摘　　要：为明确城市轨道交通站点吸引范围及吸引强度,提出轨道站点多接驳方式吸引范围及吸引强度模型。基于轨道交通最主要接驳方式,将轨道站点吸引范围分为直接吸引范围及间接吸引范围两类。考虑站点空间特征,分别提出基于阈值的点阵算法及灰色距离衰减模型研究直接和间接吸引范围。在此基础上,构建了轨道交通站点的多接驳方式吸引强度模型。结果表明:直接吸引范围不是规律的圆形,各站点直接吸引范围不相同,随着距离的增大,直接吸引强度呈现逐渐减小的趋势;间接吸引范围中,各站点的间接吸引范围同样存在差异,随着距离的增大,间接吸引强度呈现先降后增再降的趋势。To clarify the catchment area and attraction intensity of urban rail transit stations, models of catchment area and attraction intensity of multi-connection modes of urban rail transit stations are proposed. Based on the main connection modes of urban rail transit, the catchment area of rail transit station is divided into direct catchment area and indirect catchment area. Considering the spatial characteristics around the station, lattice distribution algorithm based on threshold and grey distance delay model are proposed respectively to study the direct and indirect catchment area. On this basis, the attraction intensity models of multi-connection modes are constructed. The results indicate that: the catchment area of direct connection mode is not a regular circle, and the direct catchment area varies from stations. The attraction intensity of direct connection mode decreases gradually along the distance. For the indirect catchment area, the catchment area of indirect connection mode varies from stations, too. With the increases of the distance from the station, the indirect attraction intensity decreases first, then increases and then decreases.
