| Through surveys of plants and vertebrates,this paper studies biodiversity in the Nianshan wetland park of Zhenghe County,Fujian province.There are 194 families,606 genera and 1062 species of vascular plants in the wetland park.Among them,ferns belong to 28 families,43 genera and 63 species;gymnosperms belong to 8 families,14 genera and 16 species;angiosperms belong to 158 families,549 genera and 983 species.There are 28 orders,71 families,139 genera and 193 species of vertebrates.Among them,fish belong to 5 orders,12 families,28 genera and 31 species;amphibians belong to 1 orders,4 families,6 genera and 17 species;reptiles belong to 3 orders,9 families,19 genera and 25 species;birds belong to 13 orders,35 families,68 genera and 97 species;mammals belong to 6 orders,11 families,18 genera and 23 species.The study shows that the biodiversity of Nianshan Wetland Park in Zhenghe County,Fujian province is rich,while most of the plants in wetland parks are hygrophyte,followed by emergent aquatic plant,and the other life forms are relatively few.Phyllostachys pubescens is the most common type of forest vegetation in wetland parks,widely distributed on the slopes of wetland parks.Wetland vegetation is mainly composed of the hygrophyte of Gramineae,Polygonaceae,Cyperaceae,Compositae,Scrophulariaceae,Ranunculaceae,Labiatae,Salix,etc.Evergreen broad-leaved forest or evergreen deciduous broad-leaved forest in the park belong to the top type or sub top type of vegetation succession in subtropical regions,which have reasonable forest structure and abundant biological species,and have important ecological significance for water conservation and soil and water conservation in the park and nearby mountain areas.This paper systematically investigated vertebrates in fish,amphibians,reptiles,birds,and mammals in wet areas.Consistent with the characteristics of freshwater fish fauna in Fujian province,fish are mainly composed of the fish complex of the river plain and the tropical plain fish fauna complex,and are mainly omnivorous,bottom and fish adapted to water.Birds are mainly dominated by oriental species. |
