摘要
利用土壤微量元素资料1972944个数据,地形地貌资料4502个数据,岩石类型资料1092个数据,气象要素资料6361080个数据,癌死亡调查资料5537例。研究了食管癌死亡率与人群所生存的地质环境(土壤微量元素、地形地貌、岩石类型)和气象环境(年平均气温、年平均温差、年平均相对湿度)的相关性。在此基础上。
This paper presents the studies on the relativities between the death rate of the cancer of the esophagus and geological environment (trace elements of soil、topographical geomorphic、the types of rock), meteorological environment (atmospheric temperature of mean annual、temperature differential of mean annual、relative humidity of mean annual) in the living areas of people group by means of the information of trace elements of soil with 1972944 data、topographical geomorphic with 4502 data、the types of rock with 1092 data、the essential factors of meteorological phenomena with 6361080 data and the investigations of 5537 examples about the death of the cancer. On the basis of the study it makes the comprehensive appraissal on the influence of geological and meteorological environment with related to the cancer of the esophagus as to the occurring and developing of the cancer of the esophagus.
