[Problems and countermeasures of soil health quality in urban green space]

Soil quality of urban green space (UGS) is the basis for ensuring healthy growth of plants and maintaining the healthy ecosystem services for the residents and the sustainable development of city. At present, in order to improve the soil quality of UGS, more attention has been paid to fertility quality and environmental quality, but less to the health quality. We analyzed the concept, connotation, and assessment indicator of soil health quality, summarized the main problems and challenges of soil health quality of UGS. Finally, we put forward the ways and strategies to improve soil health quality of UGS, and prospected future research direction. Our aim was to attract the attention to the soil quality of UGS, especially soil health quality, and the importance of comprehensively improving soil quality of UGS, eventually providing strong technical support for urban sustainable development and eco-city construction.
