摘　　要：以径流小区的观测资料为依据，对晋西黄土区坡面水土保持林地降雨、径流、泥沙进行了分析，该地区产生地表径流的基本降雨条件为最大雨强在１０ｍｍ／ｈ以上，降雨量在１０ｍｍ以上；该地区能够造成土壤侵蚀的主要降雨形式为降雨量在３０ｍｍ以上的降雨。该文还建立了计算地表径流量的回归模型。Based on the data of runoff plots, runoff and sediment yiekls were analyzed in theforests of soil and water conservation in the Loess region, west of Shanxi province,It was sug-gested that surface runoff was caused only under the condition that the maximum rainfall intensi-ty was more than 10mm per hour with precipitation over 10mm. Soil erosion was preduced underthe condition of precipitation more than 30mm. A regressive medel was also put forward in thispaper.

关 键 词：地表径流 土壤侵蚀 水土保持林 晋西黄土区
