| 摘 要： | 对广东湛江红树林保护区高桥镇核心区的软体动物群落结构及其与红树植物群落、环境因子的关系进行了研究.结果表明,种群的相对重要性指数存在着季节差异,一些物种在不同季节数量有较大的变化.相同站位不同季节之间软体动物群落结构差异显著(p<0.05),并且存在显著的正相关关系(p<0.05).季节、底质、潮位线和红树植物群落等是决定软体动物群落结构的主要因素.利用生物量丰度比较法对广东德耀村红树林剖面进行污染评价,结果显示冬季受轻度污染,春、夏和秋季受中度污染.

| Abstract: | The molluscs fall structure were studied in Gaoqiao town core area of Zhangjiang Mangrove Nature Reserves,Guangdong,China.The indices of relative importance(IRI) of molluscs species is different in different seasons.The quantity of some molluscs have the bigger variety during different seasons.The fall structure of same stations during different seasons is obviously different(p<0.05)and positive correlation with each other(p<0.05).Season,the bottom quality,the tide line and the mangrove fall characteristic are the main factors that decide the fall structure of molluscs.Make use the ABC curve method to evaluate the pollution of the mangrove,it shows the mangrove of deyao village is polluted at light degree during winter,while at medium degree during the other seasons. |
