【摘要】 采用线路调查与标准样地调查相结合、定性与定量分析相结合的研究方法,对阜新海州露天矿排土场30年的天然植被和8年的人工植被进行演替规律分析.结果表明:不同样地的植物组成及分布存在较大不同.在天然植被演替进程中,蒺藜是先锋草种,而披碱草、芦苇、水稗草是重要的优势草种;人工刺槐林和白榆林下的狗尾草重要值最大;人工覆土模式的虎尾草重要值最大.以植被演替流程图为参考依据,适时选择对应排矸年限的优势物种建立植被群落,能明显加快矿区植被演替进程.更多还原

【Abstract】 In this study,the succession rules for 30 years’ natural vegetations and 8 years’ artificial vegetation at the dump of Haizhou opencast mine in Fuxin were investigated using the methods of route survey and standard sample land investigation,and the method combining qualitative analysis with quantitative analysis.The results show larger differences of plant composition and distribution in different sample lands.In the natural vegetation succession process,tribulus terrester is a pioneer grass while the important advantage grasses include elymusdahuricus turcs,phragmites australis and echinochloacrusgalli.The robinia pseudoacacia and setaria viridis under an artificial plantation mode are most important.The chloris virgata is most important in an artificial cover soil improvement mode.Based on the vegetation succession flow diagram,the succession of ecological system in mine can be obviously speeded up by choosing dominant species in a right time according to the dumping years to build vegetation community.更多还原
