Against the backdrop of growing global awareness of heritage conservation, increasingly sound and relevant legal and regulatory systems, and continuous iteration of conservation philosophies and technical approaches, substantial progress has been made in heritage‑conservation practices. Nevertheless, in the context of historic cities, how to reconcile the physical preservation of heritage sites as material cultural heritage with the sustainable development of urban culture, and how to realize the organic integration of historic‑relic conservation and contemporary urban functional renewal remain critical issues to be urgently addressed ^[1]. In recent years, as a comprehensive spatial paradigm integrating conservation, interpretation and revitalization, “heritage site parks” have increasingly become an important approach to coordinate urban development and heritage protection ^[1]. They not only help strengthen the holistic conservation of heritage sites and their buffer zones, but also facilitate the systematic interpretation and public communication of cultural‑heritage values. As the renowned “ancient capital of eight dynasties” in Chinese history, Kaifeng boasts profound cultural heritage and abundant historic remains, among which King Yu’s Terrace Park serves as a typical representative. Taking urban heritage site parks as the research subject, this paper selects King Yu’s Terrace Park as an empirical case to conduct systematic research on landscape optimization and design ^[2]. The proposed comprehensive renewal scheme balances the authentic conservation of heritage sites, coordination of environmental style and features, and integrity of cultural narratives. It effectively improves heritage recognition and cultural‑bearing capacity of the ancient‑relic conservation zone in the suburbs of Kaifeng. It also carries important practical value and demonstrative significance for furthering the research, dissemination and dynamic inheritance of Song‑Dynasty culture ^[2].
