| 摘 要： | 基于2004年3月本底调查和2007年5月以及2010年8月跟踪调查的结果，对雷州乌石人工鱼礁渔业资源增殖效果进行了初步评价。结果表明，投礁后2007年和2010年礁区海域游泳生物种类数分别是投礁前的1.50倍和2.15倍；对比区海域游泳生物种类数分别是投礁前的1.27倍和2.00倍。投礁后礁区海域游泳生物资源密度分别是投礁前的2.13倍和3.00倍；对比区海域游泳生物资源密度分别是投礁前的0.46倍和1.96倍。投礁后，礁区和对比区海域的Pileou均匀度指数、Shannon-Winener多样性指数、Margalef种类丰富度指数均明显高于投礁前。投礁后，礁区和对比区海域鱼类成为第一优势种类群，在礁区还新增了一些经济种类。表明人工鱼礁投放后，礁区生产力得到了提高，群落结构变得复杂而稳定，渔业资源增殖效果和生态经济效益提升已有良好的体现。

| Abstract: | Resources multiplication was evaluated preliminarily based on 3 surveys carried out in March of 2004, May of 2007 and August of 2010 respectively. The results show that: after the development of artificial reef (ARs) in reef area, its species number was 1.50 times in 2007 and 2.15 times in 2010 of the number in background survey. The species numbers in control area were 1.27 times in 2007 and 2.00 times in 2010 of the number in background survey. Resources density in ARs area became 2.13 times in 2007 and 3.00 times in 2010 as many as in 2004. Resources densities in control area were 0.46 times in 2007 and 1.96 times in 2010 of density in 2004. Pileou uniformity index, Shannon Winener diversity index and Margalef species richness index increased gradually after ARs were deployed in both ARs area and control area. Fish has become the dominant species in both ARs area and control area after ARs were deployed. Some kinds of economic species which did not appear in background survey became normal species in tracking surveys. It is concluded from those results that the fishery productively in ARs area has improved a lot, and the community structure has became multiplication and stabilization. The resources multiplication effect and economic effect of ARs in Wushi Leizhou have been proved to be efficacious. |
