摘要: 风灾区的植被恢复对长白山森林生态系统稳定发展、生物多样性保护具有十分重要的意义,一直是长白山自然保护区内研究的重要问题。本研究在野外调查风灾区目前植被恢复情况的基础上,以空间明晰的方式确定森林生态系统的稳定性,根据不同的稳定性等级采用不同的恢复措施,最后应用森林景观模型评价恢复措施在短期和长期的植被恢复效果。结果表明:人工造林可以有效地改善植被恢复,长期效果尤为明显;因此,控制生态系统中不稳定的因素,降低不稳定因素的扩散能力,使不稳定生态系统、亚不稳定生态系统逐步向稳定生态系统转变,需要以人工造林为主,自然恢复为辅,创造良好的条件,促进一个群落发展成为由当地物种组成的完整生态系统,以实现当地的天然植被覆盖为最终目标。

Abstract: The vegetation restoration in the wind disaster area in Changbai Mountains Nature Reverse plays an important role in the stable development of forest ecosystem and the protection of biodiversity, which has been an important research issue in the Reverse. Based on the field investigation on the current status of vegetation restoration in the wind disaster area, this paper quantified the stability of forest ecosystem by a spatially explicit way, and evaluated the effects of different restoration measures on the vegetation restoration in short and long term by using forest landscape model. The results showed that reforestation could efficiently improve vegetation restoration, especially in long term. Therefore, to control the unstable factors in ecosystem and reduce the spread ability of unstable factors could make the unstable and sub-unstable ecosystems convert to stable ecosystem. For these purposes, it would be needed to reforest with a supplement of natural restoration and to create good conditions for the development of a plant community to a complete ecosystem with local species composition to realize the local  natural vegetation cover as the ultimate goal.
