多源数据融合的城市区域型消防风险分布特征研究——以太原都市圈所在区域为例

分析区域消防风险的空间演化特征,针对性建立并调整消防站点,可预见性地降低消防风险。以太原都市圈所在区域作为研究对象,将遥感数据、POI兴趣点数据经标准化处理后融入GIS-GANP模型中,识别城市区域间特异性消防风险因子,探讨区域消防风险系数及空间分布特征,并多角度分析消防站点规划趋势。结果表明:POI数据符合区域融合发展消防风险评估的特异性;太原都市圈所在区域综合消防风险系数偏高,空间上呈45°带状风险分布形态,存在消防韧性、承灾体分布及致灾因子三者关系不匹配的问题,进行风险等级划分,高风险的地区为:太原市的市辖区、清徐县、阳泉市的盂县、吕梁市的孝义市及晋中市的介休市;以太原市为中心城市的都市圈形态非圈层结构;应急管理一体化能够降低公共设施建设成本。

Research on Distribution Characteristics and Planning Trend of Regional Fire Risk Based on Multi-Source Data Fusion——Take Taiyuan Area as an Example

The arrival of an urban society is accompanied by the increase of fire protection risks.Emergency management has weakened the administrative boundaries.The use of integrated planning is the idea and direction to ensure the high-quality development of new urban areas.Grasp the spatial evolution characteristics of regional fire protection risks,establish and adjust fire stations in a targeted manner,and reduce fire risks predictably.Incorporate POI data into the research framework,identify urban area-specific fire risk factors,use the GIS-GANP model to explore regional fire risk coefficients and spatial distribution characteristics,introduce the L-A model,and analyze the trend of fire station planning from multiple angles.The results show that the POI data conforms to the specificity of the fire risk assessment of regional integrated development;the comprehensive fire risk coefficient of the area where Taiyuan City is located is relatively high,with a 45°band-like risk distribution pattern in space,with fire resilience,disaster-bearing body distribution and hazard factors For the problem of the mismatch between the three,the risk levels are divided.The high-risk areas are:the municipal districts of Taiyuan City,Qingxu County,Yuxian County of Yangquan City,Xiaoyi City of Luliang City,and Jiexiu City of Jinzhong City;The metropolitan area with Taiyuan as the central city is a non-circle structure;the integration of emergency management can reduce the construction cost of public facilities.
