中文摘要	新疆地处中国干旱区,地形气候复杂,生境类型丰富多样,为研究极端条件下物种丰富度的分布格局及其成因提供了理想场所.利用新疆维管束植物丰富度数据和对应的气候数据,分析水热因子对新疆维管束植物物种丰富度的影响.结果表明:物种丰富度随年降水量和年实际蒸散量的增加单调递增,随年平均气温和年最大可能蒸散量的增加呈单峰型变化.在盆地和山地,物种丰富度随年降水的增加而显著增加;随着年平均气温的增加,物种丰富度在山地呈现出先增加后减小的单峰格局,在盆地中则仅呈现单调下降的趋势.在不同的水分亏缺水平,物种丰富度与年降水量的关系不一致,随着水分亏缺的增大,物种丰富度随年降水增加的速率减小;随着年平均气温的增加,物种丰富度在较低的水分亏缺时单调递增,在较高的水分亏缺时单调递减
英文摘要	Distribution patterns of biodiversity at large scale and their affecting factors are one of the focal issues of ecology. Xinjiang is located in an extremely arid area in northwest China, where there are ideal places to explore the distribution patterns of species richness and their affecting factors under extreme conditions because of the complicated topographical and climatic conditions and the diversity of habitats. In this study, the relationships between the distribution patterns of species richness of vascular plants and the climatic factors in Xinjiang are analyzed based on the available data of vascular plants and climatic factors. The results reveal that the species richness increases with the increase of annual precipitation (AP) and actual evapotranspiration (AET), and the curve of species richness of vascular plants with the increase of MAT and PET is unimodal. In all the subregions, species richness increases significantly with AP. Species richness patterns with the increase of MAT are different in the mountains and basins,it increases at first and then decreases with the increase of MAT in mountains, but decreases monotonically in the basins. At different water deficit (WD) levels, the increase rate of species richness is decreased with the increase of AP at high WD. Species richness increases with the increase of MAT at low WD level but decreases at high WD level
