采用双向指示种分析法(TWINSPAN)和除趋势对应分析(DCA)对新疆喀纳斯旅游区森林群落进行了数量分类和排序。结果表明:①采用TWINSPAN等级分类方法,将森林群落划分为9个类型;②TWINSPAN和DCA相结合应用能较好地反映出各森林群落之间以及森林群落与环境之间的关系;③DCA排序第一轴从左到右,湿度在逐渐增大,第二轴从下到上,气温逐渐降低,沿对角线方向,海拔逐渐升高。影响喀纳斯旅游区森林群落类型和植物种分布格局的主要环境因子是海拔梯度、水分和热量。
Two-way indicator species analysis (TWINSPAN) and the trend-out analysis (DCA) were used to classify and sort the forest communities in Kanas tourism area in Xinjiang. The results showed that: (1) TWINSPAN classification method was used to divide the forest communities into 9 types; (2) The combination of TWINSPAN and DCA could reflect the relationship between forest communities and forest communities and environment; (3) The axis from left to right, the humidity gradually increased, the second axis from the bottom up, the temperature gradually decreased, along the diagonal direction, the elevation gradually increased. The main environmental factors influencing the types of forest communities and the distribution pattern of plant species in Kanas tourism area are the altitude gradient, water and heat.
