The Qaidam basin is situated in the north-east Qinghai-Xizang plate-au, its distribution pattern of vegetation is very camplicated. The east-ern part of it belongs to the semiarid desert steppe zone with the zonalvegetation desert steppe. The middle part belongs to the arid desert zonewith shrubby and dwalf semi-shrubby gravelly desert. The western part isan extremely arid bare-desert without vegetation in the gravelly gobi andlow mountains. At the bottom of the basin, a ring-shaped belts of the ve-getation from the edge toward the centre shows the following sequence:flood plain-the shrubby and dwarf semi-shrubby gravelly desert belt, all-uvial plain-the shrubby and semi-arboreou sandy desert belt, alluviallacu-strive plain-the shrubby saline desert belt, lacustrine plain-the holophyticgrass and forb meadow belt, and finally, bare salt crust and salt lakes. In the mountains of the Qaidam region there is great difference in thevertical belt spectrum of the vegetation between east and west: the verti-cal spectrum in the desert steppe zone is: mountainous steppe-mountaino-us evergreen needleaf forest-subalpine shrubland-alpine meadow-alpine spa-rse vegetation; in the arid desert zone: dwarf semi-shrub mountain rockydesert-alpine steppe-alpine meadow-alpine sparse vegetation; and in thebare desert zone: bare low mountain rocky desert-dwarf shrubby mountainrocky desert-alpine steppe-alpin sparse vegetation.

柴达木盆地位于青藏高原东北部,其植被分布规律较复杂。东部为半干旱荒漠草原地带,地带性植被为荒漠化草原;中部为干旱荒漠地带,地带性植被为灌木和矮半灌木砾漠;西部为极端干旱裸露荒漠地带,在砾石戈壁和低山基本上无植被。本区盆地底部随着地貌、土壤和地下水的变化,出现了植被环带状分布规律。从盆地边缘向中心依次发育着洪积平原灌木、矮半灌木砾漠带,冲积平原灌木沙漠带,冲积-湖积平原灌木盐漠带,湖积平原盐生草甸带,最后为裸露盐壳和盐湖。本区山地的植被垂直带自东而西明显不同。荒漠草原地带的带谱为:山地草原-山地常绿针叶林-亚高山灌丛-高寒草甸-高山稀疏植被;荒漠地带为:矮半灌木山地石漠-高寒草原-高寒草甸-高山稀疏植被;极端荒漠地带为:裸露低山石漠-矮半灌木山地石漠-高寒草原-高山稀疏植被。

Qaidam is a plateau basin, with an elevation of 2600—3200 m, under climate arid. All the run off of about 440—500 million m~3 yearly is converged into the river-sealed basin owing to reversed drainage, therefor, salt-water balance of the region mainly depends on evaporation. The deposition of salts in this basin have been started at least since Tertiary. In the salts deposited, besides large amounts of halite, carnatite and gypsum, those of B, Li, and Sr had also been enriched. The regularities for the distribution of the saline soils are as follows: Around the big lacustrine basins, the chemical deposition has occurred from the basin centre going outside in the order of chemical sediments→salt mud→salt crust→boggy solonchaks→meadow solonchaks→residual solonchaks→grevelly relic solonchaks with gypsic pan; while around the small lecustrine basins, its order is chemical sediments→salt mud→boggy solonchaks or salinized boggy solonchaks influenced by ground water and surface stagnate water→lacustrine medow solonchaks→grevelly salinized soils or grevelly relic solonchaks with a gypsic salt pan. The width of the salim soil zone depends on the region where they developed. In general near high mountains the distributive zone of saline soils are wide because of many materials carried by running water, while near the low mountains, it is narrow and fawer types of saline soils are distributed in the unsymmetrical form around some basins. Based on the geological history, the geochemical characteristics, this region may be roughly divided into three subregion. Ⅰ.Western sulphate subregion, predominated by CaSO_4, Na_2SO_4, SrSO_4, etc.. Ⅱ.Northern samll basin borate subregion, predominated by NaCl, B, etc.. Ⅲ.Middle and southern part subregion predominated by NaCl, MgCl_2, KCl.

青海柴达木盆地是我国的高原盆地,海拔在2600—3200米,气候干旱,地形封闭,年迳流总量约44—50亿立方米,完全汇集于盆地,主要平衡消耗于蒸发。盆地盐类化学沉积至少自第三纪开始,除沉积大量石盐、光卤石外,硼、锂、锶等元素亦大量富集。盐渍土的类型和分布总的规律是:1.在大湖盆的周围;从湖心起向外推,依次出现化学沉积→盐泥→盐壳→沼泽盐土→草甸盐土→残余盐土→砾质戈壁石膏盐盘残余盐土。2.在小湖盆的周围,从湖心起向外推,依次为化学沉积→盐泥→地下水溢出的部位发育为沼泽盐土或盐化沼泽土→湖滨草甸盐土→砾质盐化土或砾质戈壁石膏盐盘残余盐土。各类型的盐渍土分布带有宽有窄,一般在近高山区一侧,由于水流所携带的物质丰富,分布带宽,规律性亦明显,而在靠低山区一侧窄。按照盆地地质历史特点和盐类地球化学累积特征,划分为三个积盐区:1.西部硫酸盐类累积区,主要以CaSO_4、Na_2SO_4和SrSO_4等盐类;2.北部小盆地以硼酸盐类和氯化物盐类等累积区;3.中、南部为氯化物盐类累积区,主要以NaCl、MgCl_2和KCl等盐类。文章最后提出盆地土地资源的合理开发利用的方向性意见。
