中文摘要	基于宁夏已知甲虫物种分布信息,结合相关气候与生境数据,采用广义可加模型和方差分解方法探讨了甲虫物种多样性分布格局及其与环境因子的关系。结果表明, 宁夏甲虫物种丰富度及科属区系分化强度呈现南、北部高,中部低,西部略高于东部的变化趋势。聚类分析表明,宁夏甲虫地理分布可分为六盘山山地甲虫地理群、黄土高原甲虫地理群、荒漠绿洲甲虫地理群和贺兰山-罗山山地甲虫地理群。GAM分析表明,最冷季平均温度、最湿月平均降雨量和植物物种丰富度分别是影响甲虫物种分布最显著的因子。方差分解结果显示,水分、能量与生境异质性三者共同解释了物种丰富度82.4%的变异;能量与水分因子共同解释了甲虫物种丰富度 79.6%的空间变异,单独解释率分别为19.9%和14.0%;生境异质性解释了甲虫物种丰富度26.3%的变异,单独解释率仅为2.8%。宁夏地区甲虫物种丰富度空间分布格局由能量和水分因子共同决定,生境异质性有助于提高甲虫物种丰富度。
英文摘要	Based on the distribution information of beetles and the data of climate and habitat in Ningxia,we explored the relationship between the distribution patterns of beetle species diversity and environmental factors. The results showed that species richness and fauna differentiation intensity of beetles were higher in southern and northern areas than in central area,and higher in western area than in eastern area. Results of clustering analysis showed that the geographic distribution of beetles in Ningxia could be classified into four groups (Liupan Mountain beetle group, loess plateau beetle group,desert oasis beetle group,and Helan-Luoshan Mountain beetle group). Results of GAM analysis showed that mean temperature in the coldest season,mean precipitation of wettest month,and plant species richness were the dominant factors affecting beetle distribution. Variance decomposition results showed that water,energy and habitat heterogeneity together explained 82.4% of the total variations of beetle species richness. Energy and water factors together explained 79.6% of the spatial variation in beetle species richness,with independent explanations of 19.9% and 14.0%,respectively. Habitat heterogeneity explained 26.3% of the spatial variation,with only 2.8% independently. Our results indicate that beetle species richness patterns are predominantly shaped by energy and water factors together,and that habitat heterogeneity helps enhance beetle species richness in Ningxia.
