    • 摘要: 根据2018年胶州湾20个站位4个季节的大型底栖动物调查资料,利用Brey(2001)模型对大型底栖动物群落的次级生产力进行了估算,并对影响群落次级生产力的因子进行了研究.结果表明:胶州湾大型底栖动物年平均丰度为1904.80ind.·m-2,年平均生物量为87.0188g·m-2,群落年次级生产力为45.2843g·m-2·a-1.大型底栖动物群落次级生产力呈现出由胶州湾中部向南北两侧增大的趋势.养殖种菲律宾蛤仔(Ruditapes philippinarum)和长牡蛎(Cras-sostrea gigas)的次级生产力占胶州湾大型底栖动物次级生产力的89.12%.沉积物中叶绿素a含量和底盐是影响群落次级生产力的重要环境因子.

    • 摘要: 为研究福建省闽江口潮间带大型底栖动物次级生产力的时空变化,于2014年1 1月-2015年8月对闽江口大型底栖动物进行了4个季度的调查研究.在获得3条断面大型底栖动物物种数、密度和生物量的基础上,利用Brey经验公式计算年平均次级生产力(P).研究结果显示:闽江口4个季度共获得大型底栖动物63种,其中优势类群为多毛类.闽江口潮间带大型底栖动物年均次级生产力为6.13 g (AFDW) ·m-2·a-1 (AFDW,去灰分干重,ash-free dry weight).在季节分布上,次级生产力最高值出现在夏季,为11.04 g (AFDW)·m4·a-1,最低值出现在冬季,为2.25 g (AFDW) ·m-2·a-1;在空间分布上,次级生产力最高值出现在P03断面,为10.23 g (AFDW)·m4·a-1,最低值出现在P01断面,为2.54 g (AFDW)·m-2·a-1.大型底栖动物年均P/B值(B=Biomass,生物量)为2.31 a-1,最高值出现在春季,为3.17 a-1,最低值出现在夏季,为1.74 a-1;且P02断面的P/B值高于其他2条断面.Pearson相关分析结果表明,次级生产力与温度呈显著正相关,P/B值与盐度呈显著正相关但与pH呈显著负相关.因此,环境因子在一定程度上影响着该区域大型底栖动物的次级生产力.闽江口大型底栖动物群落组成中以个体小、生活史短、繁殖快的小型甲壳类蜾赢蜚(Corophium sp.)为主,使该潮间带区域的P/B值高于其他临近潮间带区域的调查结果.

    • 摘要: 渔山列岛于2008年成为国家级海洋生态保护区,为了解渔山列岛保护区内潮间带软体动物次级生产力的时空变化.于1982年和2010年的3个季节(春、夏、冬)在渔山列岛进行潮间带软体动物调查,采用多元统计分析软体动物时空差异,以Brey经验公式计算分析软体动物次级生产力(P值,P/B值).结果表明,年际间物种食性结构发生了明显的改变,1982年潮间带软体动物对次级生产力贡献率最大的物种有单齿螺(Monodonta labio)、锈凹螺(Chlorostoma rustica),占软体动物总次级生产力的42.88%,2010年潮间带软体动物对次级生产力贡献率最大的物种有覆瓦小蛇螺(Serpulorbis imbricata)、条纹隔贻贝(Septifer virgatus),占软体动物总次级生产力的75.96%.1982年,年均栖息密度为2758ind/m2,年均生物量为2100.26g/m2,年均次级生产力为240.04g/(m2·a),年均P/B值为0.63a-1;2010年,年均栖息密度为699ind/m2,年均生物量为1101.85g/m2,年均次级生产力为94.82g/(m2·a),年均P/B值为0.55a-1.多因素方差分析表明软体动物次级生产力年际间差异显著(F=5.761,P<0.05),季节间和潮位间差异都不显著(F=0.135,P>0.05;F=2.076,P>0.05),P/B的值较低,表明该海域软体动物世代更替速度较慢,2010年的P/B值(0.55a-1)低于1982年的P/B值(0.63a-1),表明近30年来群落结构受到影响.%Yushan Islands,East China Sea,is a national marine ecological protection zone established in 2008.To understand temporal and spatial changes in secondary productivity of mollusks in the intertidal zone of the protection area,we conducted investigations at intertidal mollusks in the area in 1982 and 2010 in spring,summer,and winter.Multivariate statistical analysis was used to reveal temporal and spatial differences of mollusks,and the Brey empirical formula was adapted to analyze the secondary (P value,P/B value) productivity.The results show that the species structure of food habit changed significantly.In 1982,the species of the highest contribution rate to the secondary productivity were Monodonta labio and Chlorostoma rustica,taking 42.88% of the total.In 2010,the highest contributors were Serpulorbis imbricate and Septifer virgatus,taking 75.96% of the total.The annual average values were,in 1982:density 2758ind/m2,biomass 2100.26g/m2,secondary productivity 240.04g/(m2.a),and P/B 0.63a-1;in 2010,they were 699ind/m2,1101.85g/m2,94.82g/(m2·a),and 0.55a-1,respectively.In addition,result of multivariate analysis of variance shows that the interannual secondary productivity of mollusks varied significantly (F=5.761,P<0.05),but not in season and in tidal space (F=0.13,P>0.05;F=2.076,P>0.05).The small P/B ratios indicate that the sea mollusks generation replacement was slow,and slower in 2010 (0.55a-1) than in 1982 (0.63a-1),indicating that the community structure became worsened in the past nearly 30 years.

