| 摘要: |
| 本文利用睛空大气辐射传输分光参数化模式,讨论了到达太湖水面太阳总辐射中光合有效成分所占比例的日变化状况。辐射传输计算所涉及的气象参数采用无锡地区气象站资料;水体反射仅考虑有风浪状况下的水平Fresnel反射。两次湖面实测太阳总辐射日变化曲线与计算值对比分析表明,计算结果基本上能反映晴空条件下太湖水面辐射状况。本文结果对利用总辐射值估算水体生态研究中感兴趣的光合有效成份有-定参考价值。 |

| Abstract: |
| According to the spectral model for transferring of solar radiation in cloudless atmosphere, the solar irradiance at the surface of Taihu Lake is computed and ratio of photosynthetically available radiation (PAR) to the total radiation investigated.Also,the numerical computations are carried out by comparison with the twice 24-hour field observations;and it is shown that the computed results are the enveloping curves of the measured data.In the numerical computation,the meteorological data,such as surface pressure and wind speed,from the meteorology stations in Wuxi region are adopted;and in the treatment of reflection of water-surface.the effect of wave is taken into consideration. |
