摘要
矿山生态修复工程能够对受损矿山进行生态系统重建,有利于矿山生态环境保护.本文以北京首云矿山的生态修复地为研究区,通过团粒喷播生态修复技术在受损矿山构建了人工表土层,引入了人工种子库,创造了加速植物群落演替的环境.研究结果表明:近 10 年,生态修复区域内的植物群落实现了由草本到灌木,再到乔木的更新,植被评价等级为Ⅱ级;生态修复区域的土壤条件远优于非修复区,土壤评价等级为Ⅰ级.生态修复效果综合评价等级为Ⅰ级,达到了优等水平.团粒喷播生态修复技术能够通过人工干预手段快速构建演替中前期的植物群落,实现群落演替进程的加速.
Abstract
Ecological restoration projects in mines play a vital role in rehabilitating damaged ecosystems and safeguarding the mine′s ecological environment.This paper focuses on the ecological restoration of Beijing′s Shouyun mine,constructs an artificial topsoil layer in the damaged mine through the agglomerate spraying ecological restoration technology,and introduces an artificial seed bank to facilitate the accelerated succession of plant communities.The findings demonstrate a noteworthy improvement in the plant community over a decade,transitioning from herbs to shrubs and eventually to trees,resulting in a vegetation evaluation grade of Ⅱ.Moreover,the soil condition in the ecological restoration area surpassed that of the non-restoration area,earning a soil evaluation grade of Ⅰ.Overall,the comprehensive evaluation grade of the ecological restoration effect attained a superior level of grade Ⅰ.The agglomerate spraying ecological restoration technology was instrumental in rapidly establishing the plant community during the pre-successional stage and effectively accelerating the community succession process through artificial intervention.
