The result of dca ordination shows that diffirent plant communities and their distributing area vary with the environmental grads in the ordination graph when the first axis of dca denotes altitude change and the sencond axis of dca denotes change of water equivalent in the soil Dca排序结果表明, dca第一轴反映海拔变化, dca第二轴表示土壤含水量的变化,随着环境梯度变化,不同的植物群落在排序图上也有各自的分布范围。
