| 摘 要： | 为了模拟洪水灾害发生、发展过程,制定科学的抢险方案,从而减少洪水灾害造成的损失。作者基于地理信息系统技术,在ArcGIS9.1平台上,首先建立了不规则三角网(TIN)模型,其次基于计算机图形学的种子蔓延算法,用VC.net语言开发了一个控件,实现了洪水淹没区范围确定,最后把它应用于鄱阳湖地区防汛抗洪地理信息中,取得了良好的效果。

| Abstract: | In order to simulate flood phenomenon and decrease the loss of disaster,based on ArcGIS9.1,the authors have firstly established the irregular triangular net(TIN) model.Then on the basis of computer graphics seed spread algorithm,and with VC.net as programming language,they have developed a control to determine the flood submergence area scope.Finally they use this control in the Geographic Information System of Flood Prevention and Control in Poyang Lake Area and obtain an ideal result. |
