| 摘 要： | 生态风险评价已进入到区域生态风险评价阶段,评价尺度的扩展反映了人类对自身生命支持系统的关注和对环境进行管理和决策的实践需要。针对区域尺度的生态风险评价,着重从评价区域类型、评价内容、范式、方法、技术、模型等层面进行综述。结果表明:区域生态风险评估的核心和关键是合理选择和表征区域生态风险源和风险受体,科学探讨和量化多风险源和多风险受体的交互作用。面向未来,区域生态风险评价应该在等级斑块动态理论框架指导下,发展一套具体的评价方法,深入进行不确定性分析,加强G IS技术和其他模型、技术的综合运用。

| Abstract: | Ecological Risk Assessment(ERA) is evolving.With the expansion of scale,it goes into the phase of Regional Risk Ecological Risk(RERA),which reflects the practice requirement of environment management and decision-making.Facing multi-stressors,multi-stressors and their complex interaction at regional scale,different methods,techniques and models are applied in many RERA case studies in the past 20 years.Although paradigm,framework and achievements are reached,there still have many problems in RERA,such as th... |
