基于地理加权和元胞自动机的建设用地发展模拟

为了防止建设用地的肆意扩张,缓解经济和生态平衡之间的矛盾,为政府部门的前期规划工作提供更合理的借鉴。为此以大连市某区域为研究区,将地理加权回归的思想融入到元胞自动机中,实现了城市空间发展的模拟,并与二次logistic回归模型作了对比。结果表明,在土地利用格局与影响因素建模过程中,存在着不同程度的空间自相关性,并在空间结构上不是单一趋势分布的,体现着空间不稳定性。将地理加权回归和元胞自动机的结合,不仅体现了空间分异特征,而且模拟精度也有所提高。     

地价动态监测中数字地价模型建立方法——以武汉市为例

根据《城市地价动态监测体系技术规范》的要求,针对现有地价监测点存在的问题,运用地统计学的理论,利用空间插值充分挖掘地价监测点中的隐含信息,将地价监测点内插生成数字地价模型的原理和方法运用到武汉市地价动态监测中,利用收集的资料建立武汉市数字地价模型,并通过该模型实现地价监测在地价时空分析、基准地价更新、地价信息化建设等方面应用。     

基于C-D函数的吉林省建设用地贡献率区域差异研究

随着城镇化的不断发展,建设用地对经济发展瓶颈作用日益凸显,为合理利用土地资源、优化土地利用结构,探讨土地对经济增长贡献率,以吉林省9个地级市(州)为研究对象,利用C-D函数,对其2004-2011年的建设用地贡献率进行测算,并用ArcGIS 10.0进行聚类,探讨其空间差异及原因。结果表明:1建设用地对经济增长的贡献率在14.05%~55.47%,且存在明显的区域差异,其区域差异主要与自然环境、社会经济条件相关;2建设用地投入对经济社会发展有重要支撑作用;3今后要不断优化产业结构,转变经济增长方式,走科技创新型和资本、资源集约型道路。     

乡村振兴背景下村域尺度国土空间规划：认知、职能与构建

研究目的:在乡村振兴背景下,以国土空间规划体系重构为契机,科学认知村域尺度国土空间规划内涵,明确其基本职能,并提出构建路径。研究方法:文献研究法,综合分析法。研究结果:当前乡村面临转型,而村域规划存在理论认知不深入、技术支撑不足、实施管理困难等问题,新时期村域国土空间规划应依据外部社会背景及村庄内在条件,在全面认知乡村价值前提下,通过空间资源要素配置与用途管制来干预乡村空间重构并服务于乡村治理。研究结论:乡村振兴背景下村域国土空间规划应当具备指明乡村振兴路径、强化乡村空间治理、行使自然资源监管、尊重多元价值诉求等基本职能,并基于问题、需求、目标、行动四维导向进行构建。     

水库库区运营管理政策满意度的空间异质性分析

针对水库库区政策体系因自然资源禀赋差异性导致的政策满意度异质问题,引入顾客满意度理论,基于结构方程模型,构建了异质资源禀赋下库区居民政策感知的结构方程模型,揭示水库库区政策满意度空间分异特征,提出异质资源禀赋下水库库区政策制定的对策建议。并以浯溪口水库为例,应用本文研究框架,探究库区居民政策感知偏好的空间分异特征。     

区域旅游空间结构演化模式分析——以江西省为例

任何成功旅游地的发展必定经历起步、发展、相对成熟和优化4个阶段。旅游系统的各大要素在不同发展阶段具有空间上的不同组合,表现为十分丰富的各种形态和结构。基于此,可根据区域旅游系统空间结构理论及区域旅游系统的内部形态结构和不同发展阶段的特征,把区域旅游空间结构演化模式分为点状模式、放射模式、凝聚模式和扩展模式4种类型。以江西旅游发展为例,改革开放至今江西省旅游空间结构模式经历了点状、放射和凝聚模式,存在区域发展不平衡、旅游客流与交通“瓶颈”矛盾、旅游服务体系不完善等问题,因此必须优化空间结构的目标、措施和模式。     

Optimal Land Development with Endogenous Environmental Amenities

A spatially explicit model of the optimal timing and location of land development is presented that incorporates dynamic interactions between land development and water quality. Ignoring two-way interactions leads to a lower level of water quality, more development, and lower social welfare. The optimal pace and pattern of development can be achieved through the assessment of an impact fee that internalizes pollution damages and irreversibility costs. Our results demonstrate the importance of accounting for the spatial dimension of land use, the interdependence between land use and environmental quality, and development irreversibility in models of urbanization and amenity-driven growth.     

皖江城市带经济差异与其自然地理成因分析

通过2001～2006年的城市经济统计资料的对比,得出皖江城市带的流域经济特征:一是区段性,皖江段处在长江流域经济的低谷,巢湖"大湖经济"不突出;二是差异性,皖江城市带内部发展不平衡,存在东西差异和南北差异,具有流域空间分异特征;从自然地理要素角度来看,断裂、地形地貌差异、洪灾差异、冲洪积平原面积差异以及区域自然地理特征对现代交通布局和航运的影响等是造成皖江城市带经济差异性的自然原因.     

Generational differences: An examination of work values and generational gaps in the hospitality workforce

The purpose of this study is to identify generational differences and similarities among hospitality employees and managers in order to develop leadership strategies and management styles that can be utilized to increase employee morale and productivity while enhancing recruitment and retention rates of highly qualified workers. Data for this study were collected through a series of in-depth focus group discussions. Findings indicated significant generational differences in world views, attitudes toward authority and perspectives on work. Findings suggested the Baby Boomers respect authority and hierarchy, while the Generation X-ers (Gen X-ers) rebel against authority. Findings also suggested while Baby Boomers live to work, Gen X-ers work to live. The Baby Boomers are willing to wait their turn for promotions and rewards, and are very loyal. On the other hand, Gen X-ers expect immediate recognition through title, praise, promotion, and pay. They also want a life outside of work—they are not likely to sacrifice theirs for the company. The Millennial Generation believes in collective action, with optimism of the future, and trust in centralized authority. They like teamwork, showing a strong will to get things done with a great spirit.     

E-Shopping Patterns of Chinese and US Millennials

A conceptually based taxonomy of 22 distinct forms of e-shopping vehicles is proposed. A modification of the UTAUT and UTAUT2 models is introduced to explain how vehicles are interrelated in regard to consumer reliance upon them for their e-purchasing. A survey of over 1,000 millennial university students, 697 Chinese and 306 US, revealed strong support in both samples for the hypothesized six dimensional pattern underlying consumer vehicular reliance. Further, differences between Chinese and US samples lay not in the nature of the dimensions, but rather in the strength of reliance upon each dimension. Thus, the study demonstrates the utility of the concept/measure of shopper vehicular reliance, VPR (Vehicle Purchasing Reliance) for both practitioners and scientists. In cross-national comparisons, observed differences between samples in strength of reliance supported four of five hypotheses predicated on previously established national distinctions a) in trust and b) in the cultural value of individualism-collectivism.
