摘　　要：分析丽水市各县(市、区)植物区系特征及开展区系分区,可更深入地掌握该市植物区系性质与特点,为植物资源保护与开发利用提供科学依据。本文通过野外调查(2018—2019年)和资料收集(2017—2019年),对丽水市各县(市、区)植物名录进行了梳理。结果表明,丽水市有野生种子植物160科921属2785种,以庆元县物种数最多,有155科784属2069种,科、属、种数分别占丽水市种子植物科、属、种总数的96.88%、85.12%和74.29%,龙泉市次之。地理成分上,科级层面热带分布科数与温带分布科数的比值为2.00,各县(市、区)热带分布科数与温带分布科数的比值在1.84~2.09之间,表明科级以热带起源为主;属级层面热带分布属数与温带分布属数的比值为0.83,各县(市、区)分布属数与温带分布属数的比值在0.75~0.89之间,表明属级以温带起源略占优势。植物区系分区上,大体以云和、松阳为界,可以分为西部中山区(Ⅰ区)和东部低山区(Ⅱ区)。其中,Ⅰ区可划分为庆元—龙泉亚区、遂昌亚区和景宁亚区3个亚区;Ⅱ区可分为云和—青田—缙云亚区、松阳亚区和莲都亚区3个亚区,各亚区之间相互联系,又各有特色,体现了丽水种子植物区系的复杂性和多样性。龙泉—庆元亚区和景宁亚区物种多样性指数最高,是今后深入挖掘特色物种的重点区域。Based on literatures and field investigations during 2018 and 2019,seed plant in different counties of Lishui,Zhejiang province was listed.The results show that there were 2785 species of wild seed plants belonging to 921 genera and 160 families in Lishui.The largest number of species was in Qingyuan county,with 2069 species belonging to 784 genera and 155 families,accounting for 96.88%,85.12%and 74.29%of that in Lishui,and followed by Longquan.At the family floristic element,the ratio of tropical and temperate zone in Lishui was 2.00,and the ratio of counties ranged between 1.84 and 2.09,indicating that the section level was mainly of tropical in nature.At the genera floristic element,the tropical/temperate value of Lishui was 0.83,and that of each county was 0.75-0.89,indicating that the temperate of the genera was slightly dominant.In terms of floristic division,it is generally bounded by Yunhe and Songyang,which could be divided into Western medium mountain area(I area)and Eastern low mountain area(II area).Area I could be divided into Qingyuan,Longquan sub area,Suichang sub area and Jingning sub area,and area II into Yunhe-Qingtian-Jinyun sub area,Songyang sub area and Liandu sub area.Each sub area was interrelated and had own properties,reflecting the complexity and diversity of Lishui seed plant flora.Longquan-Qingyuan sub area and Jingning sub area had the highest species diversity index.
