RS-based Research on the Space Structure of Yueyang Urban Green Land

摘要

Urban green land is a special ecological system in the city which undertakes the task of "exhaling the old and inhaling the new". The space structures of urban green land will influence and restrict the overall space structure of urban landscape. Based on QuickBird remote sensing image of 2008, this paper aims to translate and extract the space structure information of Yueyang urban green land system with the supporting of GIS and RS. And it combines qualitative and quantitative analysis to analyze the scale, structure and problems of various urban green land specifically including park green land, productive green land, protective green land and subsidiary green land. Finally, the paper generalizes the overall characteristics of green lands of urban districts, and proposes suggestions for future plan of Yueyang green land system in order to improve the overall space structure of existing urban green land system.
