摘要
本文总结了3年大伙房水库溶解氧研究的结果。实体调查表明:表层溶解氧一般不小于4.0mg/l,有随水温增加而降低的趋势。水体的热成层和溶氧分层,由于热排水在表层的扩散而提前和延长,导致湖下层氧的耗竭加强.冬季受热影响区不结冰,未出现逆温层.
This article summarizes scientific results in the studing the dissolvedoxygen in Dahuofang reservoir during april 1981 to april 1984.The results indicatethat the dissolved oxygen in the suface water layer is not below 4.0 mg/l,and thedissolved oxygen are decreased when the water temperature are increased.The the-rmal layer and the dissolved oxygen stratification in body of water formed inearlier on and prolongation as the thermal dicharge spreaded in the suface water.The results quickened exhaustion of oxygen in lower layer of lake.The inversionlayer in winter were not observed in the regions of increasing temperature.
