【摘要】 地理信息系统已经成为研究环境地球化学问题的重要手段。基于ArcEngine地理信息系统平台,使用VC++可视化编程工具建立了黄石市地表水环境地球化学信息系统,该系统具有信息管理、信息查询、统计分析和水质评价等功能。重点探讨了建立系统的技术方案以及系统框架建立和水质评价模型的关键技术。利用该系统对黄石市地表水环境质量进行评价,表明该系统的建立有助于科学管理地表水环境地球化学信息,同时利用评价模型得出的评价结果也为解决环境问题提供了依据。更多还原

【Abstract】 GIS is the important means to study the environmental geochemistry question. Based on ArcEngine GIS platform and VC++ visual programming tool,the environmental geochemistry information system about the surface water in Huangshi City was established. The system had the functions of the information management,information query,statistic analysis and the water quality assessment. The technology scheme of establishing the system and the key technologies of establishing the system frame and the water quality evaluation model were mainly discussed. Using this system,the environmental quality of surface water in Huangshi City was evaluated. The results showed that the establishment of the system was helpful for the scientific management of environmental geochemistry information of surface water. And the evaluation results obtained by using the evaluation model also provided basis for solving the environmental question.更多还原
