则曲河流域水化学特征与大骨节病的关系研究

大骨节病是一种严重影响则曲河流域居民身体健康和经济发展的地方病。通过对壤塘县则曲河流域不同区段大骨节病的调查，结合相应的水化学环境及水质检测结果，分析了各区段的水化学特征及不同区段、不同水化学环境的基本状况，开展了大骨节病与水化学特征之间关系的综合研究。研究发现该流域大骨节病发生与饮用水的溶解性总固体和总硬度偏低，腐殖酸偏高等因素有关，其成果可为病区大骨节病防治提供相应的依据。

A study of the relationship between hydrochemistry and kaschin-beck disease in the Zequ river basin

Kaschin-beck disease is an endemic disease which has a serious effect on the human health and economic development.This article analyses the basic situation of different regions and different hydrochemical environment and develops a comprehensive research between the Kaschikn-beck disease and hydrochemical characteristics through investigating the kaschin-beck disease of different regions in the Zequ river of Rangtang county.The hydrochemical environment is combined with the analysis results of water quality,and the hydrochemical characteristics in each section are also examined.The research results show that the occurrence of the kaschin-beck disease in the river is related with low salinity and total hardness and high humic acid.The results can provide relative basis for controlling the kaschin-beck disease in the endemic area.
