内陆河流域是我国西北干旱区可持续发展的核心支撑区域。有效模拟和评估城市景观过程对流域涉水生态系统服务的影响是该区域可持续发展的重要基础。本项目以黑河流域为案例研究区，采用“揭示机理-发展模型-评估影响”的研究思路，综合利用野外调查、大数据分析、深度学习和情景分析等手段，开展内陆河流域城市景观过程对涉水生态系统服务远近程影响机理和模型模拟研究。将首先综合利用深度学习方法和过程模型揭示城市景观过程对涉水生态系统服务影响机理。然后耦合城市景观过程模型和RHESSys生态水文模型，发展城市景观过程与涉水生态系统服务远近程耦合模型。进而模拟评价流域历史和未来不同情景下城市景观过程对涉水生态系统服务的远近程影响，提出流域城市与山水林田湖草系统管理途径。该研究不仅是当前地理学的学科前沿，而且对于落实我国“生态文明”建设，促进西北干旱区可持续发展具有积极的现实意义。

Inland river basins (IRB) are core areas for supporting sustainable development in northwestern China. The effective evaluation of the impacts of urban landscape dynamics (ULD) on water-related ecosystem services (WES) is an important basis for the sustainable development of this region. This project aims to understand the local and distant impacts of ULD on WES in the IRB. To achieve this purpose, we plan to take the Heihe river basin as the case study area, follow the procedures of “clarifying mechanism-developing model-evaluating impacts”, and integrate the approaches of field surveys, big data analysis, deep learning, and scenario analysis. Specifically, we first intend to combine deep learning with process-based model to reveal the mechanism of the impacts of ULD on WES. Then, we plan to integrate the ULD model and the Regional Hydro-Ecological Simulation System (RHESSys) to develop a coupling model for evaluating the local and distant impacts of ULD on WES. Finally, we plan to assess the historical and future impacts of ULD on WES and propose an approach of systematic management of cities, mountains, rivers, forests, farmlands, lakes, and grasslands in the IRB. This research not only plays a role in the frontier of geography, but also has significance for implementing the construction of "ecological civilization" and promoting the sustainable development of the arid regions in China.
