摘要
区域生态风险评价是指在区域尺度上描述和评估区域的环境污染、人为活动或自然灾害对生态系统及其组分产生不利作用的可能性和大小的过程,其目的在于为区域风险管理提供理论和技术支持。该文探讨了一种基于景观结构的评价方法及步骤,并提出了该研究当前存在的问题。
Regional ecological risk assessment refers to the access of dicribing and evaluating the probability and level of artificial or natural damage to ecosystem and its component in regioncal scale,which purpose is to provide theoretical and technical support to regional risk management.In this paper,the method and procedure of regional ecological risk assessment were discussed,based on analyzing landscape structure.And then the existing problems of the research currently were offered.
