摘　　要： 根据2009年7月广东省柘林湾海域拟建溜牛人工鱼礁区海域和对比区海域本底调查所获资料,从水文、水质、底质、生物环境等方面分析了在拟建礁区建礁的优越性。结果表明,柘林湾溜牛拟建人工鱼礁区相对于对比区具有明显的建礁优越性:流速较平缓,投礁后礁体所受到的波流影响较小、稳定性较强;拟建礁区的海水透明度高于对比区,更适合营光合作用的浮游生物和礁体附着生物生长;各站位pH值的平面分布和垂直分布都比较均匀;海水质量基本达到国家二类海水水质标准;表层沉积物类型主要为细砂、粘土-砂质粉砂、粉砂质砂和粘土质粉砂,属于硬质底质泥沙底,可减缓礁体投放下沉时的冲击力,投礁后礁体稳定性较强;浮游植物、浮游动物和底栖生物的栖息密度和生物多样性均高于同期调查的对比区;拟建礁区游泳生物的栖息密度明显比对比区高;鱼卵仔鱼数量较多;拟建礁海域以前是良好的渔场,附近无工业废水排放。因此,在柘林湾溜牛拟建礁区建礁是可行的。 In accrodance with the results of the investigation of the coastal area which deploying artificial reef in Liuniu of Zhelin bay in Guangdong province in July 2009, analysis on the superiority of deploying artificial reef was carried out on hydrological and quality, benthic matter and biological environment etc. Compared with the comparison district, the area which intended to deploying artificial reef had obvious superiority, the velocity of seaflow was mild, when the reef was put into this areas, the impact of the sea currents was small and the stability of the artificial reef must be great. The sea diaphaneity of the area of deploying artificial reef was higher than the comparison area, suitable for the plankton and fouling organisms which can carry out photosynthesis on artificial reef growth. The planar distribution and vertical distribution of pH values in all stations were relatively uniform. The water quality had basically reached the Grade II standard of Sea Water Quality Standard （GB-3097-1997）. Types of surface sediments were mainly sand, clay-sandy silt, silty sand and clayey silt, substrate which the bedload has covered was hardness. It can weaken the wallop when the artificial reef sinking, and augment the stabilization. Stocking density and biological diversity of zooplankton, phytoplankton and benthic orgnaisms in the areas of deploying artificial reef were higher than the comparative area. Stocking density of the nektons and the number of the ichthyoplankton in the areas of deploying artificial reef was more than the comparative area too. The fishery resource of area which intended to deploying artificial reef was rich in the history, with no emission of wasted water, and did not make heavy pollution. So it＇s feasible to deploy artificial reef in this area.
