ArcGIS在银北灌区暗管排水工程中的应用

The Application of ArcGIS for Subsurface Pipe Drainage Project in the North Irrigation District of Yinchuan

灌区暗管排水工程规划设计需要兼顾项目区地形、地貌和既有灌排系统的布局,顺势而为,兴利除害。针对宁夏银北灌区暗管排水工程规划设计与工程管理中存在的问题,尝试将ArcGIS软件与SQL Server数据库管理相结合,应用于暗管排水工程规划设计及其工程信息管理与查询。以暗管排水项目区实地调研资料为依据,重点介绍如何通过软件分析,获取暗管排水项目区地形、坡度、坡向和地形剖面等空间地理信息;建立了银北灌区暗管排水工程可视化管理平台,形成暗管排水数据库资料,以期为暗管排水工程规划设计及工程信息化管理提供参考。

The planning and design of pipe drainage project in irrigation area should take into account the topography, land feature and existing irrigation system. Targeted at the problems from the planning, design and management of pipe drainage project in the north Irrigation district of Yinchuan, Ningxia, this paper attempts to conduct the design of pipe drain engineering, management and inquiry of the project by using the technique of combining ArcGIS software and SQL database. Based on the investigation data, the method operating the software to obtain the spatial geographic information are introduced in the project area, such as terrain, slope, slope direction and so on. The management platform and database of underground drainage project are established to provide a reference for the planning and design of the pipe drainage construction and the information management of the project.
