| 摘 要： | 对湘潭市郊菜地生态系统冬季期间杂草植物群落的物种多样性进行了初步研究，共出现18种，分属于10科15属，物种丰富度为9-15；Simpson指数为0.6401-0.7451；Shannon-Wiener指数为1.4852-1.7000；均匀度指数为0.5791-0.7145。结果表明：离市中心越远，物种多样性程度越高。

| Abstract: | The species diversity of weeds community of vegetable ecosystem is high in Xiangtan suburb fallow during winter season. Based on the total of the plots ,18 species which belong in 10 family, 15 genus were found. The result of diversity index is: the richness index is 9-15; the Simpson index is 0 6401-0 7451; the Shannon-Wiener index is 1 4852-1 7000; the evenness index is 0 5791-0 7145.The results show that the farther the vegetable plot is from city, the higher the species diversity is. |
