Ecological restoration structure and restoration method for abrupt slope of abandoned quarry
The invention discloses an ecological restoration structure for an abrupt slope of an abandoned quarry. The ecological restoration structure is characterized in that a plurality of stepped reverse slope table tops are arranged on the abrupt slope of the abandoned quarry, the outer parts of the reverse slope table tops are high, the inner parts of the reverse slope table tops are low, the table tops are arranged in a reverse slope form inclining towards the inner sides, and an original slope surface is formed between the upper and lower adjacent reverse slope table tops. By adopting the reverse slope table tops, the slope length can be shortened, the original slope surface can be cut off, the runoff speed of the slope surface can be reduced, the radial flow kinetic energy can be reduced, so that the water and soil loss of the slope surface can be reduced, the shape structure of the reverse slope table tops changes the topographic condition of the original slope surface, a better site condition is created for slope surface greening, climbing plants can be planted on the slope surface and climb upwards to cover the original slope surface, so that the area suitable for forest is increased; U-shaped drainage ditches are arranged, rainfall runoff on the slope surface can be drained in time, and meanwhile, multiple sand settling basins are arranged in longitudinal drainage to reduce loss of silt on the slope surface; and the overall structure is reasonable, and the ecological environment of the abrupt slope of the abandoned quarry can be restored in an accelerated mode.
本发明公开一种废弃采石场陡坡生态修复结构，废弃采石场的陡坡上设置有阶梯式的若干级反坡台面，反坡台面外高内低，台面设置为向内侧倾斜的反坡形式，而上下相邻的反坡台面之间构成原始坡面。本发明采用反坡台面，可以将坡长截短，截断原始坡面，减缓坡面产流速度，降低径流动能，从而可以减少坡面水土流失，并且反坡台面的形状结构改变了原始坡面的地形条件，为坡面绿化创造了一个更好的立地条件，坡面上又可种植攀藤类植物，向上攀爬覆盖原始坡面，增加宜林面积；本发明设置U型排水沟，可将坡面上的降雨径流及时排出，同时纵向排水中设置多处沉沙池，以减少坡面泥沙的流失；整体结构合理，有加速修复废弃采石场陡坡边坡的生态环境。
