中文摘要：

对陕北多沙粗沙区乡村聚落中庭院、户间道路和户间空地的土壤侵蚀状况研究表明，户间道路侵蚀强度最强，其次为户间空地，庭院最小。进一步分析侵蚀泥沙中〉0．05mm粗颗粒和〈0．01mm细颗粒的含量与平均泥沙含量的关系说明，户间道路径流挟沙能力强，因而侵蚀强度最大；庭院水流平缓，挟沙能力最小，其侵蚀强度最小，而户间空地侵蚀强度居于二者之间。说明在加强治理黄土高原土壤侵蚀治理的同时，应特别重视乡村聚落户间道路的土壤侵蚀问题。

英文摘要：

The erosion intensities among courtyards, roads and open spaces between house and courtyards were analyzed. The results showed that the roads caused soil erosion easily than the courtyards and open spaces. The runoff on the roads had the strongest capacity to transport coarse grain 〉0.05mm, so had the biggest erosion intensity, but the runoff on the courtyards had the lest capacity to transport more coarse grain because of the flat gradient, so they transported more fine grain in sediment, and had lest erosion intensity. So during the control of soil erosion in Loess plateau, the soil erosion caused by the roads between house and courtyards should be paid more attention.
