| 摘 要： | 以9个指标反映若尔盖高原湿地生境的环境特征，在ArcGIS 9.2平台下进行随机样方布设，采用DCCA排序方法定量分析湿地景观与环境要素之间的关系。结果表明：(1)排序前2轴累计解释了湿地景观与环境要素关系的79.4％，表明其具有有效的目标研究显示度；(2)沿地形指数所近似表达的水分状况梯度，研究区各景观类型具有明显的...

| Abstract: | Nine indices,such as elevation,topographical index,precipitation,temperature,soil,etc,were used to define the environmental characteristics of wetland habitats in Zoige Plateau.Based on ArcGIS 9.2 platform,scatter quadrats were randomly generated,sample-environmental factors matrix and sample-landscape structure matrix were obtained through spatial analysis module.And then,a DCCA was used to quantitatively analyze the roles of the environmental factors and their effects on the spatial distribution of wetlan... |
