本文应用多元线性回归方法,分析了滩地野粪污染程度及家畜活动频度对感染性钉螺分布的影响,并观察了滩地综合治理措施控制血吸虫病的效果.结果表明,阳性螺密度及钉螺感染率与滩地畜粪污染程度及家畜活动频度之间存在回归关系,通过滩地综合治理,滩地阳性螺密度、钉螺感染率及附近居民血吸虫感染率均得到明显控制,并取得了良好的经济效益.
In this paper, multivariate linear regression method was used to analyze the impact of the degree of wild stool pollution and the frequency of livestock activity on the distribution of snails infecting snails, and to observe the effect of integrated treatment measures to control schistosomiasis.The results showed that positive snail density and snail infection rate There was a regression relationship between the degree of animal dung pollution and the frequency of livestock activity in the beach. Through the comprehensive management of the beach land, the positive density of the beach and snails, the infection rate of snails and the infection rate of nearby residents were all significantly controlled, and achieved good economic benefits.
