大亚湾浮游植物粒级结构对温排水和营养盐输入的响应*

Abstract

Abstract:

Marine ecological effects induced by thermal discharge of nuclear plants in Daya Bay are attracting increasingly attention. Based on in situ data and laboratory experiments, distribution characteristics of phytoplankton size structure within the thermal-discharge-affected area and their responses to warming and nutrients input were explored. The results indicated that phytoplankton growth could be promoted by moderate warming but inhibited in extremely high temperature (36ºC). Chl-a concentrations near the outfall of thermal discharges were obviously low in both summer and winter. There were seasonal discrepancies between two important environmental factors, i.e., warming and nutrient enrichment, on their contributions to phytoplankton growth based on simulation results. Nutrients inputs showed more obvious impacts on phytoplankton than temperature in summer, and vice versa in winter. The increasing proportion of small-size phytoplankton (< 20μm) might be induced by warming and/or nutrient enrichment in Daya Bay, which confirmed the miniaturization trend within the plankton community and indicated its potential impacts on energy flow and material cycle, ecosystem stability, and production of marine fisheries in the bay.

Key words: phytoplankton, size structure, thermal discharge, nutrients, Daya Bay
