As the most basic travel mode of residents, walking trip takes place more frequently in residential districts. It is of great significance to study the land use characteristics of the residential district suitable for walking in order to create a good walking environment and land use model. In this paper, 18 residential blocks in Xi'an are taken as the research object, based on the relevant data of the pedestrian flow rate and land use of residential blocks, this paper analyzes the interactive relationship between the non-commuting hours during the week, the commuting hours during the week and the weekends by using the multiple linear regression model, and the land use characteristics of residential blocks under the guidance of walking trip are revealed. The results show that the land use factors related to pedestrian flow rate are mainly 9 factors, such as building density, buildings mixing degree, mixing degree of business functions and density of functional formats. In different hours, walking trips have different demands on various elements of land use. During the non-commuting hours during the week, the demand for walking trips for building density, mixing degree of business functions, density of functional formats and footpath area ratio is large. During the commuting hours during the week, the demand for walking trips for buildings mixing degree, density of functional formats, road network connectivity, and green area ratio of footpath is large. During the weekends, the demand for building density, density of functional formats, road network density, and footpath density is large. Through the above analysis, the optimization strategy is proposed for residential blocks in Xi 'an, which provides a theoretical basis for the optimization and transformation of the space environment of residential blocks to promote walking trip.

作为居民最基本的出行方式，步行旅行在居民区更为频繁。研究适合步行的居民区的土地利用特征，对营造良好的步行环境和土地利用模式具有重要意义。本文以西安市18个居民区为研究对象，根据居民区人流量和土地利用的相关数据，分析了一周内非上下班时间之间的互动关系。通过多元线性回归模型，揭示了周和周末的通勤时间，并揭示了步行引导下住宅区的土地利用特征。结果表明，与行人流量相关的土地利用因素主要是建筑物密度，建筑物混合程度，业务功能混合程度和功能形式密度等9个因素。在不同的时间，徒步旅行对土地利用的各种要素有不同的要求。在一周的非上下班时间中，对于建筑物密度，业务功能混合程度，功能格式的密度和行人路面积比的步行旅行的需求很大。在一周的通勤时间内，对建筑物的步行行程的要求是混合程度，功能格式的密度，道路网络的连通性以及人行道的绿地比例。在周末，对建筑物密度，功能格式的密度，路网密度和行人路密度的需求很大。
