中文摘要： 生态系统服务权衡协同研究是深入理解生态系统服务机理，拓展和深化地理学和生态学过程研究的核心议题，也是制定生态管理策略，实现社会经济可持续发展的关键。汾河上游流域是山西省会太原市唯一的水源涵养地和晋中盆地重要的生态屏障；本研究以汾河上游流域为研究区，在ArcGIS软件支持下，通过定点观测、野外调查、统计资料收集，采用InVEST模型模拟，对过去30多年水源涵养、土壤保持、产水量，水质净化、植被净初级生产、农产品生产等生态系统服务进行定量制图；基于服务簇和布尔网络对生态系统服务权衡和协同关系的空间格局和时间动态进行定量分析；采用典型相关分析和矩阵迭代方法，对权衡和协同驱动机制进行探讨。试图在两个方面有所突破：(1)构建生态系统服务权衡/协同定量分析框架；(2)生态系统服务权衡/协同驱动机制定量分析方法。

英文摘要： Quantification of the tradeoffs and synergies among ecosystem services is key to exploration of generating mechanisms of ecosystem services, and conducive to prudent ecological management policies. The Upper Fenhe watershed is the only water source for Taiyuan City, the capital of Shanxi Province, and provides an important ecological shelterbelt for Jinzhong basin. This study take the Upper Fenhe watershed as a study area, mapping the ecosystem services of water conservation, soil conservation, water yield, water purification, NPP production, and agricultural production for the past 30 years, by application of InVEST model backed up by on-spot investigation, field surveying, and statistical data collecting. By combining the methods of bundle and Boolean network, this study plans to quantify the spatial pattern and temporal dynamics of tradeoffs and synergies among ecosystem services. The driving mechanism is also explored by CCA and matrix iteration methods. The study attempts to make breakthroughs in: (1) establishing a framework quantifying tradeoffs and synergies among ecosystem services, and (2)exploring the driving mechanisms underlying these tradeoffs and synergies.
