摘　　要：以可持续发展理论为指导,依据2006年全球变化人类行为计划(IHDP)第六届开放会议精神,参考前人有关生态环境评价框架和指标组合研究,建立了适合北方农牧交错地带特点的区域适应能力评价模型(PSR-RAD),并对模型的构建思想、参数意义和评价指标的具体计算进行了探讨,以期为全球变化区域响应研究提供参考。针对北方农牧交错地带的实际情况,PSRRAD模型将第四纪地质地貌与现代生态环境研究整合,提出第四纪地质脆弱指数概念,在生态环境胁迫分析中,提出衡量农牧交错地带农牧业环境胁迫程度的地农牧业生产量指数的概念,使生态环境先天与后天胁迫因子、自然与人文因子得以客观体现,对生态环境脆弱性研究的时间和空间尺度均有所拓展。According to the guideline adopted by IHDP＇s Sixth Open Meeting in 2006,based on sustainable development theory and the formers＇ achievement in index and framework of environmental ecological evaluation,regional adaptability model ＂PSRRAD＂ was built in order to provide reference for regional response to global change.The model was adequate for farming-pastoral zone in the northern of China.The building idea of the model was discussed,parameter was explained,and calculation of evaluation index was introduced.For farming-pastoral zone in the northern of China,the model ＂PSRRAD＂ firstly puts forward the concept of quaternary geology vulnerability index after integrating quaternary geology and modern ecological environment research;and firstly shows the concept of farming-pastoral production per unit which could measure the environmental stress of farming-grazing production in farming-pastoral zone.The congenital（or acquired） and natural（or humanistic） factors could be embodied objectively.Ecological environment vulnerability could be developed in time and space dimensions.
