中文摘要：

人类活动所引起的温室效应及由此造成的全球气候变化和对全球生态环境的影响正引起人们越来越多的重视。作为全球陆地生态系统一个重要组分，中国的森林生态系统对未来全球气候变化的响应更是人们关注的重点。作者系统地总结了全球气候变化对中国森林生态系统分布、生态系统生产力、森林树种以及森林土壤的影响，指出了现阶段该领域研究中存在的一些问题，并对今后需要加强的一些核心问题与研究重点作了展望。

英文摘要：

More and more attentions have been paid to the human-induced greenhouse effects and their impacts on global climate and eco-environment changes. The global climate changes affect the forest ecosystems, which inversely give a feedback to the global climate changes in a certain extent. As an important part of the global terrestrial ecosystem, the responses and feedbacks of the forest ecosystem in China to the future global climate changes have become very attractive issues. This paper summarizes systemically the impacts of the global climate change on forest distribution, forest productivity, forest species composition and forest soil , and also points out the main problems in the present researches, such as taking into account the extreme climate events rarely, ignoring the interaction between different forest species, considering not enough about the mutual effects and feedbacks between the global climate changes and the forest ecosystem in China, understanding superficially the mechanism on the responses of the forest succession to the global climate changes, and employing the immature model and insufficient data. This paper has applied systemic and exhaustive analyses on the present researches and problems of the impacts of the global climate changes on the forest ecosystem in China, and given some reasonable proposals. In the end, the core issues and key contents about future researches on the forest ecosystems are advanced.
