摘　　要：以延边朝鲜族自治州为研究对象,结合当地具体地理及气候状况,将该区农业生态系统健康评价指标划分为恶化、不健康、一般、较健康、健康5级,建立了基于P-S-R概念模型的综合评价指标体系。结果表明,近11年,该地区农业生态系统除2002、2003年处于一般健康状态外,其他年份都处于较健康状态。在该区8个县市中,珲春市和敦化市的农业生态系统一直处于较健康状态,而延吉市和图们市农业生态系统的健康状态不容乐观。With Yanbian Korean Autonomous Prefecture as the study object,combining with local geography and climatic conditions,an evaluation index system was established based on P-S-R conceptual model. There were five levels( deterioration,unhealthy,generally healthy,sub-healthy and healthy) in this model. In recent 11 years,agro-ecosystem in Yanbian Korean Autonomous Prefecture was in generally healthy state in 2002 and 2003 but in sub-healthy state in other years. Agro-ecosystem in Hunchun City and Dunhua City was in sub-healthy state,while Yanji City and Tumen City were worse.
