城市土地利用混合程度与居民出行空间分布──以南京主城为例

The Research on the Relationship between Degree of Mixed Urban Land-use and Spatial Distribution of Trips: In Case Study of Main Districts in Nanjing

本文讨论了土地利用的混合程度与居民出行空间分布的相互作用关系，明确了城市片区的土地利用混合程度概念与计算模式，并通过城市土地利用、居民出行情况的调查数据与统计结果及趋势曲线，分析土地利用混合程度与居民出行空间分布的作用机理，构建片区土地利用混合程度与片区内部居民出行比例两者之间的关系模型。

In this paper the relationship between the degree of mixed urban land-use and spatial distribution of residents' trips is discussed as well as the working mechanism by the trend curve of investigation data and statistics result of urban land-use and residents' trips. The author defines the concept and calculation models of mixed urban land-use, and the relationship model between the degree of mixed urban land-use in urban districts and the percentage of their residents' trips.
