Study on Vegetation Type,Flora and Diversity in Xinjizhou National Wetland Park
摘要
Abstract
In the spring and autumn of 2020,remote sensing image analysis and plant field survey and monitoring were carried out to fully un-derstand the vegetation type,flora,and species diversity characteristics of plant in Xinjizhou national wetland park,Nanjing,China.The results showed that vegetation accounted for 87.79%of the total area.Vegetation can be divided into three primary vegetation types(artificial vegeta-tion,semi-natural forest,natural grassland)and 16 secondary vegetation types.The study demostrated that there were 96 families,270 genera and 392 species.Among them,there existed ferns plants of 8 families,8 genera and 10 species,gymnosperms plants of 5 families,7 genera and 8 species,angiosperms plants of 83 families and 255 genera and 374 species.Poaceae,Asteraceae and Cyperaceae were the dominant families.The geographic distribution of the genera of plants existed 14 distribution types,and they were mainly in a tropical and temperate distribution.Monitoring results of vegetation sampling sites showed that the mean Shannon-Wiener diversity index was significantly higher in autumn than in spring.Among the 24 vegetation sampling sites,the Shannon-Wiener diversity index varied significantly,the mean Patrick richness index,Simp-son dominance index and Pielou evenness index did not differ significantly in spring and autumn,and showed a similar trend.关键词
