Season Dynamic of Plant Species Diversity in the Abandoned-field along the Jingjiang River near the Yangtze River

CHEN Zhong-yi et al (College of Gardening and Horticulture, Yangtze University, Jingzhou, Hubei 434025)  
The plant species diversity in the three years abandoned-field along the Jingjiang River near the Yangtze River was investigated. It was found that there were total 139 species, 100 genus, 39 families in Autumn, Winter, Spring and Summer. Shannon-Wiener index, Simpson index, Evenness index and Purity index were calculated according to species biomass values. The species diversity was the highest in Spring, next in Summer and Autumn, and the lowest in Winter. There was a very distinct different in plant species with seasons. The horizontal structure of plant species in plots also obviously changed in different seasons. These indicated that the plant species diversity of abandoned-field along the Jingjiang River had greater season fluctuation in early succession period.
