摘要
以重建采矿废弃地的人工———半人工生态系统为目的 ,于 1998年 7月对安太堡露天煤矿 1991～ 1998年复垦的 480hm2 土地上野生植物侵入的种类进行调查 ,同时分析了 77个样地上不同野生植物侵入的频度等状况 。
In order to reconstruct controlled or semi -controlled ecological system,wild plant species which had intruded into 480 hm\+2 of the reclaimated land at An Taibu open-cast coal mine during 1991 to 1998 were investigated. On the basis of analyzing the frequency of different wild plant species on the 77 sample areas,the author put forward the problems to be studied further.
