Study on Plant Diversity and Community Characteristics in Different Habitats of Huangpi Lake
[Objective]To study the plant community species diversity change in different habitats of Huangpi Lake wetland.[Method]Huangpi Lake wetland terrestrial plants,amphibious plants and aquatic plants as the research object,the different habitat plant community species diver-sity characteristics and the main dominant species community were analyzed by the line survey and inspection method.[Result]A total of 306 species plants were investigated belonging to 218 genera of 78 families,including 225 terrestrial plants and 165 species in 60 families;amphibi-ous plants were investigated to 199 species,belonging to 48 families and 134 genera;aquatic plants were surveyed to 32 species,belonging to 16 families and 24 genera.The difference in species composition between terrestrial and amphibious plants was not significant,but the composi-tion of the aquatic plant species and the other two habitats varied significantly.In terms of plant diversity,terrestrial and amphibious ecotone had higher species diversity than aquatic plants.Among them,the diversity index of terrestrial and amphibious plants was not significantly different,but the Shannon-Wiener index,Pielou evenness index and Margalef richness index of plants in both habitats were higher than those of aquatic plants,the Simpson index of aquatic plants was higher than that of terrestrial and amphibious interlaced plants.From the perspective of commu-nity characteristics,the terrestrial and amphibious plant communities of Huangpi Lake wetland were mainly dominated Compositae,Gramineae and Fabaceae plants.The aquatic plant community mainly had Gramineae,Nymphaeaceae and Trapaceae plants as the dominant species.[Con-clusion]Through the improvement and regulation of plant habitat,plants can effectively regulate the living environment and promote the level of species diversity.
