Abstract: From the perspective of urban disaster prevention and control, this paper expounded the relationship between urban disasters and the evolution of urban space, the comprehensiveness and systematicness of urban disaster adjustment. The status and function of green space system in adjusting urban disaster and maintaining public health were also clarified. And then, this paper explored and proposed the planning concepts and strategies of green space system to adapt to urban disasters from multiple levels（human and nature, source prevention and control, combination of disaster prevention and control, coordination of rigidness and elasticity, post-disaster restoration） and multiple scales（regional, urban, group, community, park and unit）. The following conclusions were put forward. Regional scale construction of green security pattern is conducive to prevention and control from the source of urban disasters. The layout of elastic "reservation of green space" in urban scale can provide sufficient emergency shelter space in case of urban disaster. The construction of rigid "green complex" can guide the orderly development of urban space and alleviate the occurrence of "big city disease" Community greenway construction at community scale can provide green safe passage for urban residents. The organic creation of open space and micro-isolated space at the scale of the park can increase the richness of the activity space for visitors, and also improve the function of disaster prevention and protection and use efficiency of the green space in the park. Small and micro green space in the scale of health unit can provide zero distance healthy and safe outdoor activity space for urban residents in special periods of time. It is hoped that these viewpoints can provide reference for the healthy and sustainable development of urban living environment.
