| 摘 要： | 为了解海岸滩涂围垦对沿海生态系统的影响,采用大型底栖动物群落来进行影响评价.对珠江口伶仃洋西海岸的6个自然滩涂和5个围垦滩涂的大型底栖动物进行比较研究,采用4种生物指数、聚类分析(CLA)及非度量多维测度排序(NMS)对其进行群落特征分析.结果显示:自然滩涂底栖动物种类数平均7.5种,栖息密度386.63 ind m-2,生物量15.593 6 g m-2,均普遍高于围垦滩涂.滩涂围垦可造成滩涂生境改变,从而导致底栖动物群落结构简单,生物组成单一,群落相似性较低.因此必须科学制定围垦方式并进行围垦后生态保护,在满足用地需求和生境保护之间取得平衡.图5表3参24

| Abstract: | To investigate the effect of reclamation on tidal flat ecosystem,samples of macrobenthos were collected from six natural tidal flats and five reclaimed tidal flats in the Pearl River Estuary,Guangdong,China.Methods of biotic indexes,cluster analysis(CLA) and non-metric multidimensional scaling(NMS) were used to analyze the characteristics of the macrobenthic community.Totally,7.5 species were indentified in the natural tidal flats.Population density was 386.63 ind m-2 and biomass was 15.593 6 g m-2 in the n... |
