摘要
以江苏沿江地区为例,采用相对风险模型(RRM),并引入风险源强度和生态效应强度指标,构建了渐进型风险源的生态风险评价系统,对其开发利用前后进行了比较,分析了生态风险值与空间分布规律。结果表明,该方法直观、简便,便于风险管理。
Taking areas near the Yangtze River in Jiangsu province for an example,the method of relative risk model（RRM） is applied to establish ecological risk assessment model with evolutionary risk sources by considering the strength index of risk sources and ecological effect.Comparison of the development and utilization before and after,the ecological risk value and spatial distribution rules are analyzed.The results show that the proposed method is perceptual intuition and simple,which is easy to risk management.
