摘　　要：在广东内伶仃岛选择薇甘菊危害较严重的3种类型环境“坡地、低洼地、水泽地”设立15个样地,每个为10×10m,各样地分别喷洒不同药量(0.0005～0.3g/m^2)的森草净,经过一年的持续观察,结果表明:0.01～0.1g(有效成分)/m^2的森草净对样地薇甘菊有极好的杀灭效果;森草净对样地的草本植物有一定的影响,对藤本植物基本无影响,除几种含有乳汁的敏感植物外,对木本植物影响较小;森草净施药前后相比较,样地物种多样性恢复较好,整体上施药后物种多样性有明显增加。Three kinds of environment such as "Sloping field, bottomland and swampland" badly covered by Mikania micrantha H.B.K. in Neilingding iSland of Guangdong province was divided into 15 plots with 10 m x 10 m each and were used to be tested the effects of herbicide sulfometuron-methy (concentration 0.0005- 0.5 g/m2) killing Mikania micrantha and its influence on the plant diversity. The observation results lasting one year was showed: (1) when the herbicide concentration is 0.01 -0.1 g/m2, it is with a well killing effect on Mikania micrantha; (2) This herbicide is almost no influence on the vine plants, with faintness influence on the herbaceous plants and lesser influence on the woody plants besides several sensitivity plants contained latex e. g. Boehmeria nivea (L.) Gaud., etc.; and (3) Comparing with before using herbicide and after using herbicide, the species diversity of plots is renew very-well, and in the whole the species diversity is increased obviouSly after using herbicide.
