【摘要】：针对黄河流域砒砂岩地区立地条件差、水土流失剧烈,以及砒砂岩孔隙率大、颗粒间黏性差而使常规的植物与工程治理措施难以有效实施的问题,探索了砒砂岩区水土流失治理的抗蚀促生与改性筑坝新技术,集成多措施多技术建立了综合治理模式,并开展了关键技术应用示范研究。研究表明:基于砒砂岩区水土流失规律提出的水土保持材料-工程-生物措施、坡面-沟道系统二元立体综合治理措施配置模式,治理效果明显;研发的抗蚀促生材料具有良好的抗蚀促生性能,具有减少土壤侵蚀、促进植物生长的作用;利用砒砂岩原岩改性材料建设的淤地坝,各项主要力学性能指标满足工程建设规范要求;研发的抗蚀促生复合生态材料措施可以作为我国生态环境极度脆弱区水土流失治理、生态建设的一条有效的新途径。
[Abstract]:In view of the poor site conditions, severe soil and water loss in the soft sandstone area of the Yellow River basin, and the large porosity and poor viscosity between particles, the conventional plant and engineering treatment measures are difficult to carry out effectively. In this paper, a new anti-erosion and modified damming technology for soil and water loss control in the arsenopyst area is explored. A comprehensive control model is established by integrating multi-measures and multi-technologies, and a demonstration study on the application of key technologies is carried out. The results show that the soil and water conservation material-engineering biological measures and the collocation model of two-dimensional comprehensive control measures of slope surface and channel system are put forward based on the rule of soil and water loss in the soft rock area, and the control effect is obvious. The developed anti-corrosion materials have good anti-erosion and growth-promoting properties, reduce soil erosion and promote plant growth. The main mechanical performance indexes meet the requirements of engineering construction specifications, and the developed measures of anti-corrosion and promoting growth compound ecological materials can be used as an effective new way to control soil and water loss and ecological construction in the extremely fragile areas of ecological environment in China.
