北山戈壁荒漠地区1∶5万植物地球化学测量效果

THE EFFECT OF 1∶50000 GEOCHEMICAL VEGETATION SURVEY IN THE BEISHAN GOBI DESERT REGION

北山戈壁荒漠景观区土壤垂直剖面不存在通常的A、B、C分层结构,且掺杂有大量风成沙。在公婆泉地区开展1∶5万常规地球化学测量方法研究的同时,进行了植物地球化学测量试验研究。研究表明,两种方法的主要指示元素异常有很好对应性,红沙是我国西部干旱荒漠广大地区开展植物地球化学测量的一种良好采样对象。

In the region of Beishan Gobi desert, there is usually no existence of A, B, and C layering construction in the vertical section of soil and a large quantity of breeze sands are mixed. At the same time, both 1:50000 routine geochemical survey and geochemical vegetation survey are carried out in the Gongpoquan district. The research results show that there is good correspondence for the main indicator elements of these two kinds of methods. Reaumur iasoongorica is a good sampling object for the geochemical vegetation survey in the vast arid desert areas of western China.
