长江三峡建坝对江汉平原血吸虫病传播的影响——农业生产结构与血吸虫病的关系

THE IMPACT OF THREE GORGE DAM (TGD) CONSTRUCTION ON THE SCHISTOSOMIASIS TRANSMISSION IN JIANGHAN PLAIN——THE RELATIONSHIP BETWEEN AGRICULTURE STRUCTURE AND SCHISTOSOMIASIS TRANSMISSION

为探讨三峡建坝对江汉平原血吸虫病传播的影响,采用历史回顾的方法,在湖沼垸内水网型血吸虫病流行区潜江市收集1985—1994年10年间工、农业生产结构及血吸虫病流行情况的资料。结果表明,当地水田面积与钉螺面积、水田面积与人群感染率、钉螺面积与人群感染率之间均呈正相关关系。牲畜血吸虫感染率与人群感染率之间亦有密切相关。

A typical lake region with serious schistosomiasis endemic areas was selected as the study field. In the study,the 10 years (1985 - 1994) data about the agriculture sturcture and schistosomiasis prevalence was collected and analyzed. The results showed significant posi-tive correlationships among the infection rate,the total area of snail habitat and paddy field. The infection rate of human had a close relation to the infection rate of domestic animals.
