冶金矿山废弃地生态恢复植物优选试验研究

Study on Plant Optimization of Ecological Restoration of Metallurgical Mine Wasteland

选取南方典型冶金矿山凹山排土场作为试点,采用水土保持工程措施和植物措施相结合的方法进行生态恢复,首先在室内通过盆栽试验的方法进行物种筛选,然后在所选排土场进行现场小区试验。现场小区试验结果表明,筛选的紫穗槐、合欢、百喜草、狗牙根等均生长良好,可作为该排土场及其它类似冶金矿山废弃生态恢复的首选植物品种。

Taking the topical metal mine in south of China,Washan dump,as an example,the combination of the water and soil conversation and the plant restoration were present to realize the ecological restoration.Potted experiments of Species selection were first carried out to select suitable plants,and then these plants were planted in the mining wasteland.The results showed that these plants selected in the potted experiments such as Amorpha,Albizzia,Bahia grass,Bermuda grass grew well,and can be used as the optimal plants species in vegetation restoration for similar dump and mine.
