基于ArcGIS Engine的地下水数值模拟平面三角网格自动剖分系统设计与实现研究

为有效地模拟地下水水流和溶质运移,快速、准确评价地下水资源,针对地下水数值模拟中空间离散与平面三角网格自动剖分问题,提出了一种基于ArcGIS Engine的平面三角网格自动剖分方法,并利用当前流行的.NET框架和C#语言设计实现了地下水数值模拟三角剖分系统。系统不仅能自动输出剖分所得三角形顶点与位置信息,同时可以进行手动校正与局部加密,最后结合实例对模拟区做了剖分分析,结果能较好地满足地下水数值模拟的要求。

The Triangular Grid Automeshening System Design and Implementation in Numerical Simulation of Groundwater Based on ArcGIS Engine

In order to simulate the groundwater flow and solute transport, rapid, accurate assessment of groundwater resources, an algorithm for space discretization and the triangular mesh automeshening in groundwater numerical simulation was presented based on ArcGIS Engine. C# language and. NET framework were used to design and finish the triangular mesh automeshening system in groundwater numerical simulation. The system not only can automatically output the triangle vertex and location information, at the same time can be manually corrected and re- fined locally. The simulation area was analyzed with examples, the results can better meet the requirements of the numerical simulation of groundwater.
