摘要
孤山川属黄河一级支流,全长79.4 km,流域面积1272 km2。流域内地貌为沙盖黄土丘陵沟壑、黄土丘陵沟壑,基岩沟谷丘陵与河流阶地等,岩土侵蚀类型有五:一是风力侵蚀—风沙侵蚀;二是降雨对谷坡面的面状冲刷—坡面侵蚀;三是地表径流对谷底的侧蚀—沟谷侵蚀;四是滑塌对谷坡坡体的破坏—重力侵蚀;五是人力侵蚀。本文根据上述侵蚀类型提出了不同的防治对策。
The Gushanchuan River, located in Fugu county of Shaanxi province, is a grade-I tribu- tary of the Yellow River. It has a total length of 79. 4kin and a drainage area of 1, 272 km2, in which sand cover in loess hilly-gully region, loess hilly-gully region, bedrock valley hills and stream terrace are included. The types of geotechnical erosion include： 1 ） wind abrasion-wind bearing sand abrasion; 2） surface erosion of valley and slope-erosion of sloping surfaces; 3 ） lateral erosion by surface runoff-- gully erosion; 4） destruction d slide and collapse in slopes-gravity erosion; and 5） human erosion. Based on the types of erosion, some prevention and cure recommended in this paper..
