Abstract:The water system of the Chengde Summer Resort is naturally coherent. At the beginning of the construction of the garden, the lake was once a marsh after the eastward movement of the Wulie River. Later, it was manually excavated to guide the Wulie River water into the garden. It has formed a natural landscape garden with water as the main body supported by the water conservancy project. Comprehensively sort out the development and historical changes of the water system of the Chengde Summer Resort, and combine the traditional water culture thoughts, analyze the water management methods of the water system. Provide a reference for the research and protection of the world water heritage landscape.
