基于ArcGIS的高标准基本农田工程设计的探索与研究

Exploration and research on high-standard basic farmland engineering design based on ArcGIS

为克服高标准基本农田工程传统设计方法很难从三维直观反映项目区状况,以及在工程内容布设上繁琐、不智能等缺点,通过在设计方法中引入ArcGIS软件,以期探索和研究一种更直观更合理的工程设计方法。结合ArcGIS中DEM建模、土方计算、水文分析等方法,对项目区进行三维模型构建、地形分析、水文分析等,从而为高标准基本农田工程中涉及的主要三项工程的规划设计提供辅助决策,并且通过三维模型可以更直观反映整治前后项目区的变化。

To overcome the disadvantages of the traditional design method of high-standard basic farmland engineering,such as not intuitive in reflecting the area of project,tedious and unintelligent in designing,ArcGIS software was introduced into the design to explore and study a more intuitive and reasonable engineering design method.With DEM,earthwork calculation,hydrological analysis and other methods in ArcGIS,the 3 D visual model of the project area can be established and the landform and hydrologic data can be analyzed.It can provide auxiliary decision-making for the planning and design of the main three projects involved in high-standard basic farmland engineering.And the changes between before and after the renovation of the project area can be intuitively reflected on the three-dimensional model.
