Use of hydrooptical characteristics in monitoring the reservoir ecosystem is investigated. Two basic characteristics which are most commonly used for purposes of ecological monitoring having regard to information content and ease of measurements are considered: the beam attenuation coefficient ε, the and Secchi disc depth ZSD. Theoretical analysis shows a relationship of ε and ZSD with content of suspended matter and chlorophyll in water. It is concluded, however, that correct theoretical calculations of the content of these substances is not possible to correctly calculate these substances in a theoretical way from e and ZSD. In this context, empirical relationships of suspended matter and chlorophyll concentrations with hydrooptical characteristics are used for monitoring purposes. These relationships are regional in character, which is accounted for by the regional composition of suspended matter and by the intracellular concentration of pigments in algae. Examples of empirical relationships of suspended matter and chlorophyll concentrations with the beam attenuation coefficient and the Secchi depth in Lake Baikal, the Black Bea and the tropical waters of the Atlantic waters are given. It is found that in addition to the content of suspended matter and chlorophyll in reservoirs, it is important, for biological purposes, to know the thickness of the euphotic layer for total quantum irradiation Heuph.quant. Examples of the determination of the euphotic layer thickness for total quantum irradiation Heuph.quant. using Secchi depth for different reservoirs are provided.

水光特性在水库生态系统状态监测中的应用

研究了水光特性在水库生态系统监测中的应用。考虑到信息内容和测量的方便性，最常用于生态监测目的的两个基本特征：波束衰减系数 ε、和 Secchi 圆盘深度 ZSD。理论分析表明ε和ZSD与水中悬浮物和叶绿素含量的关系。然而，得出的结论是，这些物质的含量的正确理论计算是不可能从 e 和 ZSD 以理论方式正确计算这些物质的。在这方面，悬浮物和叶绿素浓度与水光特性的经验关系用于监测目的。这些关系具有地域性，这是由悬浮物的区域组成和藻类中色素的细胞内浓度引起的。给出了悬浮物和叶绿素浓度与贝加尔湖、黑贝亚和大西洋水域热带水域的光束衰减系数和塞奇深度的经验关系的例子。发现除了水库中悬浮物和叶绿素的含量外，就生物学目的而言，了解全量子辐照 Heuph.quant 的透光层厚度也很重要。确定总量子辐射的透光层厚度的示例 Heuph.quant。提供了对不同储层使用 Secchi 深度的方法。
