GIS技术在国内环境风险评价中的应用研究

Application of GIS Technology in Domestic Environment Risk Assessment

环境风险评价是随着中国一系列环境污染事故频发和相应技术导则的出台而慢慢发展起来的一个新兴领域,学者结合GIS技术围绕环境风险评价也展开了多领域研究。论文综述了地理信息系统(GIS)技术在广义上的灾害风险、生态风险和狭义上的环境风险评价中的研究进展和应用现状。GIS技术支持下的灾害类和生态环境风险评价应用较多,但是与狭义上的环境风险评价结合较少,主要是应用GIS的空间分析功能进行综合分析。以后利用GIS强大的空间分析和数据处理的优势,与环境风险评价模型的关联和集成是研究的重点方向。

Environmental risk assessment is a new field,it is slowly developed along with the series of environmental pollution accidents and the corresponding technical guidelines. Combined with GIS technology,the scholars has launched researches on environmental risk assessment. This paper introduced related concepts and environmental risk assessment of research contents,research progress and application status of geographic information system( GIS) technology in the broad sense of disaster risk,ecological risk and the narrow sense of the environmental risk assessment. On the basis of the space analysis and data processing capabilities of GIS,its relation and combination with environmental risk assessment model were discussed.
