植被过滤带边坡水土流失综合治理技术研究

Study on Comprehensive Control Technology of Soil Erosion on Slope of Vegetation Filter Belt

水土流失与污染关系到水质治理,因此研究植被过滤带边坡水土流失综合治理技术十分必要。通过构建AnnAGNPS模型,模拟边坡水土流失及污染状态;根据水土流失和污染影响因子,选择与配置边坡植被过滤带,实现对边坡的综合治理。实验结果表明,面对不同流量时,按照5:12:3的填料配比,采用使植被过滤带综合治理技术进行治理,能够更好地保持水土,对污染物也有极好的削减效果。

Soil and water loss and pollution are related to water quality control,so the comprehensive control technology of soil and water loss of vegetation filter belt slope is studied.Through the construction of AnnAGNPS Model,the soil erosion and pollution status of the slope are simulated;according to the impact factors of soil erosion and pollution,the slope vegetation filter belt is selected and configured to realize the comprehensive treatment of the slope.Experimental results show that in the face of different flow rate,according to the ratio of 5:12:3,the comprehensive treatment technology of vegetation filter belt can better conserve water and soil,and has excellent reduction effect on pollutants.
