金沙江干热河谷植被恢复研究进展

Research Progress on Vegetation Restoration in the Dry-hot Valleys of the Jinsha River

植被恢复是金沙江干热河谷区生态恢复的有效途径。分析了金沙江干热河谷特殊的自然条件和恶劣的生态环境现状,回顾了金沙江干热河谷自1950年代以来的植被恢复历程,综述了金沙江干热河谷植被恢复中的理论研究、品种选择、技术突破、效益评价等的研究进展,指出了目前本区植被恢复中研究手段、方法和内容等方面的不足,强调今后研究应注重加强高新技术的应用,重视植被恢复的科学性、现实性和可操作性,及加大乡土种的筛选与应用研究等方面的内容。

Vegetation restoration is an effective approach of ecosystem restoration in the dry-hot valleys of the Jinsha River. The special natural conditions and the degraded ecological environment in the dry-hot valleys of the Jinsha River were analyzed, the history of vegetation restoration since 1950＇s was reviewed. The theories research, the species choose, the technological break-through and the benefit evaluation in vegetation restoration in the dry-hot valleys of the Jinsha River were summarized, and the shortage of the means, method and contents in the research was point out. At last it puts forward suggestion such as paying more attention to the application of high and new technique, attaching importance to science, practical and exercisabilitv in vegetation restoration,and strengthening the research of the local species.
