为了揭示农村发展与生态系统服务之间的关系，并帮助平衡这些因素，我们使用耦合模型对中国福建省2000 - 2015年农村发展与生态系统服务之间的关系进行了研究。首先，我们通过计算相对农村化指数（IRR）来表征全省各县的农村发展程度，并将各县划分为农村发展类型。其次，我们计算了三个生态系统服务（ES）的价值，并将它们重叠，得到每个县的ES总和。第三，计算了研究区的耦合度和耦合协调度，并分析了IRR与ES的相关性。结果表明，在研究期内，内部收益率均值呈下降趋势，与经济效益呈正相关，且相关程度逐年增加。剔除商务服务型县域后，耦合度处于对抗阶段，但趋于磨合阶段，耦合协调度处于高度协调阶段。虽然总体耦合协调度较高，但逐年下降，说明农村发展与生态系统服务的协调性越来越差。本文支持和验证了该地区农村发展项目的部分成果，为中国农村协调发展和生态系统服务保护提供了理论和决策支持，并为其他国家的类似研究提供了区域案例研究。
To reveal the relationship between rural development and ecosystem services and to assist in efforts to balance these factors, we used a coupling model to carry out a study of the relationship between rural development and ecosystem services in Fujian Province of China during the years 2000 to 2015. First, we characterized the degree of rural development for each county in the province by calculating its index of relative rurality (IRR) and classified the counties into rural development types. Second, we calculated the values of three ecosystem services (ES) and overlapped them to get the sum of ES for each county. Third, we calculated the coupling and coupling coordination degree and analyzed the correlation between IRR and ES in the study area. The results showed that the mean value of IRR declined over the study period, was positively correlated with ES, and the correlation degree increased year by year. Meanwhile the degree of coupling was in the antagonistic stage, but tended to run in stage with a highly coordinated stage coupling coordination degree, if the business services type-counties were excluded. Although the overall coupling coordination degree was high, it declined yearly, which meant that rural development and ecosystem services increasingly lacked coordination. This paper supports and verifies some achievements of rural development programs in the research area, provides theoretical and decision-making support for coordinated rural development and ecosystem services protection in China, and provides a regional case study that could assist with similar research in other countries.
