北川片口驴蹄草(Caltha palustris)群落特征研究

The Community Characteristics of Caltha palustris in Piankou of Beichuan County

  • 摘要: 为合理保护和利用片口自然保护区内疑似新种的驴蹄草,本文采用样方法调查和分析了片口自然保护区内片口驴蹄草的分布区域和群落特征。研究结果显示:片口驴蹄草集中分布在海拔在2 000 m~2 300 m之间的山谷溪边或湿草甸,对土壤要求不高,对湿度要求较高。片口驴蹄草群落的植物种类隶属9科11属,以毛茛科和荨麻科植物为最多。片口驴蹄草是群落的优势种,且在群落中呈聚集分布类型。

     

    Abstract: To rationally protect and utilize the suspected new species Caltha palustris in Piankou nature reserve,investigation and analysis were made of the distribution and community characteristics of Caltha palustris by using the sampling method. The results showed that the community was mainly distributed in valley streams or wet meadows with the altitude of 2 000 m~2 300 m. The request of Caltha palustris was not high for the soil fertility, but was higher for the humidity. The plant species of the Caltha palustris community belonged to 11 genera and 9 families, which were dominated by Ranunculaceae and Urticaceae. The Caltha palustris was a dominant species in the community, and its importance value was 115, far larger than that of Cardamine macrophylla, whose importance value was 47 and was the second largest one in the community.
