摘要: 青藏高原土地沙漠化研究具有十分重要的理论与实践意义,近年来国内积极开展了对青藏高原土地沙漠化问题的调查与研究,并取得了一系列成果,本文对该项研究所取得的主要进展及存在问题进行了综述。首先,回顾了青藏高原沙漠化研究的发展历程,其中50年代至70年代为第一阶段,该阶段的研究主要侧重于进行沙漠考察与沙害治理,沙漠化研究还未真正开展起来;80年代为第二阶段,期间青藏高原沙漠化研究已逐步开展起来,尤其是重点对青海共和盆地的沙漠化问题进行了研究与分析;进入90年代为第三阶段,青藏高原沙漠化研究全面展开,研究区域广泛,研究内容系统、全面,研究成果丰硕,是该区沙漠化研究最为重要的时期。其次,总结了青藏高原沙漠化研究的现状与主要进展,包括经过广泛研究,基本上查清了青藏高原土地沙漠化的类型、面积、分布与危害等,填补了沙漠化研究在青藏高原地区的空白;青藏高原沙漠化研究中特别重视了其成果的应用问题,将区域土地沙漠化现状、成因、趋势、防治对策与措施及其规划作为一个有机整体进行系统研究,拓展和完善了沙漠化研究的内容;研究中首次确定了沙砾质、沙漠化土地类型,并提出了沙漠化成因的多因性和地域性,发展了沙漠化研究的基本理论;同时,还加强了沙漠化防治实用技术的研究。最后,分析了研究中存在的主要问题,如研究区域不尽平衡、基础研究较为薄弱、理论研究有待深入和防治技术亟待提高等,提出今后青藏高原沙漠化研究的主攻方向与主要研究项目。

Abstract: Sandy desertification research in Qinghai Xizang plateau has very important theoretical and experimental significance. In recent years, the problem of sandy desertification in Qinghai Xizang plateau has been investigated and studied, and some results were gotten. This paper summarizes the main progresses and problems of research on sandy desertification in Qinghai Xizang plateau. First, the paper reviews the development process of research on sandy desertification in Qinghai Xizang plateau, which can be cut into 3 stages. In first stage, from 1950's to 1970's, the major researches are on desert investigation and sandy hazard control. In second stage, in 1980's, research on sandy desertification in Qinghai Xizang plateau was begun, especialy the problem of sandy desertification in Gonghe basin of Qinghai was deeply studied. In 1990's, the third stage is the most important period of research on sandy desertification in Qinghai Xizang plateau, the sandy desertification problem in almost all over the Qinghai Xizang plateau was studied, its research content is comprehensive and systematic and a lot of research results were gotten. Second, the status and main progresses of sandy desertification research in Qinghai Xizang plateau are summarized: ① Through research on the sandy desertification in Qinghai Xizang plateau, the area and type and distribution as well as damages of desertification have been clearly investigated, this fills in the blanks of research regions of sandy desertification in Qinghai Xizang plateau. ② In the research on sandy desertification in Qinghai Xizang plateau, the status, causes, trend, control strategy and measures and control planning of regional sandy desertification have been taken as a organic whole to be systematically studied, which developed and completed the research content of sandy desertification. ③ In the research on sandy desertification in Qinghai Xizang plateau, gravel desertified land was definited at first time, and the concept of multiple and regional causes of sandy desertification was given, which developed the basic theory of sandy desertification study. ④ At the same time, the study applying techniques to combat sandy desertification has been intensified. At last, this paper also analyses the problems of research on sandy desertification in Qinghai Xizang plateau, for examples, unbalance in research region, lack in study basis and theoretical research and control techniques, etc. And the directions and major items of sandy desertification research in Qinghai Xizang plateau are given.

Key words: Qinghai Xizang plateau, sandy desertification, research progress
