Abstract:

作者于1992年2、5、6、8和10月在象山港湖头渡,5月和6月在大佳河(港顶部)、西沪港(港中部)和横山(近港口区)4条断面潮滩进行了底栖微型藻现存生物量和初级生产力的观测研究.结果表明,潮滩表层叶绿素a浓度分布具有明显的空间区域性和时间变异性特征.港顶部的浓度高于港中部和近港口区;滩面表层的平均叶绿素a浓度,5月[(10.36±8.08)μg/g湿重]高于6月[(2.94±1.21)μg/g湿重].由于光的限制,沉积物中的叶绿素a主要分布在表层0~1cm,随深度的增加浓度下降,但其降解产物──脱镁叶绿素的浓度却增大.松软、平整、稳定的滩面有利于底栖微型藻类的生长,5、6月湖滩表层平均初级生产力(45.1±46.8)mg/(m2·h)(C).湖头渡潮滩叶绿素a浓度以夏季最高,春、秋季次之,冬季最低;初级生产力仍以夏季最高,春、冬季较低,秋季最低.
