[Background] Considering the context of urban stock renewal and the increasing demand for urban physical examination and assessment, urban parks in older urban districts are experiencing progressive issues such as functional decline, aging infrastructure, and limited adaptability. These challenges hinder eff orts to enhance high-quality living environments. As important carriers of ecological services, public life, and cultural experience, comprehensive urban parks require more precise diagnostic tools than those provided by conventional normative assessments. Existing evaluation approaches often rely on single-source data, static indicators, or highly subjective judgments, which impede the identifi cation of structural defi ciencies and the implementation of targeted renewal initiatives. Consequently, this study proposes developing a multidimensional diagnostic framework for the comprehensive physical examination and evaluation of urban parks. [Objective] This study aims to construct a diagnostic evaluation system for urban comprehensive parks that encompasses three interconnected dimensions: landscape services, operational management, and development potential. The purpose is to identify key constraints in the renewal of existing parks, support targeted governance and improvement, and provide a methodological reference for refi ned renewal and sustainable park-city development.
