摘要
2005年7月15日对厦门海沧青礁海堤外的互花米草进行药物杀除,试验选用的除草剂对互花米草的杀除有效.药物喷洒后不同时段调查结果表明:试验区与对照区的底栖生物种类组成、生物量、栖息密度同步对比数量相差不明显,其随时间变化的趋势亦呈现总体一致.这表明互花米草防除药物对底栖生物群落组成结构及其生境的干扰不大,试验区与对照区底栖生物群落组成结构总体一致的变化趋势与时序有关.
We have effectively killed smooth cordgrass （Spartina alteriflora ） outside the Qingjiao dyke of Haicang by using selective herbicide on 15th, July, 2005. After spraying the herbicide, the results with time show that no obvious quantitative difference occurred in benthic species composition, biomass, inhabit density and the coherent variation trend between experimental zone and controlled zone. We concludes that the selected herbicide for smooth cordgrass does not obviously affect community composition and the habitats of benthic species, the coherent variation trend of benthic community composition correlates with time between experimental zone and controlled zone.
