Using the variable two-step floating catchment area method to measure the potential spatial accessibility of urban emergency shelters
Abstract As a public service facility that provides relief, resettlement, and evacuation services to disaster-affected people, emergency shelters play a vital role in helping people cope with disaster events. The measurement of spatial accessibility of existing emergency shelters is a key task in im...

| 520 | |a Abstract As a public service facility that provides relief, resettlement, and evacuation services to disaster-affected people, emergency shelters play a vital role in helping people cope with disaster events. The measurement of spatial accessibility of existing emergency shelters is a key task in improving emergency shelter services and minimizing property losses and deaths. In this study, considering the differences in emergency shelters’ service capacities and population distribution, we developed a two-step floating catchment area (2SFCA) method with a variable service radius and evacuation radius to describe emergency shelter accessibility in Lanzhou’s core area and compared with the traditional 2SFCA method. Furthermore, we used bivariate local Moran's I to identify the spatial relationships between emergency shelter accessibility and population density. The results show that the traditional 2SFCA method underestimates accessibility in densely populated areas with dispersed emergency shelters. Shelter accessibility in Lanzhou’s core area is unevenly distributed, with the lowest levels of accessibility in densely populated areas. There is an obvious spatial mismatch between the accessibility of emergency shelters and the population density, and the central and western part of Chengguan has a serious shortage of emergency shelters. This study provides important information for the planning and construction of emergency shelters. | ||

The measurement of spatial accessibility of existing emergency shelters is a key task in improving emergency shelter services and minimizing property losses and deaths. In this study, considering the differences in emergency shelters’ service capacities and population distribution, we developed a two-step floating catchment area (2SFCA) method with a variable service radius and evacuation radius to describe emergency shelter accessibility in Lanzhou’s core area and compared with the traditional 2SFCA method. Furthermore, we used bivariate local Moran's I to identify the spatial relationships between emergency shelter accessibility and population density. The results show that the traditional 2SFCA method underestimates accessibility in densely populated areas with dispersed emergency shelters. Shelter accessibility in Lanzhou’s core area is unevenly distributed, with the lowest levels of accessibility in densely populated areas. There is an obvious spatial mismatch between the accessibility of emergency shelters and the population density, and the central and western part of Chengguan has a serious shortage of emergency shelters. This study provides important information for the planning and construction of emergency shelters.

The measurement of spatial accessibility of existing emergency shelters is a key task in improving emergency shelter services and minimizing property losses and deaths. In this study, considering the differences in emergency shelters’ service capacities and population distribution, we developed a two-step floating catchment area (2SFCA) method with a variable service radius and evacuation radius to describe emergency shelter accessibility in Lanzhou’s core area and compared with the traditional 2SFCA method. Furthermore, we used bivariate local Moran's I to identify the spatial relationships between emergency shelter accessibility and population density. The results show that the traditional 2SFCA method underestimates accessibility in densely populated areas with dispersed emergency shelters. Shelter accessibility in Lanzhou’s core area is unevenly distributed, with the lowest levels of accessibility in densely populated areas. There is an obvious spatial mismatch between the accessibility of emergency shelters and the population density, and the central and western part of Chengguan has a serious shortage of emergency shelters. This study provides important information for the planning and construction of emergency shelters.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Disaster management</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Emergency shelter</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Spatial accessibility</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">2SFCA</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Variable catchment size</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Valley city</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Chen, Wenkai</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Cheng, Min</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">GeoJournal</subfield><subfield code="d">Dordrecht [u.a.] : Springer Science + Business Media B.V., 1977</subfield><subfield code="g">87(2021), 4 vom: 21.

Using the variable two-step floating catchment area method to measure the potential spatial accessibility of urban emergency shelters |
| abstract |
Abstract As a public service facility that provides relief, resettlement, and evacuation services to disaster-affected people, emergency shelters play a vital role in helping people cope with disaster events. The measurement of spatial accessibility of existing emergency shelters is a key task in improving emergency shelter services and minimizing property losses and deaths. In this study, considering the differences in emergency shelters’ service capacities and population distribution, we developed a two-step floating catchment area (2SFCA) method with a variable service radius and evacuation radius to describe emergency shelter accessibility in Lanzhou’s core area and compared with the traditional 2SFCA method. Furthermore, we used bivariate local Moran's I to identify the spatial relationships between emergency shelter accessibility and population density. The results show that the traditional 2SFCA method underestimates accessibility in densely populated areas with dispersed emergency shelters. Shelter accessibility in Lanzhou’s core area is unevenly distributed, with the lowest levels of accessibility in densely populated areas. There is an obvious spatial mismatch between the accessibility of emergency shelters and the population density, and the central and western part of Chengguan has a serious shortage of emergency shelters. This study provides important information for the planning and construction of emergency shelters. © The Author(s), under exclusive licence to Springer Nature B.V. part of Springer Nature 2021 |
