PLANT DIVERSITY OF WILD ELAEAGNUS MOLLIS COMMUNITIES IN HENAN PROVINCE, CHINA

Based on community vegetation survey data, the species composition, and important values of wild communities of Elaeagnus mollis in Jiaozuo and Sanmenxia were analyzed.The diversity of wild Elaeagnus mollis community in Henan Province was studied by using richness index, diversity index, evenness index and dominance index.The results showed that both sites exhibited the highest number of composite plant species, accounting for more than 14%, while herbaceous plant species were the most abundant, accounting for more than 50%.The important values of Elaeagnus mollis in the two communities are 45% and 39%, respectively.The richness indices of herbs and shrubs in the Jiaozuo sample plot were 3.87 and 3.25, respectively, indicating higher plant richness.The species evenness index of Sanmenxia community is low, while the dominance index is high.Based on the analysis results, suggestions for the protection of wild communities of Elaeagnus mollis were proposed.
