| 基于生境属性和典型调查法，开展了定南稀土矿区苔藓植物分布的特征与下覆土壤理化性质的相关性研究。结果表明，定南稀土矿区有苔藓植物9科15属15种。其中苔藓植物物种多样性最高的生境为稀土尾矿堆场区长有五节芒植物群落的地块。苔藓植物的优势科有4科，为曲尾藓科（Dicranaceae）、金发藓科（Polytrichaceae）、丛藓科（Pottiaceae）、葫芦藓科（Funariaceae），占总科数的40.0%，含有9属10种，占定南稀土矿区苔藓植物总属数的60.0%，占总种数的 66.7%。苔藓植物的优势属为拟金发藓属，包含2种，占总种数的百分比为 13.3%。相似性指数最大为路边五节芒样地和沟渠石壁样地。对苔藓植物群落盖度与土壤理化性质的相关性分析表明，土壤有机质、全氮、全磷含量对苔藓植物的分布都有显著影响。研究结果可为掌握赣南稀土矿区苔藓分布特征、苔藓结皮改良土壤等方面提供基础数据支撑。 |

| The correlation between the distribution characteristics of bryophytes and the physical and chemical properties of the underlying soil in the rare earth mining area in southern Jiangxi Province was studied based on the habitat attributes and the typical investigation method. The results showed that there were 15 species, 15 genera and 10 families of bryophytes in Dingnan rare earth mining area. The habitat with the highest bryophyte species diversity was the plot of rare earth tailings yard with argyria plant community. There were 4 dominant families of bryophytes in the Dingnan-rare-earth mining area, which were Dicranaceae, Polytrichaceae, Pottiaceae and Funariaceae, accounting for 40.0% of the total number of families, including 9 genera and 10 species, accounting for 60.0% of the total number of genera and 66.7% of the total number of species of bryophytes. The dominant genus of bryophytes is Polytrichastrum G. Sm, including 2 species, which accounts for 13.3% of the total species number. The similarity index was the largest in the roadside and ditch rock - walled plots. Correlation analysis of bryophyte community coverage with soil physicochemical properties showed that soil organic matter, total nitrogen and total phosphorus contents had significant effects on the distribution of bryophytes. The research results of this paper can provide basic data support for understanding the distribution characteristics of moss and soil improvement of moss crust in the rare earth mining area in southern Jiangxi Province. |
