人类和地理环境中某个或某些环境条件如地质、地形气候、水或土,有着依存关系。或者说反映了某些疾病与环境中一系列生态系统间的依存关系。十年前,地球化学家发现.地壳中各种化学元素的丰度(即平均含量)曲线,与人血中相应元素的丰度曲线,有着惊人的相似情况。而且发现:不同的地质环境中的人 There is a dependency on one or some of the environmental conditions in human and geographical environment such as geology, terrain climate, water or soil. Or reflect the dependence of certain diseases on a range of ecosystems in the environment. Ten years ago, geochemists found that the abundance (ie average content) curve of various chemical elements in the crust had a striking resemblance to the abundance curve of the corresponding element in human blood. And found: people in different geological environments
