我们测试的假设，长期增亮的太阳辐射和水下光气候的变化将增加浮游植物的初级生产在春季在霞浦湖，日本。全球太阳辐射具有年代际波动特征，日本5月太阳辐射自20世纪90年代以来一直呈上升趋势。我们根据长期监测数据开发了一个深度综合初级生产力（gC m− 2 h −1）模型。基于光合作用-辐照曲线的模型阐明，由于太阳辐射和水温升高的综合影响，初级生产力从1992年的0.093 gC m− 2 h − 1增加到2019年的0.105 gC m− 2 h − 1，增加了13.2%。模型的敏感性分析表明，初级生产力对水质参数的影响最为敏感，即光衰减系数和营养盐对Pmax的影响。营养盐效应与颗粒有机碳氮比显著相关，表明浮游植物细胞氮素缺乏可能影响初级生产力。这些结果表明，长期春季太阳辐射和水温增加初级生产，但水质也控制初级生产。
We tested the hypothesis that long-term brightening of solar radiation and changes in the underwater light climate would increase the primary production of phytoplankton in the springtime in Lake Kasumigaura, Japan. Global solar radiation fluctuates on a decadal scale, and the solar radiation in May has been increasing since the 1990s in Japan. We developed a model of depth-integrated primary production (gC m−2h−1) based on long-term monitoring data. The model based on photosynthesis-irradiance curve clarified that primary production increased by 13.2%, from 0.093 gC m−2h−1in 1992 to 0.105 gC m−2h−1in 2019, because of the combined effects of solar radiation and water temperature increases. Sensitivity analysis of the model showed that primary production was most sensitive to water quality parameters, i.e. the light attenuation coefficient and nutrient effects onPmax. Nutrient effects were significantly correlated with the particulate organic carbon to nitrogen ratio, indicating that nitrogen shortage in phytoplankton cells may affect primary production. These results suggest that long-term springtime increases in solar radiation and water temperature increase primary production, but that water quality also controls primary production.
