摘要
陕西省略阳县在20 a的"长治"工程实践中,探索出适合小流域沟道治理的生物砂堤沟道治理技术。介绍了实施生物砂堤技术的方法、步骤及其技术要点。根据水土流失规律,指出了生物砂堤在水土流失防治体系中的作用。通过与浆砌河堤在工程量及投劳耗费方面的比较,得出生物砂堤具有节约成本的优势,值得在小流域综合治理中应用推广。
During 20 years′ practice of major control engineering of soil and water conservation in upper and middle Yangtze River,Lueyang County government probes out gully control technology using biological sand barrier which is suitable for small basins.We introduce the method,steps and key points of biological sand barrier technology and point out the role of biological sand barrier in soil-water loss prevention system according to the loss laws.The comparison of grouted embankment and biological sand barrier in work quantity and manpower cost shows that it is superior to grouted embankment in cost savings.
