摘要: 植物系统发育多样性研究服务于区域植被历史、演化规律、生物多样性保护,盐生植物作为区域植被演化的独特类群和未来农业种质资源开发的重要物质基础,其区域系统发育多样性对于揭示区域环境变化、盐生植物种质资源保护、区域开发具有重要意义,但目前为止,这方面的研究匮乏。本文应用植物系统发育多样性理论和方法,以省级行政区为单位,系统评价中国盐生植物系统发育多样性和差异性,构建65科484种,17变种,8亚种盐生植物系统发育树;净谱系亲缘关系指数大于0的只有新疆维吾尔自治区、宁夏回族自治区、甘肃省、青海省、陕西省、内蒙古自治区和北京市;系统发育多样性与科、属、种级物种丰富度相关性依次为67.01%、91.20%和96.99%;根据盐生植物分类学组成相似性和系统发育组成相似性把中国盐生植物分为4大区域。本文结果对于省级行政区域盐生植物资源评估、盐生植物种质资源收集和中国盐生植物分区具有重要的指导意义。

Abstract: Phylogenetic diversity serves regional vegetation history, evolutionary law and the protection of biodiversity. Halophytes are the unique group of regional vegetation evolution and the important material basis for the development of future agricultural germplasm resources. The phylogenetic diversity of halophytes is great significance to reveal regional environmental changes, protection of germplasm resources and regional development,but so far, there is a lack of research in this area. Based on the theory and method of phylogenetic diversity and taking provincial administrative regions as units, we systematically evaluated the phylogenetic diversity and dissimilarity in China. A phylogenetic tree of 484 species, 17 varieties and 8 subspecies of Halophytes in 65 families has been constructed. Only Xinjiang, Ningxia, Gansu and Qinghai,Shaanxi, Inner Mongolia and Beijing have a net relatedness index (NRI) greater than 0. The correlation of phylogenetic diversity with family, genus and species richness was 67.01%, 91.20% and 96.99%, respectively. According to the taxonomic floristicsimilarity and phylogeneticsimilarity of halophytes, Chinese halophytes were divided into four regions. Our results have important guiding significance for provincial halophyte resource assessment, halophyte germplasm collection and halophyte regionalization in China.
