摘　　要：在综合分析北京市通州区与河北香河县、大厂县接壤区农用地分等成果及其产能的基础上,建立了城郊农用地健康评价等别与产能PI1、农产品质量PI2、土壤质量PI3、地表水与地下水水质PI4、投入产出状况PI55类指标体系和内梅罗(N L Nemerou)指数评价方法。研究结果表明,研究区农用地产能高、健康状态良好,但区域地表水水质差以及污水灌溉会使区域农用地面临一定的健康风险,提出保障城郊农用地健康的措施。Agriculture land health is an important research direction of the environmental and land resource management science, the domestic and foreign scholars have conducted the research on the soil and land health by the pollutant diagnostic and analysis in region ecosystem. In this article, based on agricultural land classification production and productivity of the border between Tongzhou district in Beijing city, Xianghe county and Dachang county in Hebei province, the appraise index system and the N L Nemerou exponential appraise method are discussed. The index system includes five genus： productivity （PI1）, farm produce quality （PI2）, soil quality （PI3）, water quality of surface water and underground water （PI4）, status of input and output （PI5）. The result indicates that the agricultural land productivity is high and health status is better in the research area, the bad water quality of surface water and irrational sewage irrigation could make some risk to agriculture land health in the area. Some measures for keeping agriculture land health in suburb are put forward in the end.
