中铝广西分公司赤泥堆场植被护坡试验研究

EXPERIMENTAL STUDY ON VEGETATION SLOPE PROTECTION FOR RED MUD DISPOSAL FIELD OF GUANGXI BRANCH OF CHALCO

针对赤泥坡面碱性高、坡度大、植被难度高的特点,试验研究了适合堆场条件的植被护坡工艺技术,试验选择了耐碱、速生的草本植物,实现边坡植被覆盖度80%以上,形成了赤泥筑坝与生态护坡基本同步进行的赤泥坝体安全管理和生态恢复模式。植物护坡有效地控制了坡面水土流失,迅速营造了坝坡景观,改善了坝区生态环境。

To direct at a high alkalinity, steep gradient, difficulties in vegetation of the red mud slope, this paper does repeated studies and experiments to produce successful vegetation process technology for the slope of red mud disposal field of Guangxi Branch of CHALCO. By simulation and field test, alkali resistance and rapid -grow several perennial herbs are selected, so the degree of vegetation coverage is more than 80 % of the experimental superficial extent. The model of security control and ecology building is formed, which has brought about the near synchronous schedule between damming and vegetation in project construction. Erosion control and landscape revival are rapidly realized. Ecology environment of the dam area is improved greatly.
