Ecological restoration and soil matrix improvement method for sand excavation waste side slope
The invention discloses an ecological restoration and soil matrix improvement method for a sand excavation waste side slope, and belongs to the technical field of ecological restoration. The ecological restoration and soil matrix improvement method comprises the following steps of accurately measuring the waste side slope, marking out a to-be-treated area of the sand excavation waste side slope, and removing surface pollutants in the to-be-treated area till clean surface soft sand soil is exposed; digging the surface soft sand soil to be loose after the surface pollutants are removed; and fixing a base layer of the sand soil slope surface. According to the ecological restoration and soil matrix improvement method, the sand soil slope surface is fixed through anchor rods and a composite material net, the matrix layer is laid, the problem that vegetation cannot grow due to slope instability and water and soil loss caused by sand excavation is solved, riverway desilting river mud, pond mud and other clay are used on site and are mixed with crude sand land, and small-specification nursery stocks and nitrogen-fixing plants are screened, so that the soil fertility is increased, the sand soil performance is improved, the problem that the surface sand soil special for an abandoned sand excavation field is loose and lacks fertility and follow-up potential soil texture is solved, and the long-term vegetation effect is increased.
本发明公开了一种采砂废弃边坡生态修复及土壤基质改良方法，属于生态修复技术领域，包括如下步骤：对废弃边坡进行精准测量，划出采砂废弃边坡待治理区域，去除待治理区域的地表污染物，直至露出干净的地表松软砂地土；将地表污染物去除后，刨松地表松软砂地土；固定砂土坡面的基层；本发明通过利用锚杆、复合材料网固定砂土坡面，并铺设好基质层，解决了采砂作业形成的边坡失稳、水土流失而导致的植被无法生长的问题，通过就地使用河道清淤河泥、塘泥等黏土掺和原砂地，筛选偏小规格苗木及固氮植物，来增加土壤肥力，改善砂土性能，解决了废弃采砂场特有的表层砂质土松散、缺乏肥力及后续潜在土质问题，提高长期植被效果。
