中文摘要：
为了建设獐子岛海洋牧场,拟在獐子岛海域范围为39°0′9″～39°0′58″N,122°55′1″～122°55′51″E处投放人工鱼礁,投礁前于2010年6月在拟投放人工鱼礁区域进行了本底调查.结果表明：该海域水深33～37 m,透明度为4.14 m,底质为硬泥底,海域的流速平缓,平均流速为31 cm/s,叶绿素a含量平均为1.68μ g/L,无机氮和活性磷酸盐分别为4.50、8.10 mmol/L,溶解氧和化学需氧量分别为10.22、0.2097mg/L,水质因子均符合国家Ⅰ类海水水质标准;浮游动物有8种,优势种为强壮箭虫、小拟哲水蚤和大同长腹剑水蚤,浮游植物有1 1种,优势种为中肋骨条藻和柔弱菱形藻,游泳生物有大泷六线鱼、云（射）和黄鲛鱇等.调查结果表明,该海域水质符合国家Ⅰ类海水水质标准,海域环境优良,是许多生物优良的生息场,适宜投放人工鱼礁.
英文摘要：
The ecological environment was surveyed and assessed in marine ranching area at Zhangzi Island in 39°0′9″-39°0′58″N and 122°55′1″-122°55′51″E where,an artificial reef is planed to be disposed on June in 2010.The results showed that the area surveyed had water depth value of 33-37 m and Secchi disc value of 4.14 m,the hard substrate bottom,mild flowing velocity with an average of 31 cm/s,average chlorophyll a of 1.68 μg/L,inorganic nitrogen level of 4.50 mmol/L,dissolved oxygen level （DO） of 10.22 mg/L,phosphorus level of 8.10 mmol/L,and COD of 0.2097 mg/L,within the government standards of the First Class Marine Water Quality.There were 8 zooplankton species,with dominant species of Sagitta crassa,Paracalanus parvus,and Oithona similis,11 phytolankton species,with dominant species of green alga Skeletonema costatum and diatom Nitzschia delicatissima,and nektons fat greenling Hexagrammos otakii,cloudy benny Enedrias nebulosus,and yellow goosefish Lophius litulon.The findings indicate that the area is good in water quality,and suitable habitats for many living things,so the optimal for artificial reef construction.
