Evaluation on the effect of composite detachable oncomelania blocking net for preventing oncomelania at the water intake of the electric irrigation station
【摘要】 目的 评价复合可拆卸式拦螺网防螺效果。方法 对有螺河道的电灌站进水口改建进水池,加装复合可拆卸式拦螺网。通过投螺试验以及对有螺河道和试验电灌站灌区渠系螺情监测,评价拦螺网防螺效果,并记录现场水文数据和防螺工程费用。结果 复合可拆卸式拦螺网防螺工程拦螺效果达100%,工程费用为51 307.26元。结论 复合可拆卸式拦螺网防螺工程防螺阻螺效果好,适合在苏南水网地区有螺河道电灌站推广。远期防螺效果和效益需进一步观察。
【Abstract】 Objective To evaluate the effect of composite detachable oncomelania blocking net on preventing oncomelania diffusion.Methods The water intake of electric irrigation station was transformed on the river where oncomelania exists, and the composite detachable oncomelania blocking net was installed to prevent the diffusion of oncomelania. The effect of oncomelania prevention projects was evaluated by throwing oncomelanias with different color markings on the near water pump side and far water pump side of the network, as well as monitoring the oncomelania situation in the river and the canal system at the irrigation area of the experimental electric irrigation stations. The hydrological data of the research site and the cost of the project were recorded. Results The effect of the composite detachable oncomelania blocking net for preventing oncomelania was 100%, and the project cost was 51 307.26 yuan. Conclusion The composite detachable oncomelania blocking net project has a good effect of preventing and blocking oncomelania, and is suitable to be popularized among the electric irrigation stations on the river channels with oncomelanias in the water network area of southern Jiangsu. The long-term effect and benefit of oncomelania control need to be further observed.
