界首两湾国家湿地公园维管植物区系研究
A floristic study on vascular plants in Jieshou Liangwan Wetland Park
摘要
Abstract
Based on field investigation and literatures, the composition and flora of vascular plants were studied in Anhui Jieshou Liangwan Wetland Park. The results showed that there were 216 species of wild vascular plants, belonging to 59 families and 150 genera (230 species of vascular plants, being member of 61 families and 162 genera) and including 4 species of ferns in 4 genera and 4 families. These vascular plants were rich in oligotypic families and genera, accounting for 52.5％ of families, and 78.2％ of generas in total respectively. There were three dominant families i, e. Leguminosae, Compositae and Gramineae. There were 9 genera and 16 species in Leguminosae, 20 genera and 30 species in Compositae, 21 genera and 28 species in Gramineae. The 59 vascular plant families could be classified into 5 areal-types and 2 subtypes. Among them, Cosmpolitan elements were the most dominant one. Tropical distribution sections accounted for 81.3％ in addition to Cosmpolitan families. The 150 vascular plant generas could be devided into 12 types and 8 subtypes. Temperate type elements had the highest proportion, which was 42.7％. From the perspective of genera and families, the flora has the characteristics of both temperate and tropical, accorded with the truth that the wetland park located between the warm temperate zone and north subtropical zone.关键词
