【摘要】 现阶段我国多数城市面临着结构性、布局性环境风险凸显的问题,导致行政区域突发环境事件发生频次高、影响范围广。以珠海市为例,基于地市级行政区域环境风险系统研究,构建评估指标体系,利用GIS技术确定基于空间地理网格的评估单元,在此基础上提出风险等级划分模型,对评估单元进行风险量化分级,并通过行政区域风险等级分区,掌握全域环境风险分级特征。更多还原

【Abstract】 Most cities in China are confronted with strong environmental risks due to the issues related to their layout and industrial structures which lead to highly frequent environmental accidents in administrative regions with broad impacts. Taking Zhuhai city as an example, environmental risk analysis system research and environmental events based on the mechanism, set up the evaluation index system of municipal administrative regional environmental risk assessment, determining unit space based on the geographic grid using GIS technology, risk classification, risk characterization technology, proposed the risk classification model, application of regional environmental risk assessment methods can be divided into from high to low level of risk.更多还原
