摘要
在沽源县红旗滩小流域陡坡地,选取地貌、土壤、植被等自然条件具有较强代表性的红泥滩村北山坡为研究地,设置未治理坡面径流小区、水平沟治理坡面径流小区、鱼鳞坑治理坡面径流小区3个观测小区。于2007~2009年的雨季连续监测、对比各径流小区的土壤流失量。结果表明:在坡度、坡向、植被盖度和降水特征等要素基本一致的条件下,水土保持措施效果由好到差依次是水平沟治理坡面径流小区、鱼鳞坑治理坡面径流小区、未治理坡面径流小区。坝缘山地陡坡地水土流失治理应提倡使用水平沟治理方式。
On the steep slope land of Hongqitan small watershed in Guyuan County,the northern slope of the Hongnitan Village was selected as the research area with stronger typical representation on natural conditions of the topography,soil,vegetation and so on.Three slope runoff observation plots were set up as follows:untreated slope runoff plot,treated slope runoff plot of level trench,treated slope runoff plot of fish-scale pit.The soil loss amount of each runoff plot rainy season during 2007-2009 was continuously monitored and compared.The monitoring data showed that under the basically consistent conditions of slope gradient,slope direction,vegetation coverage and precipitation characteristics,the effects of soil and water conservation measures in three runoff plots were as follows:treated slope runoff plot of level trench〉treated slope runoff plot of fish-scale pit〉untreated slope runoff plot.The government method of level trench should be used in water and soil loss government in steep slope land of the mountain areas on the edge of dam.
