| 摘 要： | 以复垦20a的平朔露天煤矿排土场生态系统为研究对象,从土壤重构到先锋树种筛选及生态系统恢复不同阶段植被演变、动物定居、微生物、土壤养分变化等方面,系统分析了其生态重建技术的实施效果。结果表明,平朔矿区已形成＂黄土母质直接覆盖表层培肥熟化＂特色复垦技术;筛选出刺槐×油松×柠条,刺槐×油松,刺槐×沙棘,刺槐纯林等多种植被配置模式;随着复垦年限的延长,野生物种大量入侵,土壤种子库逐渐形成,物种多样性增加,植被群落组成趋于稳定,动物、微生物和土壤养分呈现增加趋势,表明矿区生态系统已进入正常的演替过程。但受矿区特殊生境和自然客观条件的限制,演替过程中某些植被出现病虫害、种内或种间的水分竞争等问题已导致部分植被退化,因此植被恢复成功后其生态管理还需进一步研究。 |

| Abstract: | Taking a reclaimed ecosystem in dump of Pingshuo opencast coal mine for 20 years as the research object,the implementation effects of ecological rehabilitation technologies were analyzed including soil reconstruction,screening pioneer species,vegetation succession and changes of animal,microorganism and soil nutrient.Results showed that the particular reclamation technologies-dump surface were covered directly by loess parental material,then ripened by fertilizing,were developed in Pingshuo mine.Many vegeta... |
| Keywords: | opencast coal mine soil reconstruction vegetation succession animal microorganism soil nutrient |
