摘　　要：为了解修复后三门县健跳港牡蛎礁的净水功能,在调查了礁体中牡蛎种类和比例的基础上,测定了礁体中3种牡蛎的滤水率并探究了规格、水温对牡蛎滤水率的影响,最后在摸清牡蛎个体滤水率、比例、密度、牡蛎礁面积等参数的基础上计算了牡蛎礁的滤水量。结果显示,不同规格的3种牡蛎的滤水率均有显著性差异(P<0.05):熊本牡蛎(Crassostrea sikamea)和近江牡蛎(C.ariakensis)的小规格个体有最大滤水率,分别为(6.94±2.64)、(0.87±0.23)L·g^(-1)·h^(-1);香港牡蛎(C.hongkongensis)中规格个体滤水率最大,为(1.83±1.07)L·g^(-1)·h^(-1)。水温仅对熊本牡蛎的滤水率有显著影响(P<0.05),在20℃时达到最大滤水率(2.48±1.62)L·g^(-1)·h^(-1)。根据本研究中获得的公式计算得到浙江省三门县2019年和2020年人工修复礁体的滤水量分别达到16613.02、26016.56 L·h^(-1)。研究表明,三门县修复后的牡蛎礁具有较强的净水功能。研究结果可为今后牡蛎礁的修复工作提供数据支撑。Oyster reefs are important coastal habitats,and they have various ecosystem functions,but their area has declined by about 85%due to overfishing,environmental pollution and other reasons.To understand the water purification function of Jiantiao Bay oyster reefs in Sanmen County,the types,proportions and the filtration rate of oysters[Crassostrea ariakiensis(CA),C.hongkongensis(CH),and C.sikamea(CS)]in the reefs were analyzed,the effects of temperature and specifications on oyster filtration rate were explored,and the filtration of artificially restored oyster reefs were estimated.This study measured the filtration rates of three types of oysters with different individual sizes(large,medium,small)and under different water temperatures(10℃,20℃,25℃,30℃).The research results indicated that individual size had a significant impact on the filtration rate of CA,CH,and CS(P<0.05):CS and CA had the maximum filtration rates at small size,which were(6.94±2.64)L·g~(-1)·h~(-1)and(0.87±0.23)L·g~(-1)·h~(-1),respectively;CH reached the maximum filtration rate of(1.83±1.07)L·g~(-1)·h~(-1)at medium size.In the large and small size experimental groups,the order of filtration rate was:C.sikamea>C.ariakiensis=C.hongkongensis(P<0.05);in the medium size experimental group,the order of filtration rate was:C.sikamea=C.hongkongensis>C.ariakiensis(P<0.05).Results from two-way ANOVA demonstrated that species significantly affected the filtration rate of oysters,while sizes also had influence on the filtration rate of oysters.The water temperature had a significant impact on the filtration rate of CS(P<0.05),reaching the maximum filtration rate(2.48±1.62)L·g·h~(-1)at 20℃.The water temperature did not have a significant effect on the filtration rate of CA and CH(P>0.05).At water temperatures of 10℃,20℃,and 25℃,the order of filtration rate was:C.sikamea>C.ariakiensis=C.hongkongensis(P<0.05);at a water temperature of 30℃,the order of filtration rate was:C.sikamea>C.ariakiensis>C.hongkongensis(P<0.05).C.hongkongensi
