沙棘“柔性坝”对砒砂岩区生态调控效应试验研究

Experimental Research on the Effects of the Seabuckthorn Flexible Dam on Eco-regulation in Soft Rock Region

通过沙棘"柔性坝"野外原型试验,从土壤有机质、含水量、植被种类及覆盖度、动物种类及数量等方面研究了沙棘"柔性坝"对砒砂岩区土壤改良效应和生物群落恢复效应,研究结果表明:沙棘"柔性坝"显著地提高了砒砂岩区土壤肥力,涵养了水源,使得濒临破坏的生态环境得到了较大程度的恢复。

Through the experiment of sea buckthorn flexible dam in the field,from the aspects of soil organic matter,moisture content,vegetation type,coverage and the number of animal species and so on,the paper researched the effects of sea buck thorn flexible dam to the soil improvement and the recoreryof biological community.The results showed that the sea buckthorn flexible dam obriously increased the soil fertility,protected the water source in the soft rock area and also greatly recovered the ecological environment.
