【 摘 要 】

In the light of the characteristics of urban construction activities guided by planning index, this paper puts forward a research method of ecological security which is suitable for the assessment of urban new area planning, and builds the index system of the ecological security assessment of urban new area with the "Driving force - Pressure - State - Response" model. Taking the Qinhan new town in Xixian new area as an example, this method is adopted and the planning plot control indicators are used as the main data source. Ecological security assessments are conducted on 318 planning plots in the new town, and the evolutionary trend of ecological safety after the implementation of the new town planning is assessed. From the perspective of ecological security, it puts forward control opinions for the planning of the new town and provides scientific basis for the decision-making of the planning and management departments of the new town.
