摘　　要： 地球化学元素是万物生长的基础物质,它与诸多动植物的生存、生长密切相关。尽管地球属于一个统一的整体,但各种地质作用的复杂性导致地表元素的分配产生了差异,这些差异表现为区域性的地球化学元素异常。大量研究表明,地球化学异常对人类活动和区域性生态构成产生重要的影响,前者表现为区域性地方病,后者表现为区域性植物种类的差异以及同类型植物的生长异常。因此,区域性地球化学的研究既有助于地方病的研究,又可以对农业区划进行指导。本文在前人研究的基础上,针对国内外地球化学异常研究现状、地球化学元素迁移及地球化学异常对农业和常见地方病的影响这三方面进行综合评述,旨在探究应用地球化学在农业及医疗保健中的意义。 Geochemistry chemical element is the fundamental substance of all things on earth which is closely related to the zoology and botany survival and growth.Although the earth belongs to a unified whole,each geological process＇s complexity caused the different assignment of the surface element whose performance was unusual for the regional geochemistry element.The massive research indicated that the geochemical anomaly had the important influence to the human activity and the regional ecology constitution,the former presented regional endemic,and the latter manifested the difference of the regional plant species and the same type of plant.Therefore,the research of regional geochemistry is not only conductive to the study of endemic,but also can guide agricultural regionalization.Based on the foundation of the predecessor studies,this article makes a comment about the domestic and foreign geochemical anomaly research present situation,the geochemistry element migration and the effects of geochemical anomaly on agriculture and common endemic.The purpose of this study is to explore the significance of application geochemistry on agriculture and health care.
