摘　　要：根据浙江省海洋水产研究所的监测资料,对2003～2006年浙江机轮围网渔获量的时空分布进行了研究与分析,结果表明:近年来,东海海域是浙江机轮围网的主要作业渔场,其渔获量重心呈逐年向外移动的趋势,外移的原因除与复杂的渔场环境因素相关外,还与近年来浙江群众传统灯光围网与2006年深水灯光围网的迅猛发展有关;中心渔场为高渔获量与高CPUE区,主要分布于33°～35°N、124°～125°E,26°～28°N、123°～125°E海域。Based on the monitoring data from the marine fisheries research institute of Zhejiang Province, the distribution of catch weight for purse seineing of Zhejiang Province was analyzed. The results showed that the East China Sea area was the main fishing ground, and the catch weight center was expanding to deep sea year by year. The reasons were both the over-developed traditional light seining in resent year and deep-water light seining in 2006 of non-national company fisheries. The fishing ground center was both the high catch weight area and the high CPUE area, mainly distributed in 33^o-35^oN、124^o～125^oE,26^o～28^oN、123^o～125^oE from 2003 to 2006.
