It is considered that soil environmental geochemical quality study should be undertaken in two aspects : current soil quality assessment and soil contamination grade assessment , the concept and aim of these two assessments being different from each other 摘要从概念内涵和应用目标出发，认为土壤环境地球化学质量评价应该分为质量现状和污染程度两个方面。
The tasks of ecological - geochemical mapping include rational land use and regional programming , investigation of environmental geochemical baseline related to human health , prognosis of mineral resources and researches on agricultural geochemistry 生态地球化学填图的任务包括4个方面：土地合理利用和区域规划研究、环境地球化学基准调查及其与健康关系研究、矿产资源预测和农业地球化学研究。
Geochemical database can be classified into 6 types , namely , solid ore geochemical database , oil and gas geochemical database , isotope geochemical database , agro - ecological environmental geochemical database , geochemical analytical database and standard reference materials database 地球化学数据库可概括为固体矿产地球化学数据库、油气地球化学数据库、同位素地球化学数据库、农业生态环境地球化学数据库、地球化学分析数据库和标准物质数据库等6大类。
In this paper , the authors studied environmental geochemistry of hohhot , divided soil secondary environments according to their qualities , probed into the soil environmental geochemical element migration , and put forward some opinions for tackling various environmental geochemical problems 摘要介绍了呼和浩特市环境地球化学特徵，对该区土壤次生环境进行了质量分区划分，探讨该区土壤环境地球化学元素迁移概略，提出了土壤环境地球化学治理的具体意见。
Based on the investigation and g1s software of arc view , an environmental geochemistry gis of the shallow groundwater in city zone and close suburb of beijing is developed . the system can do many jobs for the environmental data of groundwater such as collection , storage , management , analysis and calculation , which shows a powerful function in spatial search , analysis , display and programing . in the two years of 2000 and 2001 本文在详细调查北京城近郊区浅层地下水污染情况的基础上，根据需要，对地理信息系统软件arcviewgis3 . 2a进行了二次开发，建立了北京城近郊区浅层地下水环境地球化学gis系统，实现了对地下水环境数据的采集、存储、管理、分析、计算和图形显示等多种功能，展示了强大的空间查询、分析和编程能力。
Advanced apparatus and instruments should be used to strengthen abstraction and identification of environmental geochemistry information , and to reveal the formation mechanism of acid mine drainage under complex conditions , to reveal speciation and transformation of heavy metals in acid mine drainage and their ecological effect , and establish the geochemical model to predict and prevent the formation of acid mine drainage 文章述评了这三种污染源的环境地球化学效应，提出需要进一步加强矿山环境的矿物转化过程中环境地球化学信息的提取和识别，揭示复杂条件下酸性矿山废水中金属的形态、转化过程及其生态效应，建立相应地球化学演化模型，为矿山环境治理提供理论依据。
With the method of taking advantage of both seismic prospecting and seismic logging for locating and anticipating water resources and environment , it offers a reference for decision - making for control of water pollution , protect of water environment and durative development of resources and , also a demonstration of the general use of environmental geophysics and geochemistry , being both advanced academically and practically 联合运用地震勘探和测井技术进行选址和预测评价水资源和水环境，可为污染的治理和水环境的保护以及确保资源的可持续发展提供决策依据，可以说是环境地球物理、环境地球化学理论、方法、技术的具体表现，有很高学术水平和实用价值。
