苔藓植物对酸性恶劣土壤环境的适应性研究

摘要

苔藓植物结构简单，对土壤环境的变化反应敏感，是良好的生物指示植物。该研究通过室内模拟实验的方法，分析苔藓植物对富含酸的恶劣土壤环境的适应性。结果表明，苔藓植物对酸性恶劣土壤环境的适应性较差，但苔藓植物具有一定改善生存环境基质的能力，因而能作为恶劣土壤环境下的植物物种先锋，以帮助其它物种的安全进入。同时对本地区苔藓植物的多样性保护以及合理利用苔藓植物进行酸性环境污染监测有一定理论和实践价值。%Bryophytes are simple in organic structures and sensitive to changes of soil environment so they can be used as excellent bioindicators.Conducting simulation experiment indoors,this study analyzes the adaptive ability of bryophytes to the soil environment rich in acid.The result shows that bryophytes have poor adaptive ability to undesir⁃able acidic soil environment,but they are capable of improving poor soil environment.Therefore,it is possible to plant bryophytes as the initiatives in undesirable soil for other plants settling in.This study has theoretical and practi⁃cal values in multidimensional protection of local bryophytes and making good use of bryophytes to monitor acidic en⁃vironment pollution.
