摘要
[目的]分析采石场废弃地的植被自然恢复过程,为人工辅助其生态恢复提供依据.[方法]在对河北省井陉县不同恢复年限采石场废弃地进行植物调查的基础上,对其群落特征、物种组成及物种多样性进行了分析.[结果]自然演替2a采石平台和自然演替2a道路边坡的植物群落结构相似,物种组成较简单,以1年生草本为主,且物种多样性低;自然演替11a采石平台和自然演替13 a道路边坡物种多样性较演替2a标准地有较大提高,物种以多年生草本和灌木为主.[结论]自然演替13 a道路边坡植被明显好于自然演替11a采石平台植被,通过改善采石废弃地的立地条件,遵循植被的演替规律,可以加快其植被演替进程.
Abstract
[Objective] To analyze the natural vegetation restoration process of abandoned quarries,and to provide important references for the restoration by artificial supplementation.[Method] Based on the plant sample investigation of abandoned quarries with different natural recovery period in Jingxing County of Hebei Province,we analyzed the community characteristics,species composition and species diversity.[Result] Pant community structures of quarries platform and road slopes were similar after two years with simple species composition and low species diversity.Among them,annual herb was the dominant.The species diversity of eleven years' natural community succession on the quarries platform and thirteen years' natural community succession on the road slop had considerable improvement,compared with two years' natural community succession.Among them,perennial herb and shrub were the dominant.[Conclusion] Plant of thirteen years' natural community succession on the road slop is superior to the plant of eleven years' natural community succession on the quarries platform.Improving the site conditions and following the vegetation succession rule can greatly accelerate the vegetation succession process.
