Abstract: On seasonal beaches, the density of survival oncomelania is positively correlated with flood duration, and the latter is negatively correlated with tree growth performance.When the flood duration is increased by a day, the density of survival oncomelania will be increased by 2269 individuals per hectare.Construction of snail-outwipping agroforestry ecosystem on grass beaches could reduce 84% of the survival oncomelania density after three years.
