传统的水利血防工程采用硬质护岸形式，极大程度地影响了河道生物多样性。依托某水利血防工程，在对河道附近水位站潮位资料统计排频的基础上，给出了常规硬质护岸的设计方案。结合植物抑螺理念，设计出一种生态型的抑螺护岸。并将不同抑螺植物组合设置成三个生态抑螺护岸试验段。通过现场调查比较，硬质护岸和生态抑螺护岸都能起到灭螺效果，相对于硬质护岸河流景观单一化，生态抑螺护岸更贴近自然，三个生态护岸实验区中，以密毛酸模叶蓼为挺水植物，以益母草为草本植物的试验段植物存活率更高。

Rigid revetment is widely used in traditional water conservancy and anti-schistosomiasis projects. It has a negative impact on the biological diversity of watercourses. A regular rigid revetment was designed for a water conservancy project based on the tidal data of a nearby gauging station. A new type of snail controlling revetment was also designed according to the idea of snail controlling by plants. Moreover, three experimental sections were created with different combinations of snail controlling plants. The site survey showed that both rigid revetment and ecological revetment were effective in controlling oncomelania. But the ecological revetment is more natural compared with the rigid one. Among the three test sections, the section with densely hairy sorrel smart weeds as emerged plants and leonurus as herbaceous plants had the highest plant survival rate.
