摘　　要：对山东省珍稀濒危植物的研究发现,共有65科、123属和159种珍稀濒危植物,其中蕨类植物5科5属6种,裸子植物8科17属26种,被子植物52科101属127种。珍稀濒危植物在山东省各地市的分布极其不均,丰富度较高的多为山地丘陵地区,如青岛市、烟台市和泰安市,这些地区保护的珍稀濒危植物均在100种以上;同时发现山东省25个省级以上自然保护区保护了珍稀濒危植物的95.59%。对自然保护区和地市这2个空间尺度下的珍稀濒危植物分布影响因素研究发现,在这2个空间尺度下均受到温度和海拔因素的显著影响,并且在地区尺度下受海拔的影响要明显大于自然保护区尺度,表明在生物多样性的保护工作中应该认真对待栖息地的异质性。Statistics and analysis of rare and endangered plants in Shandong Province found that there are 65 families,123 genera,and 159 species of rare and endangered species in Shandong Province.Among them,5 families,5 genera,and 6 pecies belong to pteridophytes;8 families 17 genera 26 species belong to gymnosperms;52 families,101 genera,and 127 species belong to angiosperms.The distribution of rare and endangered plant is extremely uneven.Rare and endangered plants are also abundant in areas with more mountains and hills,such as Qingdao,Yantai and Taian,where more than 100 species of rare and endangered plants are protected.The study also found that 95.59%of rare and endangered plants are protected in 25 nature reserves above the provincial level.Temperature and altitude were the main determinant factors of species richness of rare and endangered plant in the two scales(nature reserve and region).Altitude has stronger effects on rare and endangered plant under the regions scale than the nature reserve scale.The results indicate that habitat heterogeneity should be taken seriously in biodiversity conservation.
