The urban development is a decisive factor for the landuse of the territory of Hong Kong, as a realm of a world city. A speed-up
change of the landuse structure of Hong Kong and some contradictions in the landuse have been revealed after a brief mentioning
of the characteristics of the limited land resources of Hong Kong. Hong Kong consists of peninsula and islands dominated by
hilly terrain in south subtropical zone, 84% of the total area is slope, unfavorable for urban and agricultural development,
only 16% is small plains. The land is barren and water resource is very limited. Urban landuse is taken as the dominant factor.
Due to the expansion of the scale of the urban development, and the limitation of the land resource, there is a high degree
of the urban land utilization, but the proportions of commercial and industrial landuse are not high, only 1.3% of the total
developed land is used for commerce, 6.0% for manufacture industries, the road and railway lands amount to 14.6%. The great
efforts were made in reclamation and construction of reservoirs in order to add land and water resources. The arable lands
were reduced heavily and the farmlands were wasted seriously. The author proposed some view points on the present and future
landuse in Hong Kong as follows: 1) the urban landuse remains as a guiding factor in the landuse of the whole territory of
Hong Kong; 2) one of the problems is the fondness for the reconstruction of the old city, loosening up on the new town development;
3) the reclamation is not only very costly, but also causing some negative effects on the eco-environment; 4) the problem
of the protection of the farmlands against wasting should be seriously; 5) the development and the landuse for the construction
in Hong Kong should be considered with the relationship with the inland, especially Guangdong Province; 6) fully use the convenient
condition of the territorial linkage of the city with the mainland, further to bring the role of the Shenzhen Special Economic
Zone into fully play for solving the landuse problems in the development of Hong Kong.
The author is very grateful to Dr. David K. Y. Chu and Dr. Roger Chan for their comments and to Professor Gu Chaolin and Mr.
Hu Tianxin for their helps in data collection. 相似文献

Hong Kong is a hyper-dense city with 7×106 people living in an area of 1100km2. One way to improve the livability of compacted and congested cities like Hong Kong is through the provision of urban parks,
an aspect that has largely been under-researched. This study focuses on how users perceive and utilize various facilities
in the Kowloon Park. The findings revealed that the Kowloon Park is one of the most preferred parks in Hong Kong for both
local residents and tourists. Users were quite satisfied with the park’s facilities. Notably, the most important component
of an urban park is its greenery. This is followed by water elements, seating places, and facilities for various recreational
activities. The improvements users would like to see in urban parks include good design and management, meeting users’ needs,
overcoming barriers to use, and providing a high quality and varied experience for different groups in the community. The
findings of this study provide a good basis to address park management issues from the users’ perspective. In particular,
parks should provide easy access, encourage optimum usage and enable complimentary improvements to the environment.

天气状况作为人们生活环境的组成要素之一,对居民日常出行可产生显著的影响,具体可表征为特定空间位置和用地类型范围内出行活动的需求量以及道路交通路线选择的变化。高效、智能化的交通应急管理和城市规划建设亟需理解天气因素影响交通出行时空分布的基本规律。本文选取武汉市作为典型研究区域,基于出租车、气象和空气质量等数据,对不同天气下的居民出行模式和司机路径选择模式进行时空分析,并解释2类模式产生变化的原因和机制。结果表明：① 从时间上看,工作日的出租车需求量更容易受到天气变化的影响,其中降雨、气温的升高和风速的增强会显著降低居民对出租车的需求;② 从全市域空间尺度上看,降雨使得居民对出租车的需求量在工作日时段减少,而在周末时段增加,其中降雨主要刺激短距离出租车出行需求而抑制中长距离出行需求;③ 从城郊区空间尺度上看,雨天时段主城区内部的中距离流量减少,郊区内部的短距离流量增加,往返于主城区和郊区的中长距离流量在工作日减少、在周末增加;④ 从功能区空间尺度上看,下雨使得行政办公用地的出租车需求量减少,商业金融用地的出租车需求量在工作日减少、在周末增加,工业用地的出租车需求量在工作日增加、在周末减少;⑤ 从行驶路径上看,出租车司机在晴天时偏好根据距离来判断最佳路线,而在雨天倾向于改变原先路线选择策略,将距离和车速共同作为最佳路线的指标,选择用时最少的最佳路线。本文研究成果可帮助城市和交通管理部门更加深入地理解城市居民出行规律及其时空分布特征。 相似文献

人群移动和城市空间结构的关系研究一直是人文地理关注的焦点,它可以帮助理解人群城市空间中移动的潜在动力和影响因素,从而评价城市空间结构的合理性,对城市规划、选址具有重要意义。轨迹大数据为研究城市大规模群体活动、城市空间结构以及二者的关系提供了新视角。本文以人群聚散稳定性为切入点,以深圳市交通小区为分析单元,从社会经济属性、土地利用模式和路网中心性3个方面定量探索城市空间结构特征与人群聚散稳定性的关联性。结果发现：区域的人口数量和密度越大,人群聚散稳定性越低;土地利用混合度越高,均衡性越低,人群聚散稳定性越低;与路网全局中心性比,局部范围内的路网中心性对人群聚散稳定性的影响较大,并且随着距离不同而发生变化。这些知识帮助加深理解人群聚散与城市空间结构特征之间的关系。 相似文献

