Abstract:
To reflect the hospital scale and capacity of service more accurately, hospital scale is determined by size of residents, and the search radius is determined dynamically. The spatial accessibility of the main areas in Xi′an city is analyzed by using the original and the enhanced method. The results show the accessibility of main areas of Xi′an city is unequal, midwest is superior to the east, and the spatial accessibility of facilities decreases gradually from the northwest to the southeast. Accessibility is related to the density of street population around the hospital.With the similar hospital, the streets which have fiercer competition of the resource get low accessibility. Accessibility is also related to the hospital scale, under the similar resource competition, the streets with high level hospitals and convenient transportation get high accessibility. The enhanced method can present a more reasonable evaluation of the accessibility so that the differences of same level hospital could be judged efficiently.
