【摘要】：構(gòu)建城市應(yīng)急避難場所避難適宜性評價指標(biāo)體系,采用信息熵模型確定適宜性評價指標(biāo)權(quán)重,利用多指標(biāo)指數(shù)加權(quán)平均值對城市應(yīng)急避難場所進行適宜性評價�；趹�(yīng)急避難場所的入口和周邊應(yīng)急通道網(wǎng)絡(luò)分析應(yīng)急避難場所的服務(wù)范圍。綜合以上分析結(jié)合應(yīng)急避難場所選址原則確定新增應(yīng)急避難場所備選場址。選取中值模型和最大覆蓋模型對備選場所做定量分析,結(jié)合GIS網(wǎng)絡(luò)分析等空間分析技術(shù)進行應(yīng)急避難場所布局綜合決策,確定新增應(yīng)急避難場所最佳位置。形成應(yīng)急避難場所布局優(yōu)化完整方法。研究以廊坊市應(yīng)急避難場所為實例展開,為城市的應(yīng)急避難場所規(guī)劃建設(shè)提供借鑒。
[Abstract]:The evaluation index system of urban emergency shelter suitability is constructed. The information entropy model is used to determine the weight of suitability evaluation index, and the multi-index weighted average is used to evaluate the suitability of urban emergency shelter. The service range of emergency shelter is analyzed based on the entrance of emergency shelter and the network of surrounding emergency channel. The above analysis combined with the emergency shelter site selection principle to determine the additional emergency asylum site alternative sites. The median model and the maximum coverage model are selected to make quantitative analysis of the alternative sites. Combined with the spatial analysis techniques such as GIS network analysis, the comprehensive decision of emergency shelter layout is carried out to determine the best location of the newly added emergency shelter. To form a complete method for optimizing the layout of emergency shelters. The study takes Langfang emergency shelter as an example to provide reference for urban emergency shelter planning and construction.