耦合手机信令数据和房价数据的城市不同经济水平人群行为活动模式研究 总被引：1，自引：0，他引：1
有效分析城市不同经济水平人群的分布特征和活动模式对优化城市资源配置和揭示空间隔离现象有着极高的价值。但人群活动和社会经济等级数据较敏感,使得以往研究仅停留在宏观层面,难以合理划分人群经济等级并对其空间分布和活动模式进行定量分析。本研究以深圳为研究区,基于空间位置关联分析方法,耦合手机信令数据和细尺度房价数据实现了人群经济水平的准确划分,通过计算活动指标定量的分析了不同经济水平人群的空间分布和行为活动特征。研究表明：深圳市不同经济水平人群活动分布与各行政区经济发展相关,呈现“南高北低,西高东低”的格局;深圳市不同经济水平人群之间活动模式存在差异,活动范围、出行距离、出行速度与经济水平存在正向相关;高经济水平人群职住地点相距较远,存在跨行政区分布的现象。本研究分析了城市不同经济水平人群的空间分布特征和活动模式,对城市规划和解决社会不平等问题具有重要的参考价值。 相似文献

Mobile information and communication technologies(MICTs) have fully penetrated everyday life in smart societies;this has greatly compressed time, space, and distance, and consequently, reshaped residents’ travel behaviour patterns. As a new mode of shared mobility, the sharing bicycle offers a variety of options for the daily travel of urban residents. Extant studies have mainly examined the travel characteristics and influencing factors of public bicycles with piles, while the travel patterns for sharing bicycles and their driving mechanisms have been largely ignored. Using one week’s travel data for Mobike, this study investigated the spatial and temporal distribution patterns of sharing bicycle travel behaviours in the central urban area of Guangzhou, China;furthermore, it identified the influences of built environment density factors on sharing bicycle travel behaviours based on the geographically weighted regression method. Obvious morning and evening peaks were observed in the sharing bicycle travel patterns for both weekdays and weekends. The old urban area, which had a high degree of mixed function, dense road networks, and cycling-friendly built environments, was the main travel area that attracted sharing bicycles on both weekdays and weekends. Furthermore, factors including the point of interest(POI) for the density of public transport stations, the functional mixing degree, and the density of residential POIs significantly affected residents’ travel behaviours. These findings could enrich discourse regarding shared mobility with a Chinese case characterised by rapidly developing MICTs and also provide references to local authorities for improving slow traffic environments. 相似文献

当前采用交通流数据量化城市人群活动模式研究已经取得了丰硕的研究成果,但是对于同一区域、同一时段不同类型交通流数据反映城市人群活动模式的共性与差异性仍然知之甚少,直接影响了城市人群活动模式挖掘结果的可解释性与实际应用效果。为此,本文旨在对目前广泛采用的智能卡数据（公交和地铁刷卡）和出租车轨迹数据2种重要的交通流数据,从时空分布模式的差异性、行程距离及距离衰减效应的差异性、空间社团结构的差异性3个方面,探索二者反映城市人群活动模式的差异性：① 采用北京市六环以内区域2016年5月9日至15日的智能卡和出租车轨迹数据进行实验分析,研究发现：① 2种交通流反映出行需求的空间分布呈现出高度相关性,但是在同一空间单元上,2种交通流反映出行需求的时间相关性较低;② 2种交通流的使用率在不同空间位置存在明显差异,仅在城市中心区域使用率较为均衡;③ 2种交通流反映人群行程距离的空间分布、距离衰减效应存在明显差异,公共交通对于促进长距离出行更为重要;④ 从2种交通流发现的空间社团结构都显示了城市的多中心结构特征,但是二者发现社团结构存在的差异性表明两种交通方式对城市空间交互起着不同的作用。本研究有助于深入理解多源交通流反映城市人群活动的内在机理,提升城市人群活动模式在城市规划、交通管理等领域的应用效果。 相似文献

Hong Kong has undergone substantial economic transformations and developed into a sophisticated business and financial center in the Asia-Pacific region,since the return of sovereignty to China as a Special Administrative Region under the One Country Two Systems (OCTS) in 1997.This paper discusses and analyzes the industrial structural changes of Hong Kong in recent decades as well as its future challenges and opportunities.The data and finding reveal that even though Hong Kong will face fierce competition from the Mainland’s cities as the rise of China,the important role as a bridge between China and the rest of the world will brace Hong Kong itself under the OCTS for developing into a service hub for business and trade in the Asia-Pacific region. 相似文献

