摘　　要：本文根据 １９９４～１９９５年间山东近海大面积底拖网探捕调查资料，对山东近海 ５～４０ ｍ水深范围内海胆的种类组成及生态分布状况等进行了初步分析研究。山东近海海胆共出现６种，其中经济价值较高的种类为光棘球海胆和马粪海胆。主要分布区：１）渤海中央水槽至长山列岛近岸水域；２）威海以东至成山头北部近岸水域；３）石岛近海；４）青岛以南至石臼所近岸水域。In accordance with the survey data of the large area bottom trawl exploratory fishing conducted in Shandong offshore between 1994 and 1995,the species composition and ecological distribution of sea urchin in waters of 5-40 m deep was analysed in this paper. Six species of sea urchin were found in Shandong offshore. Strongylocentroctus nudus and Hemicentrotus pulcherrimus were the species of economic value. They mainly distribute in 4 areas: 1 )waters from the centre trough in the Bobal Sea to Changshan Islands off shore ; 2) coastal waters from east of Weihai to north of Chengshantou ; 3 ) Shidao offshore; 4 )coastal waters from south of Qingdao to Shijiusuo.
