| 摘 要： | 对黄土丘陵沟壑区安塞水土保持试验站3种草本、3种灌木、3种乔木、1种农田共计10种植被类型径流小区进行径流和侵蚀泥沙观测，并分别分析其养分含量，研究黄土丘陵区不同植被类型水土保持功能及养分流失效应。结果表明，乔、灌、草植被类型的水土保持功能相对农田较好，在径流和土壤养分流失方面相对农田较少。因此，该地区要注意建设和恢复草、灌植被，使之尽快起到水土保持作用，近而减少土壤养分流失。

| Abstract: | The plot experiment of 10 vegetation types including 3 grass,3 shrub,3 arbor,and 1 farmland was carried out at Ansai Soil and Water Conservation Research Station in Hilly-gully region of Loess Plateau.Runoff and soil erosion data were observed.Runoff and nutrients content of sediment were analyzed in order to know the influence of different vegetation types on soil and water conservation function and nutrients loss.The obtained results show that the grass,shrub,and arbor vegetation types have much better so... |
