引发克山病和大骨节病的地理环境因素分析

Analysising Geography Environmental Factors about Keshan Disease and Kashin-Beck Disease

克山病、大骨节病是一种地方性疾病,其分布范围较广,发病率较高.在我国发病区主要位于东北到西南的一条低硒带内,包括黑、吉、辽、内蒙古、冀、豫、晋、陕、甘、宁、川、滇、藏等十几个省区.本文从地理学的角度出发,对我国克山病、大骨节病发病区的地质、地貌、土壤、气候和水文五个地理环境因素进行了分析,分别阐述了各个地理因子的特征与该地区发病情况的关系.指出人们所处的地理环境影响到摄入人体内的化学元素成分,从而导致地方病的发作,因而环境改良工程是解决地方病的重要途径.

Keshan Disease and Kashin-Beck are a kind of regional disease,which has highly incidence of a disease.They exist widely in our country including :Hei, Jil, Liao, Neimenggu, Ji,Yu, Jin, Shan, Gan, Ning,Chuan, Dian,Zang and so on. From geography angle, the article analyses geography environmental factors, which cause the Keshan Disease and Kashin-Beck Disease,such as geologic, landscape, soil, climate and hydrology, and elaborate separately relationship between the feature of different geography factors and the area of disease.In the end,the article concludes that the geography environment affects chemical elements in people′s body, and we should take measures to improve our living condition.
