Therefore, it will help to resolve the water pollution discordance. On the basis of assessing economic loss due to water pollution, this paper employed water environment model to describe the spatial impact of pollutant discharge in rivers. In consideration of the environmental and economic effects of pollutant discharge, a theoretical model for water pollution compensation in rivers was proposed, with its basic characteristics, processing methods and application conditions discussed in the paper.

在水污染经济损失评估的基础上，以河流为研究对象，采用水环境数学模型的方法描述了污染物排放的空间影响关系，进而把超量排放的环境影响与经济影响联系起来，对模型的基本特征、处理方法和应用范围进行了讨论，并且以太湖流域范围内的京杭运河为例进行实证研究，得到了河流水污染损失补偿的数学模型。

本文首先通过不同淋水高度、淋水密度、过塔风速等的逆流及横流试验塔的热水试验，求出相应条件下的淋水水滴当量直径，再在工业塔的条件下，利用水滴散热公式，计算出雨区散热效果，化为无因次数-冷却数，作出图及计算公式。

To control the ground-water table on irrigated lands is vitally important in arid and semi-arid regions. In order to determine the standard of water table control, considerable attentions were paid to the "critical depth"(or "safe depth") of ground-water table. The salts accumulate in the top soil if the water table is not deeper than this depth. The conditions that the salts accumulate in any layer of the soil owing to the movement of soil moisture are:(1) the supplement of soil moisture from neighboring...
