According to the characteristics of ecological conservation area, the evaluation index system is constructed from the system of ecological product supply and economic development, and the comprehensive evaluation method is used to evaluate the ecological product supply and economic development. Then the coupling coordination degree model is used to evaluate the coupling coordination degree of ecological product supply and economic development in 2019 in Beijing ecological conservation area and determine its coupling coordination type. The results show that in 2019, there is a large gap between ecological products and economic development of villages and towns in Beijing ecological conservation area. the high value and higher value of the supply capacity of ecological products are mainly distributed in Huairou District, Miyun District and Yanqing District. The areas with high level of economic development are mainly distributed in cities and towns in various districts and towns near the suburbs of Beijing. The coupling degree between ecological product supply and economic development of villages and towns in Beijing ecological conservation area is between 0.648 and 0.999, and the system is mainly in a high level coupling stage. The coupling coordination value is between 0.312 and 0.600, the internal difference of the coupling coordination degree is large, the overall coupling coordination level is not high, showing a weak mutual promotion relationship. The supply of ecological products and economic development of the villages and towns in the ecological conservation area of Beijing have not achieved synchronous development, and the villages and towns with lagging supply of ecological products and lagging economic development basically account for half of each other. The ecological conservation area of Beijing should be based on different resource advantages and adopt different strategies according to the supply of ecological products and economic development, so as to realize the complementarity and mutual promotion. 

结合生态涵养区的特点, 构建生态产品供给与经济发展两个系统评价指标体系, 采用综合评价法评估生态产品供给和经济发展状况, 采用耦合协调度模型分析北京市生态涵养区2019年生态产品供给与经济发展的耦合协调度及其耦合协调类型。结果表明, 2019年北京市生态涵养区各乡镇生态产品供给和经济发展差距较大, 生态产品供给能力的高值和较高值区域主要分布在怀柔区、密云区和延庆区, 经济发展水平较高的区域主要分布在各区的城镇以及靠近北京市近郊的乡镇。北京市生态涵养区各乡镇生态产品供给与经济发展的耦合度介于0.648~0.999之间, 处于高水平耦合阶段。耦合协调度值介于0.312~0.600之间, 耦合协调度内部差异较大, 整体耦合协调水平不高, 呈现较弱的耦合协调关系。北京市生态涵养区各乡镇生态产品供给与经济没有实现同步发展, 生态产品供给滞后型和经济发展滞后型的乡镇大约各占一半。建议北京生态涵养区应立足于不同的资源优势, 根据生态产品供给和经济发展状况采取不同的策略, 实现两者的互补和相互促进。