    • 摘要: 利用1988年1月和7月,2004年3月、5月、9月和12月,2008年3月、5月、9月和12月以及2015年2月、8月、11月和12月在大亚湾海域开展的共计14航次、200站次的大型底栖动物调查结果,根据Brey经验公式计算大型底栖动物次级生产力次级生产力与生物量的比值(P/B值),分析近30年次级生产力变化特征。结果表明:1)以去灰干质量(ash free dry mass,AFDM)计,大亚湾4个时段大型底栖动物次级生产力分别为7.44 g·(m2·a)–1、11.34 g·(m2·a)–1、4.91 g·(m2·a)–1和2.93 g·(m2·a)–1,P/B值分别为0.76 a–1、0.86 a–1、0.79 a–1和0.47 a–1,均呈1988—2004年升高、2004—2015年降低的趋势。2)各类群次级生产力和P/B值变化趋势存在一定差异。其中软体动物、多毛类、甲壳类次级生产力和P/B值呈1988—2004年升高、2004年后降低的趋势;棘皮动物则均呈持续降低的趋势。3)综合各类群次级生产力平面分布图,湾顶西北部和大鹏澳附近海域变化明显。相关性分析显示,底栖动物次级生产力与海水无机氮、磷酸盐、溶解氧浓度和沉积物有机碳含量显著相关。

    • 摘要: 利用1988年1月和7月,2004年3月、5月、9月和12月,2008年3月、5月、9月和12月以及2015年2月、8月、11月和12月在大亚湾海域开展的共计14航次、200站次的大型底栖动物调查结果,根据Brey经验公式计算大型底栖动物次级生产力次级生产力与生物量的比值(P/B值),分析近30年次级生产力变化特征.结果表明:1)以去灰干质量(ash free dry mass, AFDM)计,大亚湾4个时段大型底栖动物次级生产力分别为7.44 g·(m2·a)–1、11.34 g·(m2·a)–1、4.91 g·(m2·a)–1和2.93 g·(m2·a)–1,P/B值分别为0.76 a–1、0.86 a–1、0.79 a–1和0.47 a–1,均呈1988—2004年升高、2004—2015年降低的趋势.2)各类群次级生产力和P/B值变化趋势存在一定差异.其中软体动物、多毛类、甲壳类次级生产力和P/B值呈1988—2004年升高、2004年后降低的趋势;棘皮动物则均呈持续降低的趋势.3)综合各类群次级生产力平面分布图,湾顶西北部和大鹏澳附近海域变化明显.相关性分析显示,底栖动物次级生产力与海水无机氮、磷酸盐、溶解氧浓度和沉积物有机碳含量显著相关.%Based on the survey data collected from 200 sampling stations by 14 cruises in Daya Bay of the South China Sea in 1988, 2004, 2008 and 2015, we analyzed the characteristics of the secondary productivity and P/B (secondary production/biomass) ratio of macrobenthos for nearly 30 years using Brey's empirical formula. The results show that: 1) Based on ash free dry mass (AFDM), the microbenthic secondary productivity and P/B ratio were 7.44 g·(m2·a)–1and 0.76 a–1in 1988, 11.34 g·(m2·a)–1and 0.86 a–1in 2004, 4.91 g·(m2·a)–1and 0.79 a–1in 2008, 2.93 g·(m2·a)–1and 0.47 a–1in 2015, respectively. The secondary productivity and the P/B ratio of macrobenthos increased during 1988?2004, then decreased during 2004?2015. 2) The secondary productivity and the P/B ratio of the main groups of macrobenthos in Daya Bay differed significantly. The variation of secondary productivity and P/B ratio of Mol-lusca, Polychaeta and Crustacean increased during 1988?2004, then decreased during 2004?2015, being consistent with the trend of the whole macrobenthos in Daya Bay. Different from the other groups, the secondary productivity and P/B ratio of Echinoderm showed a decreasing trend during 1988?2015. 3) Generally, the secondary productivity of the macrobenthos had obvious variation in the northwest of the top Daya Bay and Dapeng'ao Bay. The correlation analysis between macrobenthos community and environment-al factors indicates that the secondary productivity was significantly affected by the contents of inorganic nitrogen, phosphorus, dis-solved oxygen of seawater and organic carbon content of sediment.

