摘要
废弃地是一类极度退化的生态系统。对三峡地区的矿山废弃地、退(弃)耕地、工程建设废弃地、垃圾填埋场、地质灾害废弃地、砍伐迹地等废弃地类型的形成原因进行了调查分析,并结合国内外恢复生态学的研究进展,讨论了该地区废弃地植被恢复与重建的一般规律,对该地区废弃地植被恢复与重建的对策及其方法与步骤提出了一些建议。认为人类干扰是该地区废弃地形成的主要原因。废弃地植被的恢复与重建应该遵循规划系统性、设计与施工生态性、目标植被的物种多样性等原则。而土壤基质的固定与恢复、先锋群落的构建、后期管理中生物多样性的逐步丰富是三峡地区废弃地植被生态恢复与重建过程中三个关键的步骤与内容。
The ecosystems in Three Gorges Area are very frangile with complex and diverse terrain. Many kinds of extremely degraded ecosystems (wasteland) occurred for the long-term disturbance from human and nature. The wasteland type, cause of its formation and the vegetation recover pattern were reported in this paper, then some suggestions were put forward for revegetating the waselands in this area based on the local geographic and ecological condition and the development in restoration ecology. The stabilization and restoration of soil and substrate, the construction of pioneer community and the biodiversity enrichment in management were regarded as the key approaches of wasteland vegetation restoration in Three Gorges Area.
