Ecological Study Of Wetland Plant Community In Shanxi Wenyuhe Wetland National Park

This paper is about the vegetation in Shanxi Wenyuhe National Wetland Park.The vegetation and habitat in this region were thoroughly investigated by line survey method and quadrat survey method.The flora and quantitative ecological are analyzed based on the plant list of the Shanxi Wenyuhe National Wetland Park.It will provide some necessary basic data biodiversity conservation,restoration and reconstruction in the wetland park.1.There are 337 species of plants in the Wenyuhe National Wetland Park in Shanxi,which belong to 68 families and 206 genera.Among them,there are about 5 families,5 genera and 7 species of pteridophyte,and 63 families,201 genera and 330 species of seed plants.1 families,3 genera 4 species of gymnosperms,and 62 families,198 genera 326 species of angiosperms.There are 42 families,104 genera and 138 species of wetland plants,including 1 families,3 genera 3 species of gymnosperms,and 41 families 103 genera 135 species of seed plants,31 families 86 genera 115 species of dicotyledonous plants,10 families 17 genera 20 species of mono cotyledon.2.The seed plant flora of Wenyuhe National Wetland Park in Shanxi can be divided into 4 types and 1 variants.The genus level can be divided into 13 classes.Among the floristic components of the family class,there are 35 families belonging to the widespread type,accounting for 55.55%of the total number of general families and the highest proportion.Among the components of the genus class,there are 141 genera in the temperate element,accounting for about 70.14%of the total number of genera and significant advantages.3.There are 2 species of rare and endangered protected plants in the list of rare and endangered plants in China,8 second class national protected species of wild plants in Shanxi Wenyuhe National Wetland Park.One belongs to the in the rare and endangered plants in Shanxi,and 4 species of plants are in the red list of Chinese species.4.The seed plants in the Shanxi Wenyuhe National Wetland Park can be divided into 6 types according to the plant life type,of which there are 42 species of trees,29 shrubs,8 vines,116 species of medium herbs,127 species of wet herbaceous plants and 8 species of aquatic herbaceous plants.Among them,the number of humid herbaceous plants is relatively high,a total of 135 species,accounting for more than half of the total number of herbaceous plants,accounting for 40.91%of the total number of seed plants.5.Adopting TWINSPAN,dividing the plots into 9 associations.There are Comm.Typha orientalis+ Alisma orientale,Comm.Triarrhena sacchariflora,Comm.Phragmites australis,Comm.Larix principis-rupprechtii-Dendranthema chanetii+ Carex lanceolate,Comm.Pinus tabulaeformis-Rosa bella+ Spiraea pubescens-Fragaria orientalis+ Carex lanceolate,Comm.Fragaria orientalis+Potentilla anserine,Comm.Parnassia palustris+Fragaria orientalis,Comm.Poa annua+ Fragaria orientalis,and Comm.Hippophae rhamnoides-Poa annua+Heteropappus altaicus.6.DCA sorting chart of the sample and species reflects the main factors that determine the distribution pattern of the vegetation community in the Wetland Park,that is,the soil water content.The difference of soil water content affects the distribution of plants,and then affects the composition and distribution of the plant communities.It provides different natural landscapes for the wetland park.Ordination map did not significantly reflect the relationship between community and altitude.
