摘　　要：选取对数据需求量相对较小的河流一维稳态水质模型QUAL2K模型开展水质模型模拟与水质风险评估的研究。为了简化QUAL2K模型建模过程,提高模型计算效率,优化模拟结果展示效果以及实现水质风险评价的应用,将QUAL2K模型进行B/S架构系统集成,运用ArcGIS平台实现水质模型结果的可视化动态播放和专题图制作,并提出通过各时间步长的水质模拟结果统计各河段的水质超标风险概率的水质风险评价方法,为流域水环境优化管理提供决策依据。With the increasingly prominent water environment pollution problem,the demand of water quality risk assessment is rapidly increasing as well.In this article,we chose the one-dimensional steady state water quality model-QUAL2 K model,which has small data demand and is broadly applied to river network model,to simulate the water quality and evaluate the water quality risk.In order to simplify the model development process,improve the calculation efficiency,optimize display effects of model results,and achieve the application in water quality risk assessment,we transformed the QUAL2 K model into B/S architecture system integration,utilized ArcGIS platform to achieve the visually dynamic display of water quality simulation results and thematic map production,and then proposed the water quality risk assessment method from the water quality risk probability based on time step water quality simulation results.The method can provide the decision-making basis for the water environment management.
