Research on Site Selection for Disaster Prevention and Refuge Green Spaces Planning with GIS-AHP

Abstract

Purposes The construction of disaster prevention and refuge green spaces is crucial in urban safety engineering. Taiyuan City has made significant efforts in urban construction to enhance its capacity to respond to possible disasters. However, challenges persist, including insufficient quantity, unreasonable distribution, and lack of scientific quantification in site selection. Methods To address these issues, the current status and the selection planning of disaster prevention and refuge green spaces in Taiyuan City were investigated in this study. Factors influencing the selection of such spaces were identified, and their weights were calculated by using the Analytic Hierarchy Process. Spatial analysis was conducted by using GIS technology to derive scientifically grounded site selection results. Finally, by taking the Yingze District of Taiyuan City as the object, specific site selection recommendations were proposed. Findings The proposed method can offer a scientific theoretical foundation for the selection of disaster prevention and refuge green spaces in Taiyuan City, making professional contributions to enhancing urban disaster prevention and refuge capabilities and constructing ecologically livable cities.
