中文摘要 豚草(Ambrosia artemisiifolia)是原产于北美的恶性入侵植物,目前在辽宁省已广泛分布,主要分布于河流湿地周边,对原生植被造成了严重影响。本文采用样地调查法对河流湿地的豚草进行了调查分析。结果显示豚草优势群落和本土植物优势群落呈镶嵌分布格局;豚草的入侵对本土植被的植物物种多样性是有明显的不利影响,生物多样性指数平均下降34.3%;豚草对物种均匀度的影响相对较小;在人为干扰较重的区域豚草与原生先锋植物竞争中更有优势。

英文标题 Investigation on Effect of Ambrosia artemisiifolia on native vegetation in Liaoning's river Wetlands

英文摘要 Ambrosia artemisiifoliais an invasive plant originated in North America.and has been widely distributed in Liaoning surrounding the river wetland,it has a serious impact on the native vegetation.This article used sample plot method to investigated Ambrosia artemisiifolia surround the river wetland.Results show that dominant community of Ambrosia artemisiifolia with dominant community of native vegetation is mosaic distribution forms;the invasion has decreased the biodiversity of native vegetation,the average biological diversity index decreased by 34.3%;it has less influence in species evenness;Ambrosia artemisiifolia have more advantage in competition with native pioneer plants.

英文关键词 Ambrosia artemisiifolia;river wetland;vegetation;biodiversity
