摘要:

基于中国知网(CNKI)和学术Google主题词为“气候变化”与“森林”的科技文献,根据全国范围的不同区域植被类型,运用整合分析方法就气候变化对森林生态系统的影响进行了系统评估,结果表明:在观测到的影响中,各个区域植被类型的树木物候、森林生产力与森林火灾方面的影响趋势大体相同,但森林地理分布影响趋势存在一定的差异;在预计的可能影响中,各个区域植被类型的树木物候、森林生产力、森林碳储量、森林火灾方面的影响趋势大体相同,但森林地理分布、森林结构方面的影响存在一定的差异。最后对现有研究的不足及未来研究方向等进行了讨论和展望。

Abstract: Based on the literatures with the subject headings “Climate Change” and “Forest” collected from the CNKI and Google, and according to the regional vegetation types within China, the meta-analysis method was used in this paper to assess the effects of climate change on China forest ecosystems. Among the observed effects of climate change, those on the tree phenology, forest productivity, and forest fire of the regional vegetation types were similar, but definite differences were observed in the effects on the forest geographic distribution. As for the projected effects of climate change, those on the tree phenology, forest productivity, forest carbon storage, and forest fire of the regional vegetation types were similar, but there were some differences in the effects on the forest geographic distribution and forest structure. The main problems of the existing studies and the directions of future researches were also discussed.
