| 摘 要： | 通过调查安徽钢陵五公里铜矿废弃地的植被及植物区系，结果显示：该地定居植物49种，隶属22科46属，其中禾本科12种、菊科8种、豆科4科、蓼科4种。废弃地据复垦情况分为复垦边缘区、复垦中心区和未复垦区，定居植物在三区内形成4种相对稳定的演替群落类型：狗牙根 白茅植物群落，白茅 三叶草 狗牙根植物群落，天蓝苜蓿 三叶草植物群落和小飞蓬 一年蓬植物群落。计算分析各群落的多样性指数和均匀度指数，并计算综合优势比，找出群落的优势植物。

| Abstract: | Investigation was conducted on the vegetation and flora of the copper tail mining wasteland in Tongling(Wugongli),Anhui.Total 49 plant species belonging to 46 genuses and 22 families,were found.Among these species,there were 12 ones of Gramineae Poaceae,8 of Asteraceae,Compositae,4 of Fabaceae,Papilionaceae and 4 of Polygonaceae.According to rehabilitation,the wasteland was divided into 3 regions:marginal region of rehabilitation,central region of rehabilitation and unrehabilitating region.The vegeration formed 4 types of relatively stable community:Cynodon dactylon-Imperata cylindrica community, Imperata cylindrica-Trifolium pratense- Cynodon dactylon community,Medicago lupulina- Trifolium pratense community and Conyza canadensis-Erigeron annuus community.The diversity index and the evenness index of every plant community were calculated and the summed dominance ratio of every plant was analyzde to find out dominant species in each of the communities.Some suggestions were given about vegetation rehabilitation in mining area. |
