Abstract Natural disasters exert an enormous toll on development of society. In doing so, they pose a significant threat to prospects for achieving the ‘Harmonious society goals’ in particular. Cities are complex and interdependent systems, and are extremely vulnerable to threats from both natural and artificial hazards such as earthquakes, fires as well as poisonous gas leaks. Policy, practice and knowledge of disaster mitigation in cities have recently received widespread attention. Community shelters in cities can offer a shelter and emergency rescue for victims and the homeless when disaster occurring. Also it is an important component of urban emergency shelter system. In this paper, AHP method was employed to set up evaluation system of urban community shelters. Results indicate that community parks used as emergency disaster mitigation of shelters is well constructed, with 40% of community shelters are better constructed and 60% of community shelters are medium constructed. However, the infrastructure and daily management relatively low, lack of emergency facilities (fresh water, toilet), enough evacuate exercise and daily education. Meanwhile, the distribution of the overall community parks in Jiaozuo city is too uneven, with high fragmentation index of most patches have an area less than 1.0 ha and their internal safety area is 0 ha are invalid for use as disaster shelter, which makes them insufficient for use as emergency shelters in urban areas. As a result, the service coverage of community shelters is limited, with 24.6% of residents are outside of community shelters service coverage. In service coverage of community shelters, there still have 6.5% of residents with availability of safety zones below 1.05 m2, the minimum per capita requirement for emergency shelters.
