| 摘 要： | 本文根据天然水体中溶解有机在碳与化学需氧量和生化需氧量之间的相关性，以及有机酸当量和水体溶解有机碳之间的近似定量关系，提出了由化学需氧量或生化需氧量得到溶解有机碳或总有机碳浓度，最终得到有机酸和有机酸根当量浓度的转换方法，为大区域天然水体有机酸碱缓冲作用的评估提供了一个实用的转换途径。

| Abstract: | According to the relations between BOD or COD and DOC and the similar quantity relations between DOC and organic acid equivalent concentration in natural water, a method for estimating organic acid equivalent concentration from conventional aquatic monitoring items is suggested in this paper. It is useful for estimating the geographic distribution of acidification capacity of natural water in a large regional scale. |
