| 摘 要： | 通过调查有螺滩地林下植被的演变和乌柏（Ｓａｐｉｕｍｓｅｂｉｐｅｒｕｍ）、枫杨（Ｐｔｅｒｏｃａｒｙａｓｔｅｎｏｐｔｅｒａ）等滩地造林树种的灭螺效果发现，鸡矢藤（Ｐａｅｄｅｒｉａｓｃａｎｄｅｎｓ）、水芹（Ｏｅｎａｎｔｈｅｊａｖａｎｉｃａ）的个体数量与钉螺的数量呈正相关关系，Ｘ２分别为１２．８和１１．２（ａ＜０．０２），而益母草（Ｌｅｏｎｕｒｕｓａｒｔｅｍｉｓｉａ）、问荆（Ｅｑｕｉｓｅｔｕｍａｒｖｅｎｓｅ）、酸模叶蓼（Ｒｕｍｅｘａｃｅｔｏｓａ）、打碗花（Ｃａｌｙｓｔｅｇｉａｈｅｄｅｒａｃｅａ）、紫云英（Ａｓｔｒａｇａｌｕｓｓｉｎｉｃｕｓ）等与钉螺的数量呈负相关关系（ａ＜０．０２）经过一个汛期，枫杨、乌柏叶片使钉螺死亡率从草滩对照的２％升至４３．３％和４４．１％

| Abstract: | The dynamics of grasses in herb layer on beaches with snails and inhibition effects of Sapium sebiferum and Pterocarya stenoptera on snails were studied. Individual quantity of Paederia scandens(X2 = 12. 8 ) and Oenanthe javanica (X2 = 11. 2) are positively, and that of Leonurus artemisia, Equisetum arvense, Rumex acetosa, Calystegia hederacea and Astragalus sinicus are negatively correlated with the density of snails(a < 0. 02 ). After the flooding period,the mortality of snails on beaches treated with leaves of Pterocarya stenoptera and Sapium sebiferum is increased by 43. 3 % and 44. 1 %, respectively. |
