青藏高原植被变化对区域气候影响研究进展

Advances of the Study on Influence of Vegetation Change over Tibetan Plateau on Regional Climate

陆地生态系统与气候变化之间存在这密不可分的相互作用过程。青藏高原地区是全球气候变化的敏感区,全球变暖对高原陆地生态系统演变的影响非常明显,这必将导致高原生态系统变化。生态系统的变化又将会引起局地、区域气候的响应,导致局地、区域、甚至全球的气候变化。因此研究青藏高原地区植被演变及其与气候变化的关系是一个有着重要学术价值和实际意义的课题。本文在对青藏高原植被与气候关系研究回顾的基础上,介绍了近年来关于青藏高原植被变化对区域气候影响取得的新的进展,提出了一些可能的物理过程,同时指出了研究中存在问题及今后的工作重点。

This article was based on the research review of relationship between vegetation in Qinghai -Xizang Plateau and climate, which has introduced the latest development of the influence that the vegetation in Qinghai - Xizang Plateau had on the regional climate. In recent years, it has been a great development that the influence of the land surface progress of Qinghai - Xizang Plateau had on the regional climate, and its related researeh achievement＇ s influence on the understanding the background of global warming and the evolution of vegetation in Qinghai - Xizang Plateau, which with potential influence on the regional climate in China and significant meaning of its mechanism ; and its former stage of change＇ s influence on the climate of latter stage, which could be applied in the short term climate forecasting will have a great prospect. However, the land surface process still has a great number of problems to be studied, since the scarce of Qinghai - Xizang Plateau meteorological and ecological materials, it could be lucubrated the following fields of the land surface progress： 1. take the full advantage of diversified measures and add more possibility to apply the limited materials; 2. lucubrate the land - atmosphere reciprocity in the cold and drought regions, and improve the model parameterized program; 3. consummate the dynamic vegetation - atmosphere reciprocity model, which could achieve the two - way coupling of climate model. 4. take the further step to study the Qinghai - Xizang Plateau bioclimatology.
