- 摘要:
- 以重庆缙云山4种不同植被类型坡面为研究对象，对2002年降雨和地表产流实测值进行对比分析，结果表明：三峡库区4种坡面在相同的降雨条件下，产流量依次为：混交林地（65.18mm）>毛竹林地（64.72mm）>灌木林地（30.52mm）>阔叶林（18.71mm），并且产流量集中分布在4-9月，其中阔叶林的产流量为4种植被类型坡面中最低，表明阔叶林相对于其它坡面在调节径流方面的作用最大；地表特性各因素与产流量间的灰关联度大小依次为：土层厚度>枯落物量>林分郁闭度>坡度，地表特性各因素对产流量的影响均较大，其中土层厚度对产流量的影响最大，而坡度对产流量的影响最小；产流量与降雨量都表现出较好的线性相关关关系，且土层厚度直接影响着起始产流雨量。
- Abstract:
- Four different vegetation stand slopes in Jinyun Mountain in Chongqing city were studied.By contrasting the rainfall and the surface runoff in 2002, the results showed that, with the same precipitation, the amount of runoff in the mixed forest was the maximum (65.18 mm), the second was the Phyllostachys pubescens forest (64.72 mm), the third was the shrub forest (30.52 mm), the fourth was the broad-leaved forest (18.71 mm).The amount of runoff concent rated mainly from April to September.In this period the amount of runoff in the broad-leaved forest was the minimum in all the vegetation stand slope.The results showed that effects of the broad-leaved forest on the regulation of slopes runoff were the maximum.Between all the surface conditions and the amount of runoff grey relation of soil thickness was the maximum, the second was litter amount, the third was canopy closure extent, the fourth was slope.Effects of all the surface conditions on the amount of runoff were all great.Effects of soil thickness on the amount of runoff were the maximum, and effects of slope were the minimum.The correlativity between the amount of rainfall and the amount of runoff was remarkable, and soil thickness directly affected the amount of rainfall of initiative runoff.
