- The results showed that the contents of heavy metals in soils contaminated around the copper - zinc smeltery were higher than those in non - polluted soils
结果表明，在冶炼厂周边土壤几种重金属含量与对照区土壤相比明显的增加。 - The results show that the soil has been polluted by the municipal waste leachate , the concentration of heavy metal in landfill soil is higher than that in unpolluted soil
结果表明，受垃圾渗滤液的浸蚀影响，垃圾区周围土壤酸性增大，养分含量增高；垃圾区土壤的重金属含量明显高于对照区土壤，表明垃圾区周围土壤已受到渗滤液的重金属污染，土壤性状发生明显变化。 - 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
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。 - 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
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。
