摘 要：
研究了长江荆江段学堂洲一个 3年弃耕地的植物在春季、夏季、秋季和冬季的物种多样性。结果表明 :该地植物物种丰富 ,共有3 9科 ,10 0属 ,13 9种。根据生物量计算出的 4类物种多样性指数都反映出植物物种多样性大小顺序为春季 >夏季 >秋季 >冬季。该弃耕地上植物物种的季节性替代明显 ,水平结构在不同季节变化也大 ,即在该弃耕地演替的早期 ,植物多样性具有明显的季节波动

摘 要：
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.
