摘要
应用美国地理学家ＳｔｒａｈｌｅｒＡ。Ｎ。创立的高程积分法，对大岔沟的侵蚀形态特征进行了定量计算和分析研究，为大岔沟水土保持措施的优化配置和综合治理提供了科学依据。目前大岔沟治理度高达９４．０４％，基本上控制了水土流失，每年可拦蓄径流４０００ｍ３，促进了节水农业的发展。
Using the hight-analysis method founded by American geographer strahler A.N.,thecharactors of erosive geomorphy of Dacha gully have been quantitavely comptited and analysed。This conclusion could provide a scientific base for the optimum arrangement and comprehesiveharness in the area。For the present,the general harness degree reachs 94.4%,soil erosion hasbeen basically controlled,and 4 000m3 of the runoff can be harvested,it improved the develope-ment of water saving agriculture。
