中文摘要	潜在植被作为陆地生态系统的重要组成部分,能够真实反映立地气候环境,对其分布特征的研究可为生态工程评价提供依据。本文以综合顺序分类系统理论为基础,选取 RegCM3模型及A2情景下的预测数据,模拟了20712100年中国潜在植被的空间分布。结果表明,21世纪中国潜在植被均发生了不同程度、不同方向的变化,具体表现为:温带森林和冻原高山草地向冷干方向变化,其中温带森林为中国主体潜在植被;亚热带森林向较冷地区演替;温带荒漠、热带森林及热带稀树草原向冷湿方向迁移;半荒漠向暖湿地区集中分布;干草原、温带湿润草地及热带荒漠向暖干方向变化,其中温带湿润草地和热带荒漠的空间分布重心迁移显著。本文揭示了21世纪中国潜在植被的变化规律,可为我国21世纪生态建设战略提供参考。
英文摘要	Potential vegetation, as an important part of the terrestrial ecosystem, could accurately reflect the local climate, and studying the distribution characters of potential vegetation would provide relevant references for the evaluation of ecological engineering. In this paper, the forecast data computed by RegCM3 model under scenario A2, was selected based on the Comprehensive Sequential Classification System (CSCS) to simulate the spatial distribution of potential vegetation in China from 2071 to 2100. The results indicated that all potential vegetation regions in China would change at different levels and directions. The temperate forest, which is the dominating part of Chinese potential vegetation, would change to colder and drier direction, so would tundra and alpine steppe. Frigid desert, tropical forest, and savanna all showed a moving trend to colder and wetter direction, the semi-desert vegetation mainly distributed in warm-humid regions, while steppe, temperate humid grassland, and warm desert showed a moving trend to warm-dry direction. Significant movement of spatial distribution center would occur for temperate humid grass-land and warm desert. These results revealed the changes of potential vegetation in China for the 21st century, which can provide potential references for future national ecological construction strategy in the 21st century.
