摘　　要：基于问卷调查数据,分析了北京不同区县居民的工作出行分布指数、全北京居民工作出行分布指数及不同社会经济群体的工作出行分布指数,并根据出行分布拟合函数分析了北京工作出行分布的变化规律。研究表明,较高收入人群围绕工作地的居住分布较为分散,随着出行距离的增加,分布指数下降相对较缓;反之,较低收入人群的居住分布相对较为紧凑,并随出行距离增长快速下降。反映出随着收入的增加,居民可以更为自由地选择居住空间。本研究将为进一步构建北京LUTI模型、开展城市空间政策检验、实施可持续性模拟分析研究奠定基础。Based on the home interview data, we analyzed the work trip spatial distribution of different zones, the whole Beijing city, and different social groups. As a result, we established the modeling fimction of Beijing work trip distribution. It is demonstrated that residents with higher income are more dispersed around their work place, with the trip distance increase, trip index decreases more slowly; on the contrary, residents with lower income are laid less dispersedly, with trip distance increase, commute distribution decreases faster. We quantitatively reached a conclusion that people with higher income in Beijing are less constrained by trip distance. Our research would lay a base for the establishment of Beijing LUTI, and would contribute to experiments of urban spatial policy and the realization of sustainable development.
