可视化河流水环境数学模型的设计与开发

Design and Development of the Visual River Water Environmental Mathematic Models

泰安市在河流水质信息管理方面仍处于传统水平,尚缺乏全面友好界面的系统研究。利用地理信息系统(Ma-pObjects)与一维水质模型的集成开发,可将河流概化,以颜色深浅表示污染物的浓度变化,使模拟结果可视化显示,实现空间数据与属性数据的查询、统计和分析功能,从而建立人机交互式河流水质信息管理系统。依据GIS的可视化功能了解排污地点与污染状况发展的时空联系,以达到"预防为主,防治结合"的目的,为泰安市高效、准确地完成"十二五"规划中对中小型河流全面治理的目标提供了有效手段。

The research on river water quality information management in Tai＇an City is still in traditional level and lacks systematic study on the comprehensive and friendly interface.The rivers were generalized by the integrated development of GIS and one-dimensional water quality model.The depth of river color stands for the concentration of pollutants.The results indicate that the design can implement the visualization of simulation results,the query,statistics and analysis of spatial data and attribute data,establish human-oriented and interactive mode.Based on the visualization function of GIS,learned the links of time and space between sewage pollution location and pollution development and achieved the purpose of prevention first,combining prevention with control,it provides an effective means to complete the 12th Five-Year Plan for a comprehensive treatment of the small and medium rivers.
