随着京津冀协同发展上升为国家战略,如何实现其区域内城市农业多中心互动,成为其综合竞争力提升和协同效应发挥的重要推动因子.借鉴共生理论,从能级、对外关联和外向功能3个视角进行分析,确定了京津冀城市群城市农业多中心共生关系.结果表明:河北省11地市在农业能级、农业对外关联、农业外向功能强度等方面表现出优势,而京、津两市则表现为劣势;京津冀城市群城市农业总能级排名方面,保定、石家庄、邯郸、沧州、邢台分列第1～5位,天津列第8,而北京列末位;城市农业对外关联方面,邯郸、邢台、石家庄分居第1～3位,天津、北京分列第6、第7位;外向功能强度方面,河北省11地市全部表现为外向功能,其中承德、张家口、秦皇岛分列第1～3位,而天津、北京则均小于1,表现为内向功能;综合考虑各市行政地位、整体实力和区位,建议把北京、天津和石家庄列为一级农业中心城市,把邯郸、邢台、衡水、保定列为二级农业中心城市.最后,从制定京津冀城市农群业发展规划、构建共生体制、实现包容性共生发展、形成创新型集群等方面提出协同发展对策.

With Beijing-Tianjin-Hebei metropolitan's coordinated development into national strategies, how to realize its urban agriculture's polycentric interaction becomes an important factor for its future integration competitiveness and sustainable cooperation development. Based on the above considerations and the polycentric symbiosis theory, Beijing-Tianjin-Hebei Metropolitan's urban agriculture symbiotic relationship is analyzed and determined from three directions such as urban agriculture capacity level, urban agriculture outward correlation and urban agriculture outward function. The results show that 11 cities in Hebei Province has advantages in terms of agricultural energy level, agricultural external correlation, agricultural extroversion function intensity, while Beijing and Tianjin city show inferior position in terms of agricultural energy level, agricultural external correlation, agricultural extroversion function intensity and so on. In terms of the total agricultural energy levels of cities in Beijing-Tianjin-Hebei metropolitan, Baoding, Shijiazhuang, Handan, Cangzhou and Xingtai ranks the first to the fifth respectively, Tianjin ranks the eighth, and Beijing ranks the last. In terms of external relation of urban agriculture, Handan, Xingtai and Shijiazhuang ranks the first to the third respectively, Tianjin and Beijing ranks the sixth and the seventh respectively.In terms of intensity of external relation urban agriculture, 11 cities in Hebei Province show extroverted function, in which Chengde, Zhangjiakou and Qinhuangdao ranks the first to the third respectively, while Tianjin and Beijing are all less than 1, showing introverted function. Considering the administrative status, overall strength and location of each city, it is suggested that Beijing, Tianjin and Shijiazhuang should be classified as first-class agricultural centers and Handan, Xingtai, Hengshui and Baoding as second-class agricultural centers. Finally, on the basis of the above analysis, some countermeasures of polycentric symbiosis are proposed from the establishment of Beijing-Tianjin-Hebei metropolitan urban agriculture development plan, construction of symbiotic systems, polycentric cluster, inclusive symbiosis development, infrastructure support, innovative clusters development, integration and development of related industries and other aspects of collaborative development of Beijing-Tianjin-Hebei metropolitan's urban agriculture.
