摘　　要：根据1997～2000年在东海(27°～32°N,128°E以西)的大型浮游动物垂直拖网调查结果,对陆架区毛颚动物多样性指数分布现状进行分析和探讨。结果表明:海区多样性指数以冬季最高,夏秋季次之,夏季第三,春季最低;平面分布格局大致呈近海向外海、北部向南部递增的趋势;多样性指数主要取决东海暖水、黑潮和东海沿岸水的消长,反映了不同季节群落结构时空分布的动态变化过程。The samples were collected with a large zooplankton net from bottom to surface in East China Sea(27°～32°N,East of 128°E)from 1997 to 2000. After analyzing and contrasting the diversity index (H') of Chaetognatha in continental shelf zone, the results showed that the highest value of diversity index was in winter, the following in autumn, the third in summer, and the lowest in spring.The distribution of diversity index was increased from offing to out sea, meanwhile from north to south. The value of diversity index was determined by the influence of warm water, Kuroshio water and coast-water of East China Sea reflecting the dynamic changing of spatial distribution of communities composition for different seasons.
