摘　　要：通过野外调查和文献查阅的方法,研究了河南连康山与小秦岭自然保护区种子植物组成及科、属区系成分,揭示了地理条件对植物区系形成及成分差异的影响;应用Czehanowski相似系数,分析了2个区域科、属植物区系成分及相似性特征。结果表明:连康山有种子植物143科716属1 808种(含变种),分别占河南全省种子植物科、属、种总数的94.08%、79.91%、61.22%;小秦岭有种子植物134科705属2 004种(含变种),分别占河南全省种子植物科、属、种总数的88.16%、78.68%、67.86%。连康山与小秦岭植物区系在科、属两级水平上均以热带、亚热带成分为主,以泛热带分布占绝对优势,而温带分布属同时占据相当大的比例,呈现出南北交汇、暖热过渡的共同特征。2个区域科、属和种的相似性系数分别为92.8%、81.07%、61.80%,适应不同纬度的地理条件变化和局部生境异质性的长期演变,同一科属植物群体在种的层次上出现了深层次的分化,造就了2个区域丰富的植物资源。Based on field investigating and reference collection,the seed plant composition and the flora of families and genera in Liankang Mountain and Xiaoqinling Nature Reserve were studied,the influence of geographical conditions on flora formation and composition were revealed,and the difference and similarity characteristics of both families and genus flora were analyzed with the Czehanowski formula.Results showed that there are 1808 species of seed plants,belonging to 143 families and 716 genera(including various species)in Liankang Mountain,accounting for 94.08%,79.91%and 61.22%of total families,genera and species in Henan Province respectively;and there were 2004 species of seed plants,belonging to 134 families and 705 genera(including various species)in Xiaoqinling,accounting for 88.16%,78.68%and 67.86%of that in Henan,respectively.At the level of family and genus,Liankang Mountain and Xiaoqinling flora are mainly tropical and subtropical,and the pan-tropical distribution is dominant, while the temperate distribution occupies a considerable proportion at the same time, showing the common characteristics of the intersection of north and south, and the warm and thermal transition. The similarity coefficient of family, genus and species was 92.8%, 81.07% and 61.80% respectively, for adaptation to changing geographical conditions at different latitudes and local habitat heterogeneity, plant groups of the same families and genera appeared widely differentiation at the species level, and which creating the rich plant species resources in both Liankang Mountain and Xiaoqinling.
