人工与自然恢复煤矸石山种子库特征

The Characteristics of Seed Bank Recovered by Artificial and Natural in Coal Gangue

采用野外调查和室内试验的方法,分析了人工恢复团柏煤矸石山和自然恢复的圣佛煤矸石山的地上植被和种子库的物种组成和相似性,结果表明,圣佛煤矸石山地上植被和种子库的丰富度和多样性均大于团柏,但两地的种子库中存在着耐贫瘠的植物种,对矿区植被的恢复具有一定的潜力.

Using the filed investigation and laboratory experiment methods, the composition species and similarity of vegetation and seed bank by artificial recovery in Tuanbai coal gangue and natural recovery in Shengfo coal gangue were analyzed. The results show that the richness and diversity index of aboveground vegetation in Shengfo are greater than that of in Tuanbai. Some species tol- erant of poor soil in seed bank could lontrrbute to aboveground regetation restoration. Some barren resistant species exist in two seed banks, which have a certain potential for the restoration of vegetation in the mining area.
