[Effect of land consolidation project on detention of Oncomelania hupensis snails in flood at Yangtze River beach].
OBJECTIVE
To explore the effect of land consolidation project on the detention of Oncomelania hupensis snails in the flood at the Yangtze River beach.


METHODS
The land consolidation project including removing wild willow groves, cutting the high and filling the low, and improving the slope was carried out at the Yangtze River beach in 2011, and the status of snails was investigated before and after the project, respectively, at the end of the flood season.


RESULTS
Before the project (2010), at the end of the flood season, the rate of the frames with snails was 96.5% and the snail density was 3.655/0.1 m2. After the project (2012), at the end of the flood season in the same area, the rate of the frames with snails was 2.0% and the snail density was 0.015/0.1 m2 (chi2 = 357.29, P < 0.01).


CONCLUSIONS
The land consolidation has a significant effect on the detention of snails in the flood at the Yangtze River beach.
