Cold region steep slope riparian buffer zone construction method based on non-point source pollution blocking
The invention relates to a cold region steep slope riparian buffer zone construction method based on non-point source pollution blocking, and belongs to the technical field of river non-point source pollution treatment in cold regions. At the gradient gt; impurities on the surface of a base of the 50% steep slope riparian buffer zone are removed, slope leveling is carried out, and a slope matrix is made firm; the method comprises the steps that living arbor stumps are wedged into the slope bottom of a steep slope at the position, extending towards the water surface by 0.5-1 m, of the slope top, the adjacent stumps are fixed through iron gauze, and a willow pile sewage interception area is arranged; filling gravels and pumice stones into high-density polyethylene mesh cloth according to a ratio of 1: 3, wrapping the high-density polyethylene mesh cloth with willow branches, and fixing the willow branches with iron wires at the heads and tails of the willow branches to prepare willow branch bundles; willow branches are vertically placed between the willow piles and the vertical face of the bank slope; shrubs and arbors are planted close to the willow branch bundle arrangement area to serve as an arbor and shrub interception area; herbaceous plants are planted close to the arbor and shrub interception area to serve as a herbaceous retention area. The method can be used for repairing and preparing the steep slope interception non-point source pollution riparian buffer zone in the cold region.
基于面源污染阻断的寒冷地区急陡坡河岸缓冲带构建方法，属于寒冷地区治理河流面源污染技术领域。在坡度>50％的急陡坡河岸缓冲带清除基底表面杂物，并进行坡面平整，使其坡面基质牢固；在坡顶向水面延伸0.5～1m处，向急陡坡坡底处，楔入乔木活体树桩，相邻树桩通过铁丝网固定，设置柳木桩截污区；将高密度聚乙烯网布装入1:3比例砾石和浮石，并用柳枝包裹，用铁丝在柳枝头尾处固定，制备柳枝捆；将柳枝垂直放置于柳木桩与岸坡立面之间；紧邻柳枝捆布设区种植灌木和乔木作为乔灌截留区；紧邻乔灌截留区种植草本植物作为草本滞留区。本发明可用于寒冷地区急陡坡截留面源污染河岸缓冲带的修复和制备。
