摘要
为研究沉螺池阻螺效果,2007 ～2010年在长江中下游5省疫区引水洲滩设置了10处沉螺池螺情变化跟踪监测点.通过5 a的螺情跟踪监测和研究,在国内首先提出典型水利血防工程——沉螺池防螺效果定量评价指标及评价方法,并取得了有意义成果.评价结果认为,沉螺池对阻止钉螺扩散有一定效果,但要取得更大成果,还必须配合沉螺池下游灭螺、沟渠硬化、沉螺池清淤等措施.
In order to research snail control effect of snail settling pool, 10 tracking and monitoring points arranged at several water diversion beaches for epidemic surveillance were established in the epidemic areas of 5 provinces in the middle and lower stream of Changjiang River from 2007 to 2010. After 5 years monitoring and research, the quantitative evaluation indexes and e- valuation methodology for snail settling pool are put forward and some active achievements are obtained. The snail control effects of 10 snail settling pools are evaluated by the presented evaluation index system. The evaluation results show that snail settling pool has some effect to snail diffusion controlling, but for gaining better effects, the measures of snail eradication in downstream of snail settling pool, canal hardening, dredging of snail settling pool etc should be adopted at the same time.
