摘要:
 通过运用ARCGIS9.3分析城市安全空间,筛选城市绿地避难场所,根据避难场所的规模确定其服务半径从而计算出加权半径和加权距离。通过运用OVD和WVD方法分别得出避难场所的责任区。结果表明,相比于传统的OVD方法确定的避难场所责任区间的空间关系,使用WVD方法划分的避难场所责任区的覆盖范围更直观,划分的结果也更为合理。
Abstract:
 The urban security space was analyzed by using ARCGIS 9.3 to select urban green shelter. The service radius was determined according to shelter size, and the weighted radius and distance were further calculated. The responsible shelter areas were divided through the methods of OVD and WVD, respectively. Compared to the space relationship between the shelter areas determined by the traditional method of OVD, the coverage of responsible shelter area from WVD method was more intuitive and rational.
