摘要
20世纪50年代末到21世纪初,对青海高原沙漠化的分布、基本特征、沙丘类型、形成演化、风沙移动规律、野外观测、沙化监测的科学考察研究到防沙治沙试验的过程;从地域上涉及了青海的柴达木盆地、共和盆地、青海湖盆地、黄河源区和长江源区全部5个沙漠化土地分布地区,全面综述了高原沙漠化研究的成果、防沙治沙经验和研究进展,提出了存在的问题及今后研究的内容。
At present, the source region in Qinghai of the three big rivers of China, with the most seriously ecological environment of desertification, is the most important one in ecological environment construction of our country. Therefore, researches on the sandy desertification in this region are of great significance. In present years, a lot of achievements on desertification and its control have been got. This paper reviewed the research progress on desertification of Qinghai plateau from the end of 1950s to the early 21 century, including scientific surveying, desert distribution, basic desertification characteristics, sand dune types and their formation and evolvement, law of blown sand movement, filed observation and desertification monitoring, and experiment of sand prevention and control, etc. Researches related to the five desertified land distributing areas： Qaidam basin, Gonghe basin, Qinghai lake basin, source region of Huanghe river and source region of Changjiang river. Accordingly, the problems existed in the above research fields and the contents need further study were put forward in the paper.
