本文探讨了微量元素钼在吉林省原生环境各要素中(包括土壤、粮食、饮水)的分布规律。发现从吉林省西部向东部天然水中和粮食中铝含量逐渐减少,土壤中全钼和有效铝含量低于正常值,土壤水溶性钼含量东部山地低于西部台地平原。从生物地球化学角度,编制了钼的分区图,将吉林省原生环境中钼的分布划分为两个“钼区”和五个“钼亚区”。
In this paper, the distribution of molybdenum in various elements of the native environment of Jilin Province (including soil, grain and drinking water) was discussed. It was found that the content of aluminum in natural water and grain decreased from the west of Jilin Province to the eastern part of China. The content of total molybdenum and available aluminum in the soil was lower than the normal value. The content of soil water-soluble molybdenum in the eastern mountainous region was lower than that of western Taiwan terraces. From the perspective of biogeochemistry, the zoning map of molybdenum was compiled, and the distribution of molybdenum in the native environment of Jilin Province was divided into two regions of molybdenum and five molybdenum sub-regions.
