| 摘 要： | 提出了一个在GIS环境下利用时空棱镜确定可达的活动场所位置组,再由活动场所内外条件特性及其位置特点提供的吸引率决定最终活动目的地的选择。讨论了在GIS环境下时空棱镜的操作定义,通过分析影响人们选择目的地的几项因素,提供了计算活动场所吸引率的数学公式。并在MAPGIS软件平台上予以实施,通过宁波一小城区中的生活购物行为例子,进行了检验。

| 关 键 词： | 时空棱镜 潜在路径区域 活动场所吸引率 最短路径 |

| Abstract: | The manipulation definitions of space-time prism within a GIS are discussed,the formula for calculating attracting ratios of the establishments is offered by analyzing the affecting factors of destination choice.The parameters estimation of the formula can use least-squares estimation(LSE) by use of the pratical survey data in research area which are grouped according to activity sorts and people behavior characteristics.The system based on the destination choice model is developed in MAPGIS environment.That is tested by a shopping case in a small zone belonged to Ningbo city. |

| Keywords: | space-time prism potential path area attracting ratio of the activity opportunity establishment the shortest path |
