Abstract: The construction of urban ecological green spaces contributes to the development of urban ecosystem and the improvement of public well-being. The exploration and clarification of key factors influencing the ecological aesthetic of urban green spaces is of important significance to the construction of healthy and stable ecological landscape and the guidance of public ecological values. By exploring the concept and connotation of ecological aesthetic, and summarizing the characteristics of green spaces in compliance with ecological aesthetic, this research proposed the following principles and countermeasures for the construction of urban ecological green spaces based on ecological aesthetic: classified urban green spaces into three types (ecological conservation type, ecological function type and ecological landscape type) by referring to the ecosystem service functions and basic conditions of urban green spaces as well as the interference of human activities to facilitate the construction of an ecological green space network; proposed six types of natural plant community configuration patterns in combination with the species composition, spatial layout and functional needs of green spaces. The aim is to provide a planning basis for the construction of green space landscape with high ecological efficiency and landscape quality.
