摘　　要：利用因子分析法和主成分分析法构建包括资源基础、生态环境、发展规模、社会科技和政府支持5个主成分共17个具体指标的县域尺度都市农业可持续发展评价指标体系,对北京市10个远郊区县2004 ～2011年都市农业可持续发展的时空变化特征进行评价和分析.研究发现：（1）2004 ～2011年北京市各区县县域都市农业可持续发展水平不断提高;资源基础条件不断提高;生态环境不断改善;产业规模不断扩大;社会科技投入略显不足;政府支持因子各区县变动差别较大,资金支持的持续性较差.（2）都市农业可持续发展综合评价指数和各主成分得分的空间分布格局与地形、距中心城区的距离有关.Using the factor and principal component analysis methods,a comprehensive indicator system containing 17 specific indicators classified as 5 principal components is built to evaluate the sustainable development statement of 80urban agriculture from the year 2004 to 2011 at the county level in Beijing.The 5 principal components are naturalresource base,eco-environment,industry development scale,social science and technology condition andgovernment support.The results show that：（1） from the year 2004 to 2011,the urban agriculture sustainabledevelopment level has gradually increased; the natural resource base conditions has been strengthened; the eco-environment has improved; the industry development scale has expanded; while the social science and technologyinvestment is slightly a lack and in terms of the government support factor,its annual variation is large and itspersistence is poor.（2） the spatial distribution characteristics of the comprehensive evaluation scores and the fivemain factors components scores are closely related to the terrain and the distance from the studied county to thecenter city.
