摘 要：
以四川雅砻江官地水电站人工开挖边坡植被恢复区为研究对象,运用普通生态学研究方法,从群落组成、物种重要值、群落生长型结构及物种多样性等方面,对扰动区4个典型样地进行植被恢复初期的群落特征分析。结果表明:经过1 a的恢复重建,样地内物种总数迅速增加、本地物种大量侵入、物种多样性大幅提高,群落处于演替的初始阶段;同时,初始配置的部分植物如白三叶、爬山虎和油麻藤等过早退出群落,在生境改善和景观价值上未能达到预期效果,建议摈弃或在种植方式上进行相应的改进。

摘 要：
This article used the vegetation restoration zone of artificial slope in Guandi Hydropower Station,Sichuan Yalong River as the research object,from the community composition,the important value,structure of growth and species diversity etc.,it applied the general ecology research methods to analyze the characteristics of community which was located on four typical sample plots of disturbance area.The results showed that,after a year of recovering and reconstructing,the amount of species had increased rapidly in the study areas,the local species had invaded massively,the diversity of species had been improved greatly and the community was in the initial stage of succession;Furthermore,Trifolium repens,Japanese creeper and Caulis mucunae as the initial arrangement plant had basically exited the community too fast,which didn't lead to achieve the desired results in the improving habitat and landscape value.That indicated these three plants should be discarded and proposed for corresponding improvement measures on planting methods.
