As a fundamental component of urban green infrastructure, park green spaces demonstrate a profound interactive relationship between diverse habitats and soil quality. Nevertheless, existing soil-related standards for park green spaces in China predominantly concentrate on pollution risk control or meeting basic fertility criteria. They lack a dedicated indicator system focused on “enhancing plant diversity and adapting to habitat functions,” which impedes eff orts to create diverse park habitats. This study systematically sorts current national standards, industry specifi cations, and local practical standards, overcomes the limitations of traditional single-dimensional evaluation, and constructs a comprehensive evaluation indicator framework across three aspects: physical and chemical properties, pollution status, and biological characteristics. By combining the characteristics of the “construction - management - maintenance” stages with diff erences among homogeneous, heterogeneous, and linear habitats, it designs a dynamic sampling and diff erentiated monitoring plan. Following the principle of “prevention fi rst, process control, and result verifi cation,” it establishes a full-process quality control system covering “sampling point layout - sampling - determination - data,” and implements specifi c quality control measures for habitats such as waterfront areas and rooftop greening. The technical system developed in this study can provide standardized, normalized method references for soil investigation and monitoring of park green spaces and help accurately match soil quality with habitat functions.
