藻类光合特性的生态学意义早已被认识。然而，不可能简单地将这些应用于自然种群的行为，因为后者通常受在自然沃茨的光强度特征的强垂直梯度内连续循环的细胞的平均行为的支配。在这种情况下，具有生态意义的单位通常可以解释为单位面积地表下的总人口。这个单位的光合作用构成了有关水柱中的总的或整体的光合作用。它的特性具有直接的生态意义。本文讨论了它们与藻类光合特性的关系，并考虑了各种环境因素的影响。本文首先结合淡水浮游硅藻Asterionella福尔摩沙Hass光合作用的实验研究，分析了水体中光合速率随深度的变化。试图建立一个数学模型（塔林在1955年对该模型作了初步说明），描述水柱中整体光合作用的一般情况。它的应用生态情况说明了有关的例子，在温德米尔湖的Asterionella的增长。
The ecological significance of the photosynthetic characteristics of planktonic algae has long been recognized. A simple application of these to the behaviour of natural populations is not possible, however, since the latter is normally governed by the average behaviour of cells continuously circulating within the strong vertical gradient of light intensity characteristic of natural waters. In this situation the unit of ecological significance can often be interpreted as the total population present below unit area of surface. The photosynthesis of this unit constitutes the total or integral photosynthesis in the water column concerned. Its properties are of direct ecological interest. Their relation to the photosynthetic characteristics of the algae present is discussed in this paper, and the influence of various environmental factors is considered. Here an analysis of the variation of photosynthetic rate with depth in the water column is first discussed in relation to an experimental study of the photosynthesis of a freshwater plankton diatom, Asterionella formosa Hass. A mathematical model (of which a preliminary account was given by Talling, 1955), describing the general case of integral photosynthesis in the water column, is attempted. Its application to ecological situations is illustrated by examples relating to the growth of Asterionella in Lake Windermere.
