绿色勘查在土地质量地球化学调查中的探索与实践

Exploration and Practice of Green Exploration in Geochemical Survey of Land Quality

土地质量调查作为地球化学勘查的一种技术手段,具有覆盖面积广、样品类型多等特点。在传统土地质量调查基础上开展绿色勘查具有重要的意义。依据土地质量地球化学调查方法技术体系,提出了土地质量地球化学绿色勘查工作思路,依托胶东典型丘陵区“山东省莱阳北部地区土地质量地球化学调查与评价”项目,系统总结了土地质量地球化学调查中生态环境敏感区识别、点位布设及优化、样品采集及回填、样品加工、采样工具优化等方面的绿色勘查经验和做法,开展了绿色勘查示范,为推广绿色勘查在地球化学勘查工作方面提供了借鉴依据。

As a technical means of geochemical exploration,land quality survey has the characteristics of wide coverage and many types of samples.It is of great significance to carry out green exploration on the basis of traditional land quality investigation.According to technical system of land quality geochemical survey methods,the idea of green land quality geochemical exploration has been proposed.Relying on the project of"land quality geochemical investigation and evaluation in the northern area of Laiyang,Shandong Province"in the typical hilly area of Jiaodong area.The experience and practice of green exploration in the identification of eco-environmental sensitive areas,the layout and optimization of points,the collection and backfilling of samples,the processing of samples,and the optimization of sampling tools in land quality geochemical investigation have been systematically summarized.Green exploration demonstration has been carried out.It will provide some references for the promotion of green exploration in geochemical exploration.
