[Effect of sand buried on elimination of Oncomelania hupensis snails in marshland along Yangtze River in Jiangdu District, Jiangsu Province].

OBJECTIVE

To evaluate the effect of sand buried on the elimination of Oncomelania snails in the marshland along the Yangtze River downstream.

METHODS

The areas along the Yangtze River were chosen as the investigated objects in Jiangdu District, Jiangsu Province. The datum review and field investigations were used to observe the change of snail area after the sand buried.

RESULTS

There were 11 sand buried projects along the Yangtze River in Jiangdu District, Jiangsu Province. The snail areas decreased by 93.73% after the sand buried.

CONCLUSION

The sand buried is an effective method of snail control in the marshland along the Yangtze River. This method can be combined with economic construction and development projects for popularization and application.
