摘　　要：采用GLLVHT模型对江苏LNG项目冷海水排放温度场进行模拟计算,预测其环境影响。并针对南通海域的具体情况采用不同计算方案进行计算,根据结果分析可知影响程度最大的方案是:温降大于0.5℃的面积最大约为0.93 km2;影响程度最小的方案:温降大于0.5℃的面积最大约为0.89 km2。根据计算结果,同时考虑到技术、经济因素,在保证安全情况下推荐采用排口1处表面排放。GLLVHT model was applied to the simulation of temperature distribution of cooled water discharge of Jiangsu LNG project for the prediction of environmental influences. Based on the discussion of different discharge conditions in Nantong coastal area, we know that, the regions where temperature drop is more than 0.5℃ is about 0.93km^2 in the scheme with maximal impact on the water environment and 0.89km^2 in the scheme with minimum impact. Taking the technical and economic factors into consideration, we put forward our proposals that the surface discharge may be located at the receiving station.
