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4000m

，促进了节水农业的发展。

Abstract

Using the hight-analysis method founded by American geographer strahler A. N.

the charactors of erosive geomorphy of Dacha gully have been quantitavely computed and analysed. This conclusion could provide a scientific base for the optimum arrangement and comprehesive harness in the area. For the present，the general harness degree reachs 94.40，soil erosion has been basically controlled，and 4 OOOm' of the runoff can be harvested，it improved the developement of water saving agriculture.
