摘要:
植被分布格局对其水土保持功能有重要影响.植被斑块与裸地斑块的不同组合配置对调控坡面径流侵蚀的作用不同.本文通过野外人工模拟降雨,对黄土丘陵区演替初期茵陈蒿(Artemisiacapillaries)群落不同格局下的侵蚀产沙特征进行了定量分析研究.结果表明：在2.43mm/min雨强下,盖度相同组合不同,分布均匀的小斑块格局(B)比大斑块格局(C)的减流量高,但减沙效益降低.与裸地小区相比,格局B、C减流效益分别为14.7%、9.5%,减沙效益分别为36.14%和63.86%.坡面累计产流量随降雨历时逐渐增加,且二者呈线性相关.累计产沙量随降雨历时先增后减,表现为二次函数关系.累计产沙量与累计产流量之间也为二次函数,即随着径流量的增加,累计产沙量先增加后减少.
Abstract:
Vegetation pattern has a great affection on its soil conservation function.Different combination of vegetation and bare land play a different role in regulating runoff and sediment yield.By simulated rainfall in the field,an experiment of runoff and sediment production and its characteristics was conducted in various Artemisia capillaries community distribution patterns at preliminary succession stages in Loess Hilly Gully Region.The results showed that under the same rainfall intensity of 2.43 mm/min and vegetation coverage,the runoff-reducing benefit of pattern B uniformly distributed by small plaque was greater than pattern C distributed by large plaque.Whereas,the sediment-reducing benefit was smaller.Compared to bare plot,the runoff in pattern B and C was decreased by 14.7% and 9.5%,and the sediment reduced of 36.14%,63.86% respectively.The accumulative runoff of the band-shaped plot increased with the rainfall duration with a linear relation.The accumulated sediment yield increased with rainfall time and then gradually decreased,such relation could be described by quadratic function.Also,the initial sediment yield was increased with runoff volume,then decreased.The changes in accumulative sediment yield with runoff was also conformed binomial function.
