摘要

水土流失不仅会造成江河湖库泥沙淤积,而且是面源污染的重要来源。水土保持植物措施和工程措施对水土流失及面源污染具有防控效果。通过径流小区的定位观测试验,定量研究了水平竹节沟、水平台地、前埂后沟与乔灌草、植物篱、梯壁植草等水土保持工程、植物措施的综合防控效应。2010—2012年的试验结果表明:相对于荒地,乔+灌+草+水平竹节沟、油茶+水平竹节沟、油茶+植物篱、脐橙+水平台地+梯壁植草的减流率分别为68.86%、84.05%、35.59%、78.35%,减沙率分别为76.47%、81.96%、26.28%、79.66%,总氮拦截率为49.75%～61.91%,总磷拦截率在98%以上。
        Soil and water loss not only causes sedimentation,but also is an important source of non-point source pollution. Plants measures and engineering measures of soil and water conservation have preventive and control effect on soil and water loss and non-point source pollution. The paper quantitatively studied the comprehensive prevention and control effect of plants and engineering measures,including bamboo-type contour trench,level-reversed bench,ridge in front and ditch behind,arbor-shrub-grass,living hedges and planting grass on terrace wall through local observation experiment of runoff plots. The outcomes of three-year tests( from 2010 to 2012) show that a) comparing with the wasteland,the runoff reduction rates of the arbor + shrub + grass + bamboo-type contour trench measure,oil-tea camellia + bamboo-type contour trench measure,oil-tea camellia + living hedges measure and navel orange + level-reversed bench + planting grass on terrace wall measure are 68.86%,84.05%,35.59% and 78.35% respectively; b) the sediment reduction rates are 76.47%,81.96%,26.28% and 79.66% respectively and; c) the total nitrogen interception rate is 49. 75%-61. 91% and the total phosphorus interception rate is more than 98%.
