铺地黍在铅锌矿冶工业区应用研究

Applied Study of Panicum Repens in the Industry Area of Lead-Zinc Mining and Metallurgy

由于金属冶炼生产导致冶炼厂下风向形成了大面积的工业裸地,其特点是土壤板结、重金属含量高、极度酸化与贫瘠。因而,依赖于植被的自然恢复极其困难。通过在韶关冶炼厂工业区距污染源远近不同的地段建立以铺地黍作为地被植物的4个实验小区,实验结果表明铺地黍(Panicum Repens)既具有抗污染性能,又具有较好的固定表土的性能。旨在为类似生态环境治理的同行提供参考。

A large industry bare area is formed in the downwind of smelter caused by metal smelting production, with feature of soil sealing, high content of heavy metal, utmost acidification and barren, Therefore, it is rather difficult for vegetation to recover natu- rally. Through the test in the 4 experimental plots in which plant Panicum Repens as vegetation set in various section of area far and near from pollution sources in the industry area of Shaoguan Smelter, it is indicated that Panicum Repens is provided with both features of anti pollution and surface soil fixation. This paper aims to offer reference to the treatment of similar ecology environment.
