湖北省是我国南部亚热带向北部暖温带过渡地带,又是我国东部丘陵向西部高原过渡地带。因而植物区系显示出南北交汇、东西渗透的丰富复杂的特点。加之第四纪冰川的侵蚀,对湖北地区影响甚微,使大量古老孑遗植物得以保存,因此,湖北早已成为世界瞩目的植物种质资源天然基因库。全省种子植物172科,3858种(含变种),其中木本植物有122科,1680余种,约占全省种子植物科数的71%,种数的42%,在全球同纬度地区中,木本植物在种子植物中所占的比例,以湖北最大,这一特点,反映了湖北植物区系的多样性、复杂性和古老性。
Hubei Province is the transition zone of the warm subtropical zone to the north in the southern part of our country and the transitional zone from the hilly area to the western plateau in eastern China. The flora thus shows a rich and complex trait of north-south intersections and east-west infiltration. Combined with the erosion of the Quaternary glaciers, little impact on the Hubei region, so that a large number of ancient relict plants to be preserved, therefore, Hubei has long been the world’s attention plant genetic resources, a natural gene pool. The province’s seed plants 172 families, 3858 species (including varieties), of which 122 families and woody plants, more than 1680 species, accounting for about 71% of the province’s seed plants, 42% of the species in the global latitudes The proportion of woody plants in seed plants, the largest in Hubei Province, reflects the diversity, complexity and ancientness of Hubei flora.
