浙江江山采石露矿堆土生态修复技术及植被恢复效果研究

采石场是典型的退化生态系统,需要进行生态修复。以浙江省江山市老虎山景区为例,原采石场地通过堆土重建适宜植物生长的生境,进行植被恢复,经过15年的人工干预与自然恢复相结合,从栽植的乔木单层林发展成乔灌草复合的植物群落。经调查维管束植物49科97属106种,其中人工栽培植物35种,仅占总种数的33.02%,而自生植物高达71种,占总种数的66.98%。尤其是自然恢复的乔木达10种,且绝大多数为乡土树种,植物多样性明显提高,取得较好的生态景观效应。

Quarry is a typical degraded ecosystem that needs ecological restoration.In this article the Laohu Mountain Scenic Spot in Jiangshan City,Zhejiang Province is taken as a research example.By piling up soil,this scenic spot has reconstructed an environment suitable for plant growth and carried out vegetation reclamation.In addition,after 15 years of practice combining artificial interference with natural restoration,this scenic spot has evolved from a single-layered forest of trees into a complex community of trees,shrubs and grasses.It has been found that there are 106 species of vascular plants in 49 families and 97 genera.Among them,there are 35 species of artificially cultivated plants,accounting for 33.02%of the total species,and 71 species of volunteer plants,accounting for 66.98%of the total species,especially naturally restored trees,which account for 10 species,most of which are native tree species.The plant diversity in this scenic spot has been significantly improved and a better ecological landscape effect has been achieved.
