| 摘 要： | 对区域生态风险评价的主要内容进行了分析：包括区域界定、风险识别、受体分析、暴露评价与危害评价、风险表征等。与一般生态风险评价不同，区域生态风险评价考虑了区域的异质性特点。从区域生态风险评价的发展历程和意义、基本理论和方法等方面入手，结合典型案例，探讨了区域生态风险评价研究进展，并指出今后研究的方向，重点为开发与应用区域尺度的多风险源、多受体及错综复杂关系的生态风险评价模型。

| Abstract: | We summarize the main contents of RERA(regional ecological risk assessment),including region definition,risk identification,receptor analysis,exposure and damage assessment and risk characterization.Compared with general ecological risk assessment,RERA covers the spatial heterogeneity.From its development history,basic theory and method and in combination with typical cases,we discuss the research progress;point out the future research direction of RERA,mainly in establishing ecological assessment model wit... |
