山西历山自然保护区苔藓植物的后续研究

继2003年钟海秀对历山自然保护区苔藓植物作研究之后,本文再次对该区苔藓植物进行了采集鉴定,结果表明历山自然保护区有苔藓植物共计21科35属45种.与钟海秀的研究有10科24属42种不同,其中1科2属2种为山西省新纪录.区系成分以北温带成分为主,占总数的62.16%,温带亚洲成分次之,占16.22%.热带亚洲、旧世界热带等成分的少量存在,又反映了本区苔藓植物区系的热带残遗性和古老性,说明历山自然保护区苔藓植物区系成分具有由亚热带向暖温带过渡的明显特点.

Study on the Bryophyte of Lishan Nature Reserve in Shanxi

Following the study of bryophytes by Zhonghaixiu in Lishan Nature Reserve in 2003, the bryophytes were collected and identified in the area by author again, 45 species （including 3 varieties, 1 subspecies） were reported, belonging to 21 families and 35 genera, 1 family ,2 genera and 2 species are new records in Shanxi Province. The research has 10 families, 24 genera and 42 species different with Zhong＇ s. The statistical analysis of the geographical elements of its species reveals that it has an absolutely dominant majority of North temperate elements（62.16% ） and a proportion of Tropical Asian elements（ 16.22% ）, Tropical Asia, the Old World tropics and other ingredients present in small amounts, and also reflects the region＇ s tropical bryoflora relict and antiquity. This shows the transitional characteristics of the bryoflora of the reserve from the subtropical to temperate.
