly correlation with precipitation
and soil erosion is determined by runoff primarily
