It studies taxi passenger's daily travel behavior feature: first, it analyzes temporal distribution of them and proposes the solution of dynamic management of taxis by limiting operation period; second, through investigating the uneven spatial distribution of taxi travel demand and nonlinear correlation of travel density and population density, it reveals the shortcoming of linear matching transportion facility with population number in traditional urban transport criterion, also it questions the limited effect of the licence management for taxis, and it proposes dynamically determing taxi scale according to different traffic zones; third, through exploring the taxi travel patterns in special zones, it reveal Hong Kong citizens travel behavior in Shenzhen, which could analyze the impact of demographic feature to the travel behavior and provide scientific testimony for designing transportion service for the special group; fourth, through accurately grasping the spatial-temporal distribution of taxi travel demand, it could provide innotiative and efficient transportion service at different time and in different place, such as taxi-sharing and flexible shuttle to meet the travel demand; through pervasive data, we could inspect urban expansion and sprawl, monitor the separation of inhatitantion center and employment center and reflect the variation of population centriod and distribution; finally, it reveals how to use digital feature of inhabitant daily travel to detect abnormal condition in the city.

对出租车乘客的日常交通行为特征进行了研究：通过对出租车出行时间分布特征的把握，提出采取限时营运的方法来对出租车进行动态管理的思路；通过分析出租车出行空间分布不均匀的特征以及出行密度与人口密度之间非线性的关系，揭示了传统城市交通规范中按人数来线性配套交通基础设施的缺陷以及牌照管理对于出租车管理的有限效果，提出按照区域动态确定营运出租车规模的思路；通过特定区域出租车出行特征的分析，揭示香港居民在深圳的交通行为特征，从而分析不同人口统计特征对于交通行为的影响，为设计这个特殊群体的交通服务提供科学依据；通过对出租车出行时空分布特征精确的把握，使得我们可以在不同时间、不同地点采用创新、高效的交通服务，如合乘出租车，高级穿梭巴士来满足出行需求；通过普适数据可以监测城市的扩张和蔓延、居住中心和就业中心的分离程度以及反映人口重心与分布的变化；最后探讨了如何利用居民日常出行的数字特征来检测城市异常状态。

The dissertation gives a self-contained definition of Complex boundary and interior based on point set topology so that the Complex was consistent with the common description of spatial objects. It is in favor of a unifying between nature description and theory representation of spatial entities in 3DGIS.

本文基于点集拓扑学理论，对复形的边界和内部进行了完备性定义，使得空间实体的复形表达符合人类对空间对象的直观认识，有助于在3DGIS中实现空间实体的自然描述与理论表达的统一。

This paper aims at the prominent issue that current models of spatial topological relations can not represent complex object, among which 9-Intersections Model (9IM) is well known. Therefore, taking cadastral data as example, one model of topological relations between complex and spatio-temporal objects based on 9IM is put forward. And the improved sweep-line algorithm is designed. Specific studies as follows:(1)According to the concepts of point set topology, the author distinguishes the complexity of the object, redefines the spatial point, line and region. For instance, in the simple region, concave one is more complex than convex, composite regions can be composed of many parts or with holes, and so on.

本文针对当前空间拓扑关系模型无法表达复杂对象的突出问题，以地籍对象为实例，以9I模型为基础，探索了一种适合复杂对象和时空对象的拓扑关系表达模型，较好地解决了地籍对象中各类要素间拓扑关系的描述和应用，实现了地籍变更中变化语义类型的推理和历史回溯；通过对现有的拓扑关系计算方法进行了改进，设计了相关算法，给出了C语言程序示例；最后通过实验系统的实现，验证了模型和算法的可行性。

This kind of house absolutely abandons the European and American styles in the architectural design but employs more Chinese traditional residential elements, such as the pitched roof, wall, blue tile and white wall. What's more, especially in the large spatial layout, this building advocates the closed and semi-enclosed spatial arrangement in response to the psychological characteristics of Chinese people, restraint without showiness. However, the interior life circulations without exception absorb the European lifestyle to show the life philosophy and value orientation.

这类住宅的主要特点是在建筑设计上摒弃了完全欧美化的做法，而采纳了较多中国传统住宅的元素，如坡屋顶、院墙、青瓦白墙，特别是在大的空间结构上，提倡封闭、半封闭的空间围合方式，以契合中国人内敛含蓄的心理特征，但在内部生活流线上几乎无一例外地吸收了欧式的生活方式，体现了现代都市人的生活理念和价值取向，项目配套都比较现代化，有公建、会所、游泳池等现代人所不可缺少的休闲和娱乐设施。
