湖北省新型城镇化条件下农民收入增长研究

我国农民收入来源主要包括农业经营性收入、务工收入及其他收入。城镇化发展是农民增收的重要动力之一,十八大以来新型城镇化被提到一个新高度。新型城镇化要求把生态文明理念融入城镇化过程,实现集约、智能、绿色、低碳的发展目标。新型城镇化条件下,农民增收能否持续、高速的发展成为新的课题。文章对湖北省部分市(县)采取实地查勘、问卷调查与走访农户、搜集资料、逻辑分析的方法就湖北省新型城镇化条件下农民增收进行研究。研究结果表明:(1)新型城镇化促进农业现代化发展,提高农产品产值,减少农业产业链内耗,实现农民增收;(2)新型城镇构建农民市民化社会构架,提高了农民工资收入与社会福利收入,增加了农民收入;(3)新型城镇化改变发展模式,增加农民资产性收入与提升了农民生活品质,实现更高水平的增收。研究结论:新型城镇化是未来农民增收最主要的推动力。     

铜川市苹果产业发展研究

现阶段铜川市苹果生产与销售有着大好局面及区位优势,苹果产业的发展对于促进铜川市农业经济的协调发展意义重大。铜川市作为陕西省苹果生产的主产区之一,自然条件较为优越,苹果种植档次及规模逐步提升,形成多个知名品牌,品牌效应不断增强,苹果产业已形成规模化、高度集聚化及规范化管理,苹果产业的发展逐步确立了农户主动参与型、苹果生产基地发展、合作社经营等发展模式,产业链得到了扩展及深化。随着铜川市生产与销售需求的扩大及果农市场意识的增强,建设苹果中心的时机逐渐成熟。但铜川市苹果产业发展仍然面临多样化的问题,如果树较老、缺乏种植技术及人才、缺乏大型种植基地、宣传力度不足、信息闭塞、交易不透明、缺乏公平的苹果交易平台等。文章对铜川市建立苹果中心的支持率、冷库需求进行分析,并进行基本功能规划。在此基础上,提出以政府为引导,形成产业规模;加大基础设施建设;加大宣传力度,提升品牌知名度;促进苹果产业供给侧结构调整等发展策略,为铜川市苹果产业的发展提供理论参考。     

常德市土地利用/覆被变化分析

通过GIS空间分析功能,选取常德市的四个县市:桃源县、汉寿县、临澧县、津市市,从土地利用现状、土地利用时空变化、土地利用类型动态度、土地利用程度变化以及土地利用变化区域差异等五个方面对常德市2009年和2012年土地利用、覆被变化进行定量、定性分析比较。研究结果表明:12009-2012年期间,四个县市的城镇、交通水利等建设用地需求持续增加;2 2009-2012年期间,土地利用程度综合指数呈增长的趋势;3常德市2009-2012年间土地利用程度变化不大,并且区域不平衡;4 2009-2012年期间,四个县市中相对变化最大的为临澧县城镇建设用地。     

基于某办公楼的混凝土结构裂缝研究

钢筋混凝土作为一种脆性材料,由于其早期强度较低,因此,在施工过程中极其容易出现裂缝等缺陷,从而对建筑结构的整体性和耐久性产生很大的影响。目前在工程界最普遍关注的问题就是如何更好的预防钢筋混凝土裂缝的产生以有效保证施工工程的质量。     

加强基础设施建设,提升中心城区的辐射带动能力

在新型城镇化进程中,加强中心城区的基础设施建设、提升中心城区的承载能力、发挥中心城区的辐射带动作用十分重要。本文在分析了黄河三角洲地区中心城市基础设施建设存在不足的基础上,提出了加强中心城区基础设施建设的看法与建议,旨在为全面提升该区域的城镇化水平提供参考。     

从“镇”到“市”实现宁波新型城镇化嬗变

Vicious advice: Analyzing the impact of TripAdvisor on the quality of restaurants as part of the cultural heritage of Venice

Venice is one of the most popular tourist destinations in the world. In Venice, as in other middle-sized heritage European cities, strong tourism pressure is trapping the city in a vicious circle that is eroding the quality of its tourism attractions. This development is related to the growing numbers of excursionists who lack the time to make informed decisions about the quality of goods. Consequently, suppliers reduce the quality of their offerings and instead focus on market share. Consumer-generated media (CGM) may help resist this development by providing excursionists with aggregated, up-to-date information on the quality of tourism offerings as perceived by customers. In this paper, we investigate the efficiency of TripAdvisor in helping tourists to make informed decisions and in increasing the popularity of restaurants offering a higher expected quality. Our findings suggest that, although TripAdvisor's algorithm is designed to reward quality, it does not adequately meet these goals.     

国土空间多功能利用效益评价——以广东省汕头市为例

进行汕头市国土空间多功能利用效益评价,为汕头市科学利用土地,进行国土规划、提高国土利用效率奠定前提和基础。以可持续发展为目的,结合汕头市自然社会发展特点及国土空间利用现状,从社会、经济、资源与生态环境4个功能为切入点,建立4个功能层10个准则层27个指标的国土空间多功能利用效益评价指标体系,并采用熵值法对各功能进行评分。研究结果显示:汕头市国土空间经济功能评分最高,为汕头市国土空间主导功能,其次是经济、资源、环境功能,但社会、文化等功能较弱,各功能缺乏平衡。15年来,汕头市国土空间评价总体评分不断提高,表明国土利用效益在持续提高,但各功能发展不均衡以及人地矛盾依然突出,需要不断加强和完善国土空间规划。     

The Border as a Resource in the Global Urban Space: A Contribution to the Cross‐Border Metropolis Hypothesis

In a globalized urban world, cross‐border metropolises represent a spatial configuration emblematic of the interplay between the space of flows and the space of places. The multiplicity of contexts and processes at work can complicate the identification of what constitutes the singularity of the concept. In order to contribute to these reflections the present article hypothesizes that the specificity of cross‐border metropolises does not fundamentally stem from the form they take or the nature of the cross‐border integration at work, but rather from the particular role played by national borders in their formation. Opening up borders offers new opportunities for border cities and urban border regions to reinforce their positions at the heart of global economic networks, and to affirm their autonomy as cross‐border regional entities. Without minimizing the possible obstructive effects of borders, it is helpful to recognize that they might also represent a resource in the composition of cross‐border metropolitan regions.     

Research agenda for low-carbon mobility: Issues for New World cities

ABSTRACT

Low-carbon mobility (LCM) features strongly in debates about the sustainability of cities and their resilience in the face of demographic, economic, and climate change. Transport is a major source of carbon emissions and there are indications that these continue to increase, despite the considerable recent advances in vehicle, engine, and fuel technologies. Reducing carbon emissions from transport may become more difficult, not easier. A particular issue relates to the New World cities, typified by those of North America and Australasia, which largely developed from the latter half of the nineteenth century onward and whose transportation systems were largely based around private vehicle ownership and usage. These cities are typically composed of low-density, dispersed suburbs, which are highly car dependent and resource and carbon emission intensive. This article develops a research agenda directed at determining and testing policy and planning measures relevant to the quest for low carbon mobility in New World cities. It suggests a rich agenda for essential research on LCM. Much of this agenda falls within the realm of the integration of transport and land use, with attention to urban design details to enhance the perceptions of and opportunities to use low carbon transport alternatives. Research topics identified for LCM research include (1) urban design and land use–transport integration (LUTI), (2) low carbon mobility policies directed at achieving widespread behavior change, (3) opportunities for new technology and its application, including requirements for systems and infrastructure, and (4) analysis and tools for informed decision making, including modeling, measurement, visualization, and especially assessment.
