Faced with limited land resources, large and medium-sized cities are compelled to make use of land in an efficient and intensive way. At the same time, the available traffic resources in many cities cannot meet the soaring trip demands. From the perspective of bicycle travel, this paper explores the characteristics of land use and bicycle travel in different types of urban blocks in Xi’an, based on the data collected from field surveys, cellular signaling data, Mobike and other sources. Through correlation analysis, the indices of land use were screened, forming an evaluation index system. On this basis, a model of the relationship between the proportion of bicycle travel and land use indices for each type of blocks was established. Finally, the interval under each land use index was optimized to promote bicycle travel in some blocks. According to the research results, there is a positive correlation between the land intensity of Xi’an city block and the bicycle travel ratio within a certain range. However, when the land intensity exceeds a certain value, bicycle travel will be inhibited. The interval values of the three types of land use indicators are as follows. It is recommended that the range of floor area ratio for the first ring is between 2.18 and 2.25, and the range of mixing degree is between 0.43 and 1.16. It is recommended that the range for the floor area ratio of the second ring is between 2.63 and 3.50, and the mixing degree is between 0.98 and 1.43. It is recommended that the range for the floor area ratio and mixing degree of the third ring should be between 1.52 and 1.80 and 0.72–1.38, respectively. The purpose of this study is to provide reference methods, ideas and operational indicators for the optimization and reconstruction of land use.

面对有限的土地资源，大中型城市被迫高效而集约地利用土地。同时，许多城市的可用交通资源无法满足飞涨的需求。从自行车出行的角度出发，本文基于实地调查，蜂窝信号，Mobike等来源的数据，探索了西安市不同类型城市区的土地利用和自行车出行的特征。通过相关分析，筛选出土地利用指标，形成评价指标体系。在此基础上，建立了每种类型街区自行车出行比例与土地利用指数之间关系的模型。最后，优化了每个土地使用指数下的间隔，以促进某些区域的自行车旅行。根据研究结果，西安市区的土地强度与自行车出行率在一定范围内呈正相关。但是，当陆地强度超过一定值时，将禁止自行车行驶。三种土地利用指标的区间值如下。建议第一个环的容积率范围在2.18和2.25之间，混合度的范围在0.43和1.16之间。建议第二个环的表面积比率的范围在2.63和3.50之间，并且混合度在0.98和1.43之间。建议第三环的容积率和混合度的范围分别在1.52和1.80和0.72-1.38之间。这项研究的目的是提供参考方法，
