江河源区沙漠化研究进展与展望

在全球气候变暖的影响下,青藏高原作为气候变化的敏感区,受到人们越来越多的重视。江河源区是我国长江和黄河以及国际河流澜沧江的发源地,同时它又是高原的重要组成部分。近几十年来,沙漠化现象在该地区的快速发展蔓延已经引起社会和学术界的广泛关注。本文从沙漠化的发展态势、沙漠化的驱动因子、沙漠化的治理措施等方面的研究现状出发,对江河源区的沙漠化研究状况进行了综述,并对研究中存在的不足和未来的研究重点进行了分析。

Progresses and Perspective of Studies on Sandy Desertification in the Source Regions of Yangtse River,Yellow River and Lantsang River

As a sensitive area to climate change,Qinghai-Xizang plateau attracts more and more attention on the background of global warming.Source regions of Yangtse River,Yellow River and Lantsang River is an important part of Qinghai-Xizang plateau.Sandy desertification occured there and spread very rapidly.This article summarized the sandy desertification researches on Source regions of Yangtse River,Yellow River and Lantsang River based on the distribution of desertification land,driving factors of desertification and engineering measure of desertification,hoping to be helpful for future study of this region.
