春、秋季台湾海峡海-气CO2通量及其影响因素

于2014年的5月（春季）和9月（秋季）在台湾海峡及其邻近南海和东海海域,采用水气平衡法进行了2个航次的海表和大气pCO2连续走航观测,同时获取了海表温度、海表盐度、风速及气压等数据,并采用海-气CO2分压差减法估算了海-气CO2通量.结果显示,春、秋2个航次平均海表pCO2分别为387±16μatm和408±18μatm.温度是影响台湾海峡及其邻近海域海表pCO2的主控因子,水团混合和其他因素等也对海表pCO2有一定影响.2014年春、秋季节,对研究区域的海-气CO2释放通量的估算结果分别为0.11±1.60 mmol/（m2·d）和2.51±1.10 mmol/（m2·d）.台湾海峡海表pCO2既存在显著的季节变化,又存在较大的空间差异.国家海洋局第三海洋研究所基本科研业务费资助项目(海三科2011015);;厦门南方海洋研究中心资助项目(14GHS016NF16,14PST63NF27

Modeling Influence of Temperature and Salinity on Growth Rate of Larva in Noble Scallop,Chlamys nobilis(Reeve) by Response Surface Methodology(RSM)

采用中心复合设计(CEnTrAl COMPOSITE dESIgn,CCd)的试验设计法研究了温度和盐度2个环境因子对华贵栉孔扇贝幼虫生长的影响。同时采用响应曲面分析法及基于响应曲面基础之上的满意度函数法确立了生长的二次回归方程,同时进行优化处理得到温度与盐度的最佳组合。结果表明,在华贵栉孔扇贝幼虫生长过程中温度与盐度在一定的范围内的互作效应不显著,其中温度效应较为明显。温度对壳长瞬时生长影响的一次项效应和二次项效应均达到显著水平(P<0.000 1)。盐度对壳长瞬时生长影响一次项效应显著(P<0.000 1),然而,盐度对壳长瞬时生长影响的二次项效应达到显著水平(P<0.000 1)。分析响应曲面法优化温度和盐度对华贵栉孔扇贝幼虫壳长瞬时生长率的影响,其结果显示最佳温度与盐度组合为25.33℃与29.42‰,此条件下瞬时生长率为7.91%,其满意度函数值达到85.57%。在生产实践中,严格控制温度和盐度范围,使其在最优值范围内,将会显著提高苗种生产效率。In this study,the combined effects of temperature and salinity on the instantaneous growth rate(IGR) of larva in noble scallop,Chlamys nobilis,was evaluated using the central composite orthogonal quadratic design and the response surface methodology.The results showed that the linear effects of temperature on IGR was statistically highly significant(P<0.000 1);the linear effects of salinity on IGR was significant(P<0.000 1).The interactions between temperature and salinity on IGR was not significant;the quadratic effects of temperature and salinity on the IGR was highly significant(P<0.000 1);temperature was more important in influencing growth of larvaof C.nobilis.By applying the simultaneous optimization technique,the optimum factor combination,i.e.,25.33 ℃ and 29.42‰ was found out,at which the optimal IGR(7.91%)arrived simultaneously,with the desirability value as high as 85.57 %.It is anticipated that application of the optimal temperature-salinity combination to practice would improve the productive efficiency of C.nobilis.国家自然科学基金(31160528); 国家海洋公益性行业科研专项(201405020-5); 海洋公益专项科研基金(201205021); 南海生物资源开发与利用协同创新中
