Abstract: The urban green space survey is a basic work of landscape planning, construction and management.The accuracy of data has a direct impact on the scientific development of urban landscaping. This paper puts forward a technical method of synergetic remote sensing survey and ground survey of the urban green space. By comparing the data obtained under this scheme and the data acquired in exclusive remote sensing survey or ground survey, it could improve the timeliness and accuracy of urban green space survey, especially park green space and attached green space survey, providing operational technical methods for urban green space surveys.
