摘　　要：大骨节病是一种地方性变形性骨关节病,阿坝州壤塘县是中国罕见的大骨节病重病区。壤塘县主要饮用水源及饮水水质的调查分析表明,饮水中低矿化度、高腐殖酸是大骨节病患病的重要环境因素,低矿化度导致软骨组织必须的营养元素缺乏,高腐殖酸造成软骨细胞损伤退化。鉴于此,在壤塘县开展了改水工程示范,探索出适合大骨节病区的地下水小型集中供水工程,以达到改善饮水水质,阻断饮水性致病源的目的。Kaschin-Beck disease is a kind of endemic osteoarthritis disease, and Zamgtang County is one of the serious areas of Kaschin -Beck disease. An investigation and analysis of water source and water quality of Zamgtang County have led the authors to believe that the low degree of mineralization and high humic acid in drinking water are two key environmental pathogenic factors for Kaschin-Beck disease in that area. Low degree of mineralization results in the lack of nutrient elements necessary for cartilage tissue, and high humic acid damages cartilage cell. In view of this, water improvement demonstration projects exploiting the small-scale deep groundwater have been put into practice. These projects are suitable for the Kaschin-Beck disease area and will cut off pathogenic factors.
