快速城市化过程是引起土地利用剧烈变化，并导致生态系统服务也发生相应快速变化的重要人类影响过程。研究城市化过程中土地利用与生态系统服务的动态耦合机制和优化调控，是全球变化尤其是土地利用变化与生态系统服务研究的前沿热点和重点，对城市区域的可持续发展具有重要决策参考价值。项目以滇中城市群为研究区，利用长时间序列遥感数据，结合野外观测数据，模拟城市化过程中的土地利用变化，优化生态系统服务模型，分析近40年滇中城市群土地利用和关键生态系统服务时空演变特征；基于系统动力学理论与方法，集成生态系统服务模型和土地利用模拟模型，形成GeoSOS-InVEST耦合模型系统，探索不同城市化发展模式下土地利用与生态系统服务之间的交互耦合机制和过程；研发时空决策支持系统平台，开展多情景模拟，设计区域最优的土地资源配置方案，提出滇中城市群可持续发展模式。该研究面向领域前沿科学和国家重大需求问题，理论和实践意义明显。

The rapid urbanization process is an important human impact process that causes dramatic changes in land use and leads to corresponding rapid changes in ecosystem services. The research on the dynamic coupling mechanism and optimization control of land use and ecosystem services in the process of urbanization is the frontier hotspot and focus of global change, especially land use change and ecosystem service research. It has important decision-making reference value for sustainable development of urban areas. Yunnan Central urban agglomeration area is chosen as the study area. By combining long-term multi-sources satellite data, intensified field observations, we aim to (1) simulate land use change in the process of urbanization, optimize the ecosystem service model, and reveal the spatiotemporal evolution characteristics of land use and key ecosystem services in the urban agglomeration in the past 40 years; (2) integrate ecosystem service model and land use simulation model, the GeoSOS-IVEST coupled model system is formed to explore the interaction coupling mechanism and process between land use and ecosystem services under different urbanization development modes based on the theory and method of system dynamics; (3) develop a space-time decision support system platform, carry out multi-scenario simulation, design regional optimal land resource allocation plan, and propose a sustainable development model in Yunnan Central urban agglomeration area. This study is targeted to the frontier scientific questions and national important demanding issues, has important theoretical and practical meanings.
