| 摘 要： | 根据对四川王朗自然保护区地震干扰后恢复群落的野外调查数据,运用二元指示种分析(TWINSPAN)和除趋势对应分析(DCA)对该地区恢复群落进行了数量分类与排序。结果显示,可将所调查的植物群落划分为3种群落类型:重度干扰群落(群落E)、中度干扰群落(群落T)和轻度干扰群落(群落F)。排序结果也得到了相同的结论,并显示3种群落分布与一定的环境因子密切相关,群落E与岩石裸露度呈正相关,而与土壤厚度、土壤水分、苔藓盖度及盖度等环境因子呈负相关,群落F则与岩石裸露度呈负相关,而与土壤厚度、土壤水分、苔藓盖度及盖度等环境因子呈正相关。 |

| Abstract: | The plots were classified into three communities by the methods of TWINSPAN and DCA,they are the community recovered from intensive earthquake disturbance(Community E),intermediate earthquake disturbance(Community T),and slightly disturbed forest community(Community F).The first axis of DCA indicated clearly the tendency from intensive to slight disturbance caused by earthquake.The results of ordination by DCA also showed the close relationship between plant communities and environmental factors.The community E was positively related to the coverage of exposed rock surface,and negatively related to the moss cover,while the community F was negatively related to the coverage of exposed rock surface,and positively related to the moss cover. |
