气候和下垫面驱动下典型植物措施对径流和侵蚀的水土保持效应
Soil and water conservation effects of typical plant measures on runoff and erosion driven by climate and underlying surface
[目的]典型植物措施气候(降雨量特征)、下垫面(坡度、前期土壤含水量)等综合对径流、侵蚀的定量分析仍然是半干旱地区具有挑战性的研究,在自然降雨条件下,定位监测了 1987-2019年中国甘肃省的安家沟小流域不同措施(乔木林地、灌木林地、人工草地、天然草地和农地)不同坡度(10°、15°、20°)径流小区的降雨特征、前期土壤含水量、植被覆盖度、径流、侵蚀等。[方法]运用逐步回归模型和路径分析法,建立了主要驱动因子对径流量、土壤侵蚀最优评估模型,其评…查看全部>>
[Objective]The comprehensive quantitative analysis of runoff and erosion under specific climate(precipitation characteristics)and underlying surface conditions(slope,antecedent soil moisture)with different plant measures remains a challenging research topic in semi-arid regions.With a dataset from the Anjiagou watershed in Gansu Province,China,we conducted a comprehensive study on the soil and water erosion patterns under different plant measures.The researc…查看全部>>
