摘要
本文报道了辽宁省白石砬子国家级自然保护区苔藓植物251种,9变种,2亚种,3变型,其中中国新记录种2种,东北地区新记录属3个,新记录种10种.并就其苔藓植物群落其及区系成份和地理分布特征等作一初步分析探讨。
64 species,2 Varieties of liverwortas and 187 species,7 subspecies,2 varieties,3 forms of mosses are reported for the first time from the Mountain Baishilazi,Liaoning Prov.in present paper.Among them,2 species arc new to China,and 3 genera and 10 species new to Northeast China. The Bryophyta communities in Mt.Baishilazi could be divided into four main typies:(1)Hydrophytia;(2)Petrophytia;(3)Geophytia; and(4)Epixylophytia. An analysis of floral elements of Bryophytes in the mountain indicated that 250 species(94.4% of the Total)belong to the holarctic elements,of which 66 species(25%)to the East Asian elements and only 4 species(1.5%)to the palaetropic ones.Comparisions of the bryophytes in Mt.Baishilazi with those of Mt.Changbai,Mt.Huang,East China are discussed in detail.
