Abstract

The oxygen regime of the channel flow of the small Maima River (Upper Ob basin) has been considered. A study of the spatial and seasonal variations of oxygen regime characteristics in the mouth part of the river and its tributaries has shown that they vary from their sources to the mouths. The effect of the industrial–residential agglomeration of Gorno-Altaisk on surface water quality in the region has been assessed. The oxygen regime was found to deteriorate from large to small rivers and their tributaries. An integral index of surface runoff by oxygen regime characteristics is proposed: high quality (low-pollution water)―less than 10 units, medium quality (polluted water)―10–30 units, and low quality (polluted water)―more than 30 units.

上鄂毕盆地小麦玛河河道水流氧气状况

摘要

已经考虑了Maima小河（Ob上游盆地）河道的氧气状态。对河流及其支流河口部分氧气状况特征的空间和季节变化的研究表明，它们的来源各不相同。评估了戈尔诺-阿尔泰斯克工业-居民区集聚对该地区地表水水质的影响。人们发现，从大河到小河及其支流，氧气状况都会恶化。提出了一种由氧气状态特征决定的地表径流的综合指数：高质量（低污染水）－少于10个单位；中等质量（污染水）－10－30个单位；劣质（污染水）－大于30个单位单位。
