通过探讨歪头山尾矿坝的治理,用最经济的手段达到最理想的目标。尾矿坝采用分段治理,即分段用植物固定坝面,解决扬尘、雨水冲刷拉沟等问题,在此主张一:底部固定坝面用沙棘进行固定。原因是:沙棘是阳性树种,在疏林下生长,这为以后植树造林创造前提。成林后,抗冲刷性强,而且它不怕沙埋,固沙性强,能够阻拦洪水下泄、拦截泥沙,提高沟道侵蚀基准面。最后是沙棘的固氮能力很强,能够为其他植物的生长提供养分。主张二:顶部用植生袋法用藤蔓植物攀爬固定上部悬浮物,即蔓生植物。通过分段治理,梯次推进,从而达到固定、开发、环保等多重目的。
By exploring the treatment of Waitoushang tailing dam, the most economical means are used to achieve the best goal. Tailings dam using sub-governance, that is, the use of plant fixed dam surface, to solve the dust, rain erosion ditch and other issues, in this claim a: the bottom of the fixed seabed with seabuckthorn fixed. The reason is: seabuckthorn is a positive species, grow under the sparse forest, which creates the premise for afforestation. Into the forest, anti-scouring strong, and it is not afraid of sand buried, strong sand-fixing, to prevent floods, intercept silt, and improve the channel erosion datum. Finally, seabuckthorn has a strong ability to fix nitrogen and can provide nutrients for the growth of other plants. Advocacy two: top with bagging method of climbing with vine plant climbing suspended solids, that is, man-made plants. Through the sub-governance, promotion of echelon, so as to achieve the fixed, development, environmental protection and other multiple purposes.
