库姆塔格沙漠地区土壤及分布特征

库姆塔格沙漠是我国最后一个进行大型资源环境综合考察的沙漠。该区域土壤研究被列为国家科技部科技基础工作专项“库姆塔格沙漠综合科学考察”的9个科学考察专题之一。通过2007年和2008年两次秋季野外集中科考，得到的初步结论是:在土壤类型和分布特征方面，库姆塔格沙漠地区地带性土壤类型为棕漠土，土壤分布高度地带性显著，存在多种地带与非地带性土壤类型中微域组合。在土壤形成发育和演变方面，表现出土壤形成过程中的风蚀、沙化严重，常使许多土壤类型处于复幼过程；土壤盐分表聚明显；土壤形成发育和演变过程受水文过程主导；区域土壤普遍肥力低下。

Soil Types and Their Distribution Pattern in the Kumtagh Desert

The Kumtagh Desert is the last desert being broadly scientifically explored in China. The soil research subject was one of the nine subjects in the program of the Integrated Science Exploration in Kumtagh Desert, which was a China National Science & Technique Basic Work Program. The primary research result was described as below through two field explorations at the autumn in the year 2007 and 2008. The zonal soil type is the brow desert soil in the area of Kumtagh Desert. The vertical distribution pattern ...
