摘    要:在模拟昆承湖水流流场的基础上,模拟化学需氧量(CODMn)在湖水中的扩散情况;同时,利用昆承湖实测资料和水质的浓度场计算结果,得到其枯季环境容量.可以看出,昆承湖的流速较小,且方向由西北流向东南,可能是受长江径流和湖底西北高东南低的地形特征影响;从昆承湖的CODMn浓度实测值和计算值中,可以看出小于其水环境质量标准限值.这将进一步为实现常熟市湖泊水环境质量的不断提高、生态状况的持续改善与科学管理提供依据.

关 键 词:流场  化学需氧量  浓度场  扩散  环境容量

Abstract:Based on the calculating results of the flow field of the Kuncheng Lake the diffusion of the chemical oxygen demand(CODMn)in the lake is simulated.And by utilizing the observed data and the calculating results of the water quality concentration field of the lake the water environmental capacity in the dry season is achieved.From the results,it is shown that the velocity of the lake is small and the direction is from the northwest to the southeast as the topographic form is the northwest higher than the sout...
Keywords:flow field  chemical oxygen demand  concentration field  diffusion  environmental capacity
