【 摘 要 】

Under the background of urbanization, rational use of limited land resources and scientific analysis of the ecological bottom line of urban development have very important practical significance. Taking the typical Zhaoqing city of the Pearl River Delta as an example, using the landscape safety pattern theory, through GIS technology analysis and simulation of the city's geology, hydrology, biodiversity and local cultural heritage spatial pattern, analyzing the key factors of safety development, and identifying the ecological development of the city. The bottom line protects sensitive areas of ecosystem services, builds a comprehensive urban security landscape, and achieves scientific and healthy development in the process of urban expansion.
