| 摘 要： | 应用典范对应分析（CCA）对辽宁东部白石砬子国家级自然保护区56个样地中的森林植被和44种主要树种与8个环境因子间的关系进行了研究。结果表明，海拔高度、样地坡度、土壤有机质、林冠都闭度和土壤酸度是影响白石砬子森林树种和植被分布的主要因素。结合双向指示种分析（TWINSPAN），在CC样地一环境因子双序图上区分出8个样地组，分析了8个样地组的植被成员组成及其分布与环境因子间的关系。 |

| Abstract: | The paper analyzed relationship between distributions of vegetation and major tree species and environment factors.In Baishilazi Nature Reserve,eight environment factors and vegetation and 44 tree species were surveyed in 56 plots.Canonical Correspondence Analysis(CCA) revealed that altitude,slant grade,proportion of soil organic matter,canopy density and soil acidity were main factors influencing distribution of vegetation and major tree species.Based on Two-Indicative-Species-Analysis(TWINSPAN),eight site groups were identified on site-environment variable two dimensions graph,the main components of communities and their relationship with environmental factors were analyzed. |
| Keywords: | Baishilazi state nature reserve CCA tree species vegetation environment |
