摘　　要：本研究基于土地利用、兴趣点、社会经济统计等数据,从乡镇尺度揭示了北京生态涵养区经济发展、农产品生产、社会保障、生态服务、旅游休闲以及综合功能的空间特征,并运用Spearman秩相关分析、生产可能性边界(PPF)、权衡强度指数等定量探讨了多功能间的权衡-协同关系及其权衡程度。结果表明:(1)经济发展、社会保障和休闲旅游功能的空间格局相似;生态服务功能与经济发展、社会保障和农产品生产功能的空间格局基本相逆。(2)经济发展与农产品生产/社会保障功能为显著协同关系;经济发展/农产品生产/社会保障与生态服务功能为显著权衡关系。(3)按照"‘权衡强度越小,功能间共生发展’‘权衡强度越大,最多发展一种功能’"的思路,以追求乡村功能组合的综合效益最大化为目标,将生态涵养区划分为I(4种功能共生)、II(3种功能共生)、III(2种功能共生)和IV(单一功能发展)4种类型区。研究结果将为区域乡村振兴规划编制提供参考,为乡村功能协同发展路径设计提供技术支撑。Based on land use, point of interest, socio-economic statistics and other data, this study constructs an evaluation system of rural function from five dimensions of economic development, agricultural product production, social security, ecological services and tourism and leisure, and reveals the spatial characteristics of the five functions above and their comprehensive functions of the ecological conservation area from the township scale. By means of Spearman rank correlation analysis, production possibility frontier(PPF) and tradeoff intensity index and so on, the trade-off coordination relationship and the degree of trade-off between rural functions are quantitatively discussed. The results show that:(1) the spatial patterns of economic development, social security and leisure tourism functions are similar;on the contrary, the functions of economic development, social security and agricultural products production in towns with strong ecological service function are often weak.(2) There is a significant synergy relationship between economic development and agricultural production/social security function, and a significant trade-off relationship between economic development/agricultural production/social security and ecological service function. And the trade-off intensity is economic development-ecological services > social security-ecological services >agricultural production-ecological services. When it comes to the PPF curve, we can conclude that the trade-off between economic development/agricultural product production and ecological service function is similar. That is to say, the trade-off between which will be weakened while sustainably developing the ecological services. The trade-off between social security and ecological services will intensify with the continuous investment of ecological services. The synergetic effect of economic development on agricultural production(social security) function will slow down with the development of economic function.(3) According to the idea of "the less the trade
