环境监测信息空间表征技术研究与应用

随着环境问题的日益凸显及公众对环境问题的日益关注,如何将污染分布及发生规律、环境质量状况及变化趋势以科学、准确、直观的方式进行展示并以浅显易懂的方式传递给广大公众,是摆在环境管理者面前的一个问题.本文提出了环境监测信息空间表征定义,并介绍了基于GIS、大数据技术的环境监测信息空间表征的主要形式,包括:①点数据的空间表征;②线数据的空间表征;③面数据的空间表征;④三维可视化空间表征;⑤随时间变化的空间信息表征,以及各空间表征方法在环境监测中的应用.

Research and Application of Spatial Representation of Environmental Monitoring Information

Nowadays, the environmental problem has become increasingly prominent and the public pay more attention to environmen-tal problems. It has been a problem in front of the environmental management that how we can show the pollution distribution and oc-currence law, environmental quality status and trend of scientific, accurate and transfer these to the general public. In this paper, en-vironmental monitoring information of spatial representation of the definition is proposed. This paper introduces the main forms of envi-ronmental monitoring information spatial representation based on GIS and Big Data technology, including:①the spatial representation of point data;②the spatial characterization of line data;③data representations of region data;④3D visual spatial representations;⑤with spatial information representation of temporal variation, and the characterization methods of application effect.
