露天矿排土场土地复垦物种选择及生态监测研究(增刊)

露天矿外排土场是我国主要的环境破坏源之一。排土场复垦也就一直成为露天矿生态重建的主要目标,其中以植被重建最为关键,最终如何选择适宜物种成为每个复垦项目的核心问题。本文采用现场实验与数值分析相结合的方法,确定出符合山区生态环境的植物物种,并通过长期检测被选植被重建后的环境效益得出：根据区域土体及周边环境条件合理选择物种可以实现排土场生态重建目标；同样,选择适宜的物种可以减短植被恢复、适应过程,可尽早取得良好的经济价值和环境效益。

Study on the species selection and ecological monitoring of land reclamation in open pit dump

The waste-dump of open-pit mine is one of main environment damage sources. The land reclamation has always been the main goal of the ecological reconstruction of the open-pit mine, and how to select the suitable species is the core of each reclamation project and is the key link to vegetation reconstruction This study determine the plant species which are adapt to the location environment in mountain area with the method of field experiment and numerical analysis. And through long-term test of the environmental benefits of selected species we reach a conclusion that reasonable selection of species according to regional soil and surrounding environment conditions can achieve the goal of ecological restoration of soil dump and can shorten the adaptation process of vegetation restoration and can obtain good economic value and environmental benefits in advance.
