| 摘 要： | 以杭州湾南岸为例，探讨互花米草（Spartina alterniflora）潮滩底质的粒度及其分布特征。结果表明杭州湾南岸互花米草潮滩底质由黏土质粉砂、粉砂、粉砂质砂和砂质粉砂组成；从杭州湾口向湾内，互花米草潮滩底质中值粒径逐渐变粗，分选性变好；从低潮滩向高潮滩，互花米草潮滩底质的中值粒径逐渐变小，分选性变差。互花米草盐沼的形成使得潮滩底质粒度及其分布特征产生明显改变。

| Abstract: | Using south coast of Hangzhou Bay as a case study,the article researches on the granularity distribution characteristic of superficial sediments on Sparitina alterniflora flat.The results show that the sediments types on the flat are composed of clay-salt,salt,salt-sand and sand-salt.From Hangzhou Bay mouth to inside,median diameter of superficial sediments becomes greater while sorting become fine.From low flat to high flat,median diameter of superficial sediments increases gradually,but sorting becomes wo... |
