基于多源数据的海水水质空间评价系统设计

传统海水水质评价的数据来源单一,其评价结果不具对比性.本文将多源监测数据(浮标、走航和遥感数据等)引入海水水质评价中,利用多源监测数据增加评价结果在空间和时间尺度上的对比性,并结合GIS技术建立基于ArcGIS Engine、SQL Server数据库和Visual C#的海水水质空间评价系统,以实现多源监测数据的输入与管理、水质环境信息的选择与查询、海水水质空间评价以及综合评价结果制图输出与发布的功能,同时实现海水水质评价结果的直观、可视化表达.实践表明多源监测数据应用于海水水质空间评价系统是可行的,并为控制环境污染、进行浴场和度假区的规划提供了科学依据.

Design of the seawater quality spatial evaluation system based on multi-source data

Data sources of most traditional seawater quality evaluation are very single, so the evaluation results are non-comparative, but this paper will introduce multi-source monitoring data (buoy data, underway data and remote sensing data, etc.) into seawater quality evaluation. Use of multi-source monitoring data can increase the relative property of evaluation results in space and time scales,based on ArcGIS Engine, SQL Server database and Visual C# programming language and combined with GIS technology to build the seawater quality spatial evaluation system. The system will achieve multi-source monitoring data input and management, selection and inquiry of seawater environmental information, seawater quality spatial evaluation and cartographic output publishing of the comprehensive evaluation results, while it will also achieve the intuitive and visual expression of the seawater quality evaluation. Practice shows that the multi-source monitoring data used to the seawater quality spatial evaluation system is entirely feasible, and also provide a scientific basis for the control of environmental pollution, bathing placeand holiday resort planning.
