中文摘要	2005年夏季对长江口及毗邻海域(长江口、杭州湾和舟山海域)的40个站位进行了底栖生物的分类、组成、丰度、生物量以及多样性的研究.底栖生物共监测到86种,其中以长江口底栖生物种类最多(62种),其次为舟山海区(44种),杭州湾最少(5种);全海域底栖生物生物量平均9.55g/m~2,其中以舟山海区最高(12.45 g/m~2),长江口次之(8.52 g/m~2),最低为杭州湾(0.53 g/m~2);栖息密度平均为86个/m~2,其中以长江口最高(138个/m~2),舟山海区次之(33个/m~2),杭州湾最少(4个/m~2);各海区底栖生物多样性指数以舟山海区最高(1.28),长江口和杭州湾多样性指数均小于1,尤其是杭州湾仅为0.33;底栖生物的沙漠化程度较重,长江口、杭州湾及舟山海区生物量为零的站位分别占了31.2%、33.3%、13.3%.将以上结果与近十年来的积累调查资料比较显示,底栖生物生存环境仍较恶劣,长江口和杭州湾海域仍有三分之一的区域呈现沙漠化,但这种恶化趋势已得到初步遏制.
英文摘要	The benthos in the Changjiang Estuary and adjacent sea area at 40 sites ( the whole study area was divided into three main regions, the Changjiang Estuary, Hangzhou Bay and Zhoushan sea area ) were investigated by taxonomy and calculating the composition, abundance, biomass and diversity indices in the summer 2005. 86 species of benthic animals were collected. The average of benthic biomass in the study area was 9.55 g/m~2. The averages in three regions were 12.45 g/m~2 in Zhoushan sea area, 8.52 g/m~2 in the Changjiang Estuary and only 0.53 g/m~2 in Hangzhou Bay, respectively. As for abundance of benthos, the total average of inhabiting density was 86 inds/ m~2.Thereamong, the density is the highest (138 inds / m~2 ) in the Changjiang Estuary and the densities in Zhoushan sea area and Hangzhou Bay are 33 inds / m~2 and 4 inds / m~2, respectively. The benthic diversity index in Zhoushan sea area was 1.28, but both the Changjiang Estuary and Hangzhou Bay the diversity index were less than 1, especially Hangzhou Bay (0.33). Compared with the data of last 10 years, these figure showed that the desertification of benthic environment in the study area was still severe, all benthic species were absent in about one third of the study sites in the Changjiang Estuary and Hangzhou Bay. Fortunately, the trend of deterioration was contained slightly.
