【摘要】 GIS与二维水流泥沙数学模型集成的研究是一项比较崭新的课题。由于众多因素的存在,我国河流数学模型目前的状况还不尽如人意。3S技术的出现带动了许多学科的飞速发展,针对目前水流泥沙数学模型的发展现状,本文探讨了GIS与二维水流泥沙数学模型集成的重要意义,对GIS与二维水流泥沙数学模型集成可能存在的问题提出了解决的一般方法与步骤、给出了集成的各种模式,以当前流行的GIS产品ArcView结合工程实例说明GIS与二维水流泥沙数学模型集成的原理与方法,并探讨了GIS与二维水流泥沙数学模型可视化集成的研究意义及可视化相关技术问题,最后以自主开发的软件MdGIS作为实例说明。本文探讨的GIS与二维泥沙数学模型的集成方法与可视化研究不仅对泥沙淤积分析研究及江河泥沙灾害的防治具有现实意义,而且对研究泥沙数学模型的发展有一定的参考价值。更多还原

【Abstract】 It is a rather new subject to study on the integration of GIS and 2Dwater-sediment numerical model at the present time. However, due to many factors’existence, the development of water-sediment numerical model in our country is notso sound。With the 3S technology appearances, many science fields have gained arather large development。Aiming at the status quo of water-sediment numerical model, this paperdiscusses their integration significance, brings out the solving-way with possibleintegration problem, and puts forward several kinds of integration modes. It takescurrent popular GIS production----ArcView as example, and associates with the actualproject, to illustrate the integration principle and method. This paper also discussesthe integration meaning and correlation problems of GIS and 2D water-sedimentnumerical model visual display. At last, this paper takes self-designed soft---MdGISas instance to illustrate the problems mentioned above.GIS and 2D water-sediment numerical model integration method and visualdisplay not only has actual meaning to sediment silting analysis and river disasterprevention, but also has some value to the water-sediment numerical modeldevelopment更多还原
