Abstract: As an emerging field in urban heritage preservation, existing research on planning heritage has predominantly focused on individual case studies. Given the lack of large-scale data analysis, the universal planning heritage values embedded within urban heritage projects remain underexplored. This study addresses this gap by examining planning heritage within world heritage. Employing text analysis and data statistics as primary research methods, the study examines urban heritage projects with specific planning heritage values from the World Heritage List. The findings reveal that: planning heritage, with its universal values, is an integral component of urban heritage projects; the values of planning heritage exhibit three characteristics: relative concentration, wide geographic distribution, and diverse combination of attributes; planning heritage serves as an important medium for expressing the cultural connotations of integrity urban built environment. This study demonstrates the universality and diversity of planning heritage values, contributing to a deeper understanding of the integrity in urban heritage.
