| 摘 要： | 中国新疆地区表土花粉研究结果展示了干旱区主要孢粉的空间分布规律,大部分表土花粉属种的地理空间分布与含量与相应植物的分布区域基本一致,藜科、蒿属、麻黄属及木本植物云杉属、桦木属等花粉普遍呈超代表性,柽柳属花粉呈低代表性。干旱区主要草灌木表土花粉数据的聚类分析结果可以基本反映本区植物群落的主要生态组合类型。主成分分析进一步表明该区草本和灌木花粉分布主要受水文和湿度等因素控制。 |
| 关 键 词： | 表土孢粉分布 旱生植物 聚类分析 主成分分析 新疆地区 |

| Abstract: | The present study analyzes the pollen distribution in Xinjiang Region.The results show clearly that pollen percentage localities are accordant with their dominant community of vegetation.Artemisia pollen has relative high percentage on the Kunlun Mountains,the Altay Mountains and around Junggar Basin.Chenopodiaceae pollen occur widely on the Altay Mountains,Junggar Basin,the Tianshan Mountains and the Kunlun Mountains.Ephedra and other shrub pollen occur highly around Tarim Basin.The distribution of tree pollen,such as Picea,Betula ,is mainly on the Altay Mountains and the Tianshan Mountains.The results of cluster analysis can reflect the main ecology assembalges of plant communities in study area.The result of principal component analysis confirms that the distribution of steppe and shrub pollen are mainly controlled by hydrology and humidity factors in study area. |
| Keywords: | Modern pollen distribution xeromorphic vegetation Cluster Analysis Principal Component Analysis Xinjiang Region |
