摘　　要：利用温度扩散数学模型研究了印度尼西亚某内陆河流域拟建电厂冷却水在河中的温度扩散规律及影响范围,结果表明:①河道天然流量较大时,电厂冷却水在天然河道中主要沿河道纵向扩散,等温线与河道趋于平行;②河道流量较小时,电厂冷却水趋于横向扩散,并向上游蔓延;③在各种流量下,取水口断面处水温稳定,未产生温升现象;④从温排水角度分析,排水口的位置、形式对取水没有产生影响。This article used temperature diffusion mathematical model to study the diffusion regularity and effected range of the cooling water,which was discharged from a power plant planned to build in an inland river basin of Indonesia.The results show that： when the river natural runoff is bigger,the cooling water diffuses longitudinally along the river and the isothermals are almost parallel with the river;when the river runoff reduces,the cooling water diffuses horizontally and spreads to upstream;whether the runoff is big or small,the temperature around the water inlet is stability;analyze from the perspective of the direct discharging type cooling water river,the position and form of the drain have no effect on water intaking.
