Abstract:Ground surface hardening is the main results of urban development and expansion. It is also an important factor affecting the urban environment and plant eco-physiological processes.With the analysis of the changes on plant ecological factors caused by ground surface hardening, this study focused on an overview of the effects of ground surface hardening on gas exchange, water balance, nutrient cycling and other eco-physiological processes of plants in urban landscapes. The variation of impacts of different hardness of ground surface hardening, changes of seasons, plants, community structure, and human factors on plant eco-physiological processes in urban landscapes was analyzed and summarized. Thus issues in previous studies were discussed, and suggestions for future research were made. This study might provide a scientific method to optimize the ecological structure of urban landscapes, enhance the plant ecosystem services and improve the living conditions in cities.