The transshipment is an important issue in the current marine transportation. This paper constructed a mathematical programming
model to elaborate the transshipment port selection for the shipping company. This model is tested by the data collected from
the ports of Hong Kong and Kaohsiung. The results show that this model can be used to explain the transshipment competition
relationship between the ports of Hong Kong and Kaohsiung well. A sensitivity analysis was also executed. The sensitivity
analysis results showed that both the port of Hong Kong and Kaohsiung should decrease the charges of port and increase the
efficiency of loading and discharging. Based on the sensitivity analysis results, some interesting conclusions and helpful
suggestions were obtained for the managers of the ports of Hong Kong and Kaohsiung to improve their port management. 相似文献

The increasing globalization of the Chinese economy has been enabled by both Chinese financial institutions operating globally as well as international firms operating within China. In geographical terms, this has been organized through a number of strategic cities serving as gateways for the exchange of financial functions, products and practices between China and the global economy. Drawing on location data of financial service firms in China listed on stock exchanges in Shenzhen, Shanghai and Hong Kong, this paper shows that Chinese financial firms are expanding globally and how Chinese financial centers are positioned and connected in the urban networks shaped by these financial service firms. It is found that Hong Kong, China, holds strategic positions in the integration of Chinese cities into global financial center networks, and that establishing a foothold in global financial centers such as New York and London has been a priority for Chinese financial institutions. The increasing capital flows directed by Chinese financial institutions suggests a shifting global financial geography, with numerous Chinese cities playing increasingly important roles within global financial center networks. 相似文献

大数据时代的人类移动性研究 总被引：2，自引：0，他引：2
人类个体/群体移动特征是多学科共同关注的研究主题。移动定位、无线通讯和移动互联网技术的快速发展使得获取大规模、长时间序列、精细时空粒度的个体移动轨迹和相互作用定量化成为可能。同时,地理信息科学、统计物理学、复杂网络科学和计算机科学等多学科交叉也为人类移动性研究的定量化提供了有力支撑。本文首先系统总结了大数据时代开展人类移动性研究的多源异构数据基础和多学科研究方法,然后将人类移动性研究归纳为面向人和面向地理空间两大方向。面向人的研究侧重探索人类移动特性的统计规律,并建立模型解释相应的动力学机制,或分析人类活动模式,并预测出行或活动;面向地理空间的研究侧重从地理视角分析人类群体在地理空间中的移动,探索宏观活动和地理空间的交互特征。围绕这两大方向,本文评述了人类移动性的研究进展和存在问题,认为人类移动性研究在数据稀疏性、数据偏斜影响与处理、多源异构数据挖掘、机器学习方法等方面依然面临挑战,对多学科研究方法的交叉与融合提出了更高要求。 相似文献

The study shows that the regional differentiation of Hong Kong direct investment (HKDI) in China was enlarged in the 1980s
and has been reducing since 1991. The concentration of HKDI in the southern China and the coast has been replaced by the trend
of moving northwards and inlandwards after 1989. But in terms of manufacturing sectors this trend has not clearly appeared
until now. Those changing patterns are clearly related to the behaviour of Hong Kong industrial investors. The survey results
suggest that “enjoying lower production cost” is the most important motive for their investment in China. In consequence,
“close to Hong Kong”, “cheaper labour” and “favourable policy” are major factors for determining the investment locations.
This behaviour, together with the lack of comparison study in location selection among most investors, explains that Guangdong
absorbed most Hong Kong investment in the 1980s. As the production costs have been increasing in Guangdong, some companies
have started to invest in non-Guangdong locations since the end of the 1980s. From the mental map of Hong Kong investors,
however, only some of the non-Guangdong locations are practically attractive.

城市人群聚集消散时空模式探索分析——以深圳市为例 总被引：2，自引：0，他引：2
城市中人群的移动是带有目的性的,城市空间结构功能也存在差异,导致人群在城市中出现聚集或消散的现象,而且该现象会随着时间不断变化。本文基于海量的手机位置数据,以深圳市为例,采用自相关分析识别出城市中人群聚集与消散的区域,然后将这些区域一天中人群聚散组合成时间序列矩阵,采用自组织图聚类方法（SOM）进行聚类得到9种典型的人群聚集、消散时空模式,结合土地利用现状数据,分析解释了每种聚散模式最可能出现的土地利用组合。该研究从聚集和消散的角度探索了城市人群移动的时空模式,进一步帮助理解城市不同区域人群的移动模式以及与城市空间结构功能之间的关系,对城市规划、交通管理具有参考和指导意义。 相似文献

The main purpose of the paper is to introduce the concept of the Global TransPark (GTP). It is a critical time to develop air logistics infrastructure in the New Economy. The paper also presents a brief review of the air cargo industry in the Asian-Pacific region and China, in particular China‘s development in the industry as its economy has grown rapidly and globalized in the past two decades. The paper argues that China needs to develop a GTP to support its future growth, and explains why the Pearl River Delta-Hong Kong-Macao city-region or Extended Metropolitan Region (EMR) is the best location. Finally, it proposes that Zhuhai Airport, one of the five airports in the EMR, is thebest site for the GTP. New policies from Chinese government as well as close cooperation between local governmentsof Guangdong and the two Special Administrative Regions of Hong Kong and Macao will be needed to make the establishment of the GTP possible. 相似文献
