基于 GIS 的内蒙古水源地环境安全管理信息系统

摘要

The Inner Mongolia Autonomous Region is facing the dual threat of drought,semi arid and regional water source environmental safety for a long time.Moreover,the technology for environmental safety management is seriously outdated.In this paper,we have established the basic database of the surface morphology,hydrology,water quality,pollution sources, fracture surface and spatial water source environmental information in the Inner Mongolia Autonomous Region.In consideration of the strong spatial characteristics of the water source environmental information,the Inner Mongolia Autonomous Region water environmental safety management information system is developed on the ArcGIS network platform with C++ language and B/S architecturein this paper.The system not only achieves the visual computer management of the spatial information of water source but also provides guidance for the division of water source and water source protection management combining with water source and environmental monitoring,pollution sources and other data for the environmental safety analysis.Using the developed method in some cities of Inner Mongolia,the system shows strong practicability,information display intuitive and good universality,which provides effective decision support for environmental safety,high efficiency management and early warning of the water source in the autonomous region.%内蒙古自治区境内长期面临干旱、半干旱和区域水源地环境安全的双重威胁，且存在环境安全管理技术手段严重落后的问题。建立了内蒙古自治区包括地表形态、水文、水质、污染源、断面等属性和空间水源环境信息的基础数据库。鉴于水源地环境信息具有极强的空间特征，利用 C++语言、B/S 架构，在 ArcGIS 网络平台上开发构建了内蒙古自治区水源地环境安全管理信息系统，实现了水源地空间信息大数据的可视化计算机管理，结合水源地与环境监察、污染源等数据进行环境安全分析，为水源地的划分和水源保护区的管理提供指导性支持。系统在内蒙古部分盟市投入使用后的结果表明，系统实用性强，信息显示直观，具有较好的普适性，为自治区水源地环境安全、高效管理和预警提供有效的决策支持。
