珠穆朗玛峰地区处于亚热带低纬度的海拔四千米以上的高原面上。由于巨大的山体的屏障作用,形成了迎向暖湿气流的山地南侧发育着海洋性的自然带谱。山地北侧分布着大陆性的自然带谱,相应产生了复杂的土壤垂直带谱,为研究土壤地球化学提供了良好的条件。同时,珠穆朗玛峰地区人类活动稀少,是全球环境背景值研究的典型区。本文将探讨本区镉、铅的土壤地球化学特征和提供镉、铅的土壤背景值。
Everest region in the subtropical low-latitude elevation of 4,000 meters above the plateau. Owing to the barrier function of the huge mountain, a natural oceanographic band is developed on the southern side of the mountain facing the warm-humid airstream. The northern part of the mountain distributes the continental natural band spectrum, and the corresponding complex vertical soil band spectrum is produced, which provides a good condition for the study of soil geochemistry. In the meantime, there are few human activities in Everest region, which is a typical area of global environmental background value research. This article will explore the cadmium and lead in this area of soil geochemical characteristics and provide cadmium and lead soil background values.
