采用人工模拟降雨的方法研究了河北省片麻岩山区坡地的产流特征，结果表明：在人工降雨条件下，水分蒸散量与气温有关，蒸散率为５％～１８％；土壤入渗速率与土地利用状况关系紧密，土壤入渗率油松＞刺槐＞荆条灌木林＞荒坡草地，隔坡沟状梯田＞鱼鳞坑＞荒坡草地；坡面工程措施和造林可减小径流系数，能有效地拦蓄地表径流。
The artificial rainfall simulation was used to study the characteristics of runoff generation on the slope in the gneissic mountainous area of Hebei Province. The results show that the evapotranspiration is about 5% ~ 18% under the artificial rainfall conditions. The soil infiltration rate and The relationship between land use and land use was close. The soil infiltration rate was Pinus tabulaeformis> Robinia pseudoacacia> Vitex negundo forest> barren grassland, gully terraces> fish scale pit> barren grassland; slope engineering measures and afforestation could reduce the runoff coefficient and be effective Prevent surface runoff.
