覆盖区多目标地球化学调查数据应用前景浅析--以江苏省国土生态地球化学调查有关成果为例

多目标地球化学调查是一项基础性、公益性地质调查工作，江苏省的多目标地球化学调查是全国实施此项工程的重要组成部分，可作为覆盖区开展此项工作的一个代表。本文简介了江苏省开展多目标地球化学调查工作的基本情况，用具体实例说明了多目标地球化学调查数据在示踪人类活动对自然土壤环境的影响、研究区域地质背景对土壤环境的制约作用、开展局部土壤生态环境安全预警、指导开发利用局部富Se土壤资源等方面的初步应用效果，对江苏省多目标地球化学调查资料的应用前景及如何进一步利用好多目标地球化学调查数据的相关问题进行了专门探讨，并提出了有关建议。

Prospects of applications of multi-target geochemical survey data in covered areas-Example from relevant results of ecological geo-chemical survey of land in Jiangsu, China

Multi-target geochemical survey is a fundamental,commonweal geological survey,and the multi-target geochemical survey in Jiangsu Province is an important component part of this nationwide project and may serve as a representative of this work carried out in covered areas. This paper briefly introduces the basic aspects of the multi-target geochemical survey in Jiangsu,and describes with examples the effects of applications of the multi-target geochemical survey data in tracing the influence of human activities on the natural soil environment,studying constraints of the regional geological setting on the soil environment,giving early-warning of the safety of the soil ecological environment in local areas and guiding the exploitation and utilization of local Se-rich soil resources. At last,the paper discusses problems of applications of the multi-target geochemical survey data in Jiangsu Province and how to further use the multi-target geochemical survey data and puts forward some relevant suggestions.