    • 摘要: Samples of Corbiculafluminea (Müller,1774) were collected monthly from March 2011 to February 2012 in the Datong Lake to study its population dynamics and secondary production in its native environment.A total of 4,108 C.fluminea were collected and measured,with shell length (SL) ranging from 3.41 to 29.58 mm,and wet weight (WW) ranged from 0.005 to 10.03 g.The calculated SL-WW equation was log WW=-3.52+3.08 log SL (R2=0.97),which showed that the growth curve of C.fluminea followed a positive allometric pattern.The recruitment patterns peaked in one from March to April and the other one during the months of August to October.The mean annual abundance and biomass ((B)) were (2744-95) ind./m2 and (20.14±5.7) g AFDW/m2 (Ash Free Dry Weight,AFDW),respectively.The annual secondary production (P)was estimated to be 23.90 g AFDW/mLyear,resulting in a P/(B) ratio of 1.20/year and a turnover time of 298 days.The asymptotic maximum length (L∞),curvature parameter (K) and seasonal oscillation in growth rate (C) derived from the von Bertalanffy Seasonal Growth Formula (VBSGF) were 31.91 mm,0.45/year,.and 0.84,respectively.The slowest growth period was in January,and the potential lifespan (tmax) was estimated to be 4.44 years.The total mortality (Z),natural mortality (M) and fishing mortality rates (F) estimateddwere 1.68/year,0.89/year and 0.79/year,respectively.Its exploitation rate (E=0.47) indicated a slightly high exploited stock that needs some management intervention to maintain the sustainability of this fishery resource.%2011年3月至2012年2月,通过逐月调查的方式,分析了大通湖河蚬的种群动态,并采用体长频率分布法计算其次级生产力.调查共采集分析河蚬4108个,壳长(SL)和湿重(WW)范围分别为3.41-29.58 mm和0.005-10.03 g.大通湖河蚬SL和WW之间的关系为WW=-3.52+3.0810gSL(R2=0.97),表明其种群呈异速生长;繁殖高峰主要集中在3-4月和8-10月.河蚬的年平均密度和生物量((B),以无灰干重计,AFDW)分别为(274±95)ind./m2和(20.1±5.7)gAFDW/m2,年次级生产力(P)为23.90g AFDW/(m2.年),P/B系数为1.20/年,周转率为298d.基于VonBertalanffy季节生长方程估算的河蚬生长参数为:渐近壳长L∞=31.91mm,生长速率K=0.45,振幅C=0.84,冬季点WP=0.09,表明大通湖河蚬生长呈明显的季节性,1月生长速率最低.河蚬最长寿命(tmax)约为4.44年,年总死亡系数(Z)为1.68,自然死亡系数(M)为0.89,捕捞死亡系数(F)为0.79,年开发率(E)为0.47.结果表明大通湖河蚬资源处于过度开发状态,急需采取有效的措施对其资源进行合理保护.

    • 摘要: 基于国外大型底栖动物次级生产力的评估方法,结合国内研究现状,选取了3种Brey模型对胶州湾大型底栖动物的次级生产力进行估算,通过2015-2017年连续3个季度对胶州湾海域大型底栖动物的调查,最终结果表明:胶州湾大型底栖动物的次级生产力与其他海域相比具备较高的水平,次级生产力的季节性变化明显,其中夏季为最高;湾内高值区位于湾顶中部红岛以南到向西偏移至大沽河口和红石崖附近.分析发现历年来大型底栖动物群落的物种组成基本保持稳定,菲律宾蛤仔(Ruditapes philippinarum)资源的变化是造成次级生产力变化的最主要因素.研究推荐使用Brey(2012)模型来估算胶州湾大型底栖动物次级生产力,春、夏、秋季的估算结果分别为880.17、1 537.64、458.33 kJ/(m2·a).
