张家口市景观格局及旅游生态服务价值演进研究（英文）

北京冬奥会部分项目于2022年在张家口举办，张家口作为重要的冰雪旅游地，在其建设过程中其景观格局的变化速率、景观生态安全水平、生态系统服务价值尤其是旅游生态服务价值的研究极为必要。本研究运用2000–2020年间的土地利用数据，综合分析张家口土地利用动态度、土地利用转移矩阵、景观脆弱度、景观干扰度、生态系统服务价值、旅游生态服务价值等的动态变化。结果表明，2015–2018年张家口市景观格局发生大幅扰动，景观生态安全在景观格局调整的过程中受到威胁，直至2020年景观格局经过调整并稳定以后，景观生态安全重新恢复，生态系统服务价值尤其是旅游生态服务价值得以显著提升。本研究结果将为张家口冰雪旅游地景观格局的优化，以及旅游生态价值的提升起到重要的推动作用，同时，可对我国其他冰雪旅游地的发展提供重要借鉴。

Evolution of Landscape Pattern and Tourism Service Value in Zhangjiakou City

Zhangjiakou is a northern Chinese city that hosted the Beijing 2022 Winter Olympic Games. As an important ice and snow tourist destination, it is essential to investigate Zhangjiakou's rate of landscape pattern change, the landscape ecological security level, and ecosystem service value, particularly the tourism ecological service value during its construction. With land use data from 2000 to 2020, this study comprehensively analyzed the dynamic changes in Zhangjiakou, including land use dynamics, the land use transfer matrix, landscape vulnerability, landscape disturbance, ecosystem service value, tourism ecological service value, and other aspects. The results show that the landscape pattern in Zhangjiakou was greatly disturbed from 2015 to 2018, and the landscape ecological security was threatened in the process of landscape pattern adjustment. By 2020, after the landscape pattern was adjusted and stabilized, the landscape ecological security was restored, and the ecosystem service value was significantly improved, especially the tourism ecological service value. The results of this study will play an important role in promoting the optimization of Zhangjiakou's ice and snow landscape pattern and the improvement of tourism ecological value. In addition, it provides important lessons for the development of other ice and snow tourist destinations.
