基于AHP法黑龙江多宝山铜业矿山排土场植物筛选

Plant Screening in Dumping Site of Duobaoshan Copper Mine in Heilongjiang Based on AHP Method

以黑龙江多宝山铜业矿山排土场边坡植被恢复和景观重建的植被筛选为目的,在对矿区本底植物调查、黑龙江省栽培植物调查的基础上,运用层次分析法(analytic hierarchy process,AHP)构建生态适应性、生态防护性、绿化效果、经济性4个方面10个具体指标的筛选评价体系,对74种植物进行权重排序,最终筛选出适用于多宝山铜业矿山排土场植被修复的乔木、灌木、草本共计20种,为矿山排土场生态环境的改善和景观重建提供了植物选择,也为我国寒区其他矿山排土场生态修复植物的选择提供一些实践借鉴。

In order to select plant for vegetation restoration and landscape reconstruction on the side slope ofthe dump in Heilongjiang Duobaoshan Copper Mine,the investigation of background plants in the mining areaand the investigation of cultivated plants in Heilongjiang Province was based on,and the analytic hierarchyprocess(AHP)was used.The results showed that a screening evaluation system was constructed including 10 specific indicators in 4 aspects of ecological adaptability,ecological protection,greening effect,and economicefficiency,and 74 plants were sorted by weight,and finally the dumping ground suitable for DuobaoshanCopper Mine were screened out totally of 20 species of trees,shrubs,and herbs for vegetation restoration,which would provide plant for the improving the ecological environment of mine dumps and landscapereconstruction,and for practical reference for the selection of ecological restoration for other mine dumps incold regions of China.
