陕西省区域环境地球化学分区

为了利用地壳元素分布特征与动植物微量元素含量间的关系,指导生态环境综合治理,借助已有的基础地球化学资料,进行陕西省地球化学分区,确定各分区的环境背景值、污染起始值、缺乏临界值、过剩值临界值,并将陕西省分为陕北、关中、陕南3个地球化学区,圈定了1个元素贫化区和2个元素富集区。提出应该在元素的缺乏和过剩的异常区内进行生物体内微量元素含量的定期检测。做到对地球化学疾病及时发现及时寻找对策,以保证人类生存环境的安全,提高生存质量。

ZONING OF ENVIRONMENTAL GEOCHEMISTRY IN SHAANXI PROVINCE

for the purpose of using the relationship between distribution feature of crust elements and microelement content of flora and fauna, guiding Comprehensive Harnessing of ecological environment, the author take a geochemical zoning with the aid of existed basic geochemical data, to establish the environmental background value, contaminative initial value, critical value of element deficiency, lack and excess in each zoning, devided whole area in Sha'anxi Province into three geochemical zoningsnorthern, middle and southern zoning, and delimited a impoverishment area and a excess area of element content. Finally,put forwarded that should periodically detect the micronutrient content in living body in these anomaly area, and accomplish discovery at the last moment on geochemical disease and look for corresponding countermeasure, to guarantee safety of human living environment and improve one's own living quality.
