Evaluation and comprehensive improvement path of county-level emergency rescue capacity in Qinghai-Tibet Plateau National Park Cluster

Methods such as time cost accessibility, accessibility under maximum coverage, cost distance and mobile two-step search method were adopted to assess the emergency rescue capacity of counties in the Qinghai-Tibet Plateau National Park Cluster. Combined with GIS overlay analysis and statistical analysis methods, the comprehensive improvement path of county-level emergency rescue capacity in Qinghai-Tibet Plateau National Park Cluster was constructed. The results show that: (1) The number of firefighting facilities in Qinghai-Tibet Plateau National Park Cluster at county level was seriously inadequate, with the supply being dense in the east and sparse in the west. There were significant inter-provincial differences in police facilities, and the per capita ownership was insufficient. The construction of emergency shelters was imbalance in space, and the shelters was outdated. (2) The overall time accessibility of firefighting facilities in Qinghai-Tibet Plateau National Park Cluster at county level was poor, with a basin-type spatial distribution characterized by high in surrounding area and low in middle area. The spatial accessibility of police facilities was generally poor, which were still unable to meet the emergency rescue needs of National Park Cluster. (3) Improving the layout system of firefighting facilities, optimizing the spatial allocation of police facilities, and balancing the spatial distribution of shelters have become the main paths to improve the emergency rescue capacity of the Qinghai-Tibet Plateau National Park Cluster.
