利用2010-2011年中街山列岛水域4个季节的渔业资源调查资料,分析了该水域虾类种类组成和资源密度,并探讨了底层温度、底层盐度和水深对虾类数量分布的影响。结果表明,共鉴定虾类20种,隶属于9科18属;广温广盐种无论在种类数还是尾数密度与生物量均占主导地位;虾类生物量和尾数密度在季节分布上,以冬季最高,不管是生物量还是尾数密度,冬季均与春、夏和秋三季呈显著差异（P〈0.05）;平面分布上,生物量与密度指数总体上呈南北高、中间低,东部高西部低的特征;生物量与平均底温显著相关（P〈0.05）,与平均底盐和水深相关性较差（P〉0.05）;葛氏长臂虾、细巧仿对虾、中国毛虾、日本鼓虾和中华管鞭虾为四季的优势种为,且均属广温广盐种。

In this paper, the composition and resource status and its relationship with environmental variation of shrimps were analyzed by fishery investigation from 2010 to 2011 in the water of Zhongjieshan islands. The results showed that there were twenty species belonging to 18 genus, 9 families of shrimps. For percentage of number of species, the number abundance density and biomass, eurythermal and euryhaline species all occupied the dominant position. On seasonal distribution, both the biomass and number abundance density in winter reached the highest, and those in winter were significantly different from that in any other seasons (P〈0.05). On spatial distribution, both the biomass and number abundance density in northern andsouthern area were higher than those in central area, and those in the eastern were higher than in the western. By correlation test, the biomass was significant related with sea bottom temperature (P〈0.05) but not related with sea bottom salinity and depth (P〉0.05). In survey waters all the dominant species including Palaemon gravieri, Parapenaeopsis tenella, Acetes chinensis, Alpheus japonicus, Solenocera crassicornis were eurythermal and euryhaline species.
