Urban Park Green Space (UPGS) is an essential component of cities, with a wide range important services. There keener demand for green space in the process urbanization. Previous studies have extensively evaluated residents' accessibility to space, which belonging UPGS's social service function, but rarely combined ecological conduct refined calculation. This may lead biased results evaluation satisfaction space. Considering scarcity urban land resources, it difficult support efficient use based on these results. To fill this gap, study various functions that UPGS can provide from variety perspectives central Beijing using multi-source geospatial big data. The show that: (1) be overestimated when ignoring eco-service demand. (2) Regions worse or poor largest proportion, and presents obvious low–high-low cyclic structure. (3) peripheral areas are always significant disadvantaged position terms accessibility. Based results, solution further provided by PSO algorithm simulate location new parks solve problem insufficient supply low area. Our better insights city managers formulate effective management strategies references optimization strategy.
