摘要
通过2003年1月份对珠江口水体中的光谱分布,衰减系数,光反射率以及浮游植物对光吸收的研究结果显示:红光、蓝光衰减较快,绿光衰减较小,越向水体下层,绿光的相对含量越大,这主要是由于浮游植物在蓝光和红光波段处有吸收峰以及非藻颗粒对蓝紫光吸收较多的缘故;从总体来讲,绿光的辐亮度漫反射率(Lu/Ed)较蓝光和红光大:在上层水体中有一个反射强度较大的区域,可能是由于浮游植物在这一层的分布较多。
The present paper studied the light spectrum distribution, vertical attenuation coefficient, light reflection and light
absorbance of phytoplankton in waters of the Pearl River mouth, Results showed that the attenuation of red and blue was greater
than that of green, the intensity of green was relative great in deep water because of absorbance peak of phytoplankton at red
and blue, and non-algal particle at blue and violet; radiance reflection of green was greater than that of blue and red. There was
an intensive reflection at the upper part of the water, it maybe due to greater concentration of phytoplankton.
