| 摘 要： | 目的]研究丛藓科植物重金属含量对环境的指示作用。方法]选取Cu、Zn、Cd、Pb等主要重金属元素为营养富集指标,对河北省邢台太行山区丛藓科藓类植物体内及其土壤中的重金属含量进行了分析。结果]丛藓科植物小反纽藓、花状湿地藓和丛本藓对Pb、Cu、Cd、Zn有较强的吸收能力,植物体内重金属元素含量较高,对环境污染具有指示和富集作用。不同丛藓科植物对重金属的积累能力有显著差异,其中花状湿地藓对重金属具有较强的富集能力。结论]丛藓科植物可作为环境指示生物进一步研究。

| Abstract: | Objective] The aim was to study the indicative function of heavy metal contents in pottiaceae on environment.Method] Taking important heavy metal elements Cu,Zn,Cd,Pb,etc.as nutrition accumulation index,heavy metal contents in pottiaceae and their soil collected from Taihang mountain area in Xingtai of Heibei Province were studied.Result] Timmiella diminuta(C.Muell.) P.C.Chen,Hyophila rosea Williams and Anoectangium aestivum(Hedw.) Mitt.had stronger absorptive capacity to Pb,Cu,Cd and Zn.There were higher heavy metal contents in plants,which had an indicative and accumulation function on environmental pollution.There was significant difference in accumulation abilities of pottiaceae to heavy metals,among them Hyophila rosea Williams had a stronger accumulation ability to heavy metals.Conclusion] Pottiaceae could be taken as the biological indicator of environment for further study. |
