青海省防治沙漠化区划研究

按照区划的原则和依据,将青海省沙漠化土地划分为4区10个亚区。柴达木盆地荒漠区划分为冷湖风蚀区、格尔木流沙区、都兰流沙区、德令哈戈壁区和乌兰固沙区5个亚区;共和盆地半荒漠区划分为共和流沙区和贵南流沙区2个亚区,青海湖盆地环湖区只划分1个亚区;青南高寒区划分为可可西里风蚀区和黄河上游阶地风蚀风积区2个亚区。针对各亚区沙漠化土地现状和特点,提出了合理开发方向和防治途径。

REGIONALIZATION OF DESERTIFICATION CONTROL IN QINGHAI PROVINCE

The desertified lands in Qinghai Province are divided into 4 regions and 10 sub regions based on the principle and basis of regionalization:(1) The desert region of Qaidam basin includes 5 sub regions of Lenghu wind erosional region, Golmud sand shifting region, Dulan sand shifting region, Delingha Gobi region and Wulan sand fixed region; (2) The semi desert region of Gonghe basin consists of Gonghe and Guinan sand shifting sub regions; (3) The Qinghai Lake arounding area is only divided into one sub region; (4) The alpine cold region in south Qinghai has two sub regions which are wind erosional regions both in Kekexili and in the upper Yellow river reaches terrace area. Against the status and characters of desertified lands in each sub region, the rational developing directions and controlling approaches have been suggested.
