Abstract: Urban green space plays an important role in providing a comfortable living environment. Through literature analysis with the CiteSpace tool, this research explores the hot contents and corresponding technical methods on the articles from the National Natural Science Fund of China (NSFC) related to the urban green space in recent years, and summarizes the existing shortcomings. It mainly focuses on the six aspects: regulation of the microclimate, alleviation of air pollution, assessment of the ecosystem service, landscape pattern, urban green space rate, and promotion of public health. The first two use measurement and simulation as the main research methods. The middle three apply model evaluation, index calculation, difference analysis and spatial analysis, while the latter one is based on model calculation, questionnaires and Structural Equation Model (SEM). The park city and national territory spatial planning are emerging fields of urban green space research, which have continuous research prospects. Finally, it meets major national development needs from the perspective of landscape architecture to provide thoughtful guidance and method reference for the follow-up researches of urban green space.
