区域化探资料在人居环境评价中的应用

研究认为,区域化探每个样品实际控制面积绝大多数都小于1 km2,可认为与土壤样品元素含量在同一水平,二者元素含量的变化不影响区域人居地球化学环境的评价,水系沉积物样品因其综合性,更能反映研究区污染的全貌。运用区域化探资料开展区域人居环境评价具有普适性。在此基础上,以云南个旧地区为例,首次运用区域化探资料对该区域人居环境进行了初步评价。

Utilization of Regional Geochemical Data in Living Environment Evaluation

Living environment refers to a kind of local or district environment,which is different from regional or global environment and residence.Regional living geochemical environment refers to regional rich or lack elements and corresponding transforms(including pathological changes) of mankind and living geochemical environment.It is stated that it is generally suitable for regional geochemical data to be utilized to evaluate living geochemical environment standard,it is also generally suitable to select one or more elements which had been proved to have conspicuous effects on organism by medical geology,agricultural geology and environmental geology on the base of classifying elements,to reflect the overall living environment of an area.Taking Gejiu area as an example,this paper utilizes regional geochemical data to evaluate regional geochemical environment for the first time.
