摘要: 研究表明,草滩钉螺密度与淹水时间呈正相关,淹水时间与林木生长性能呈负相关。淹水期每增加1天,钉螺密度上升2269个·hm-2.滩地实施抑螺林业生态工程3年后钉螺密度下降84%.

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.
