摘　　要：在川西北高原大骨节病区致病因素研究与水文地球化学调查工作中,对大骨节病高发区壤塘县的不同水源类型进行取样并进行中子活化测试。分析结果表明,微量元素在该区域呈富集特征,大体上呈现量高病重、量低病轻的规律,特别是Se元素与其他大骨节病区相比较也呈富集特征,但重病区低于轻病区,符合KBD研究的一般规律。不同水源类型比较,微量元素总量大小排列为溪沟水>土井水>深井水>沼泽水>泉水。In the study of the factors responsible for Kaschin-Beck disease in northwest Sichuan plateau and the hydorgeochemical conditions of this area, the authors conducted neutron activation tests on the samples collected from different types of water sources in the Kaschin-Beck disease area. The results show that the enrichment of trace elements is obvious in this area, and that high element content is coincident with higher illness whereas low element content is consistent with lower illness. Relative to things of other Kaschin-Beck disease areas, selenium in this area is especially abundant; nevertheless, low selenium content is in accord with higher illness, which conforms to the KBD general laws. A comparative study of different types of sources reveals that the content of total trace elements decreases in order of brook waterwell waterdeep well watermarsh waterspring water.
