高邮市城区污染强度与北澄子河环境容量的相关性

根据2004年度高邮市主要纳污河流北澄子河流经城区后，污染物增加量、城区段河流的自净量及河流剩余环境容量，计算出城区段河流的总环境容量，再通过各年度河流流经城区后污染物增加量及自净量，计算出各年度城区段河流的剩余环境容量，分析城区污染强度与北澄子河环境容量的相关性，得到线性公式，从而可以根据城区污染强度推算环境容量的变化，或根据环境容量的变化推算城区污染强度。

Interrelation Between Urban Pollution Intensity and Environmental Capacity of Beichengzi River in Gaoyou City

This paper calculates the total environmental capacity of the urban rivers according to the pollutant increasing amount of Beichengzi river, when it flows by the urban as a primary river to accommodate contaminant, selfpurification amount in the urban rivers and the surplus pollution intensity in 2004, then calculates the annual surplus pollution intensity of the urban rivers from pollutant increasing amount and selfpufification amount, analyzes the interrelation between the urban pollution intensity and the environmental capacity of the Beichengzi fiver, gives the linear formula to calculate the change of environmental quality from the urban pollution capacity or the urban pollution capacity from the change of environmental quality.
