RURAL PLACE ATTACHMENT IN HISPANO URBAN CENTERS*

ABSTRACT. Continued rural‐to‐urban migration has helped motivate cultural geographers, long suspected of having a rural bias, to include urban areas in their purview. Patterns of gender, class, ethnicity, and commercialization have proved to be fertile subjects for research, but the elastic links between rural and urban places are not yet well understood. Hispanos, despite intense feelings of loyalty to their rural villages, moved en masse to cities in the 1940s. By the 1950s a majority of Hispanos were living in regional urban centers of the upper Rio Grande country, where wages were higher and employment was secure. This Hispano experience is a crucible for examining how urbanites' attachment to rural places is manifested in various cultural expressions brought from country to city: painted murals, burial preferences, popular music, and irrigation ditches. Understanding threads of rural culture that have been incorporated into the urban fabric in turn leads to clearer comprehension of the emotional attachment that urbanites have for rural areas and a better appreciation of the complexity of the urban cultural environment.

东莞城市化过程中若干问题研究

改革开放以来，东莞市积极吸纳海外资本与技术，通过“三来一补”企业的快速发展，带动了非农产业和小城镇的迅速发展。然而，受我国分散的工业化和农村城市化政策体制的影响，在快速城市化过程中也暴露出很多值得关注的问题。该文基于实地考察与问卷访谈，重点分析了土地利用效率低、外来人口集中以及基础设施建设与城市经济发展不相协调等问题，并提出协调城市化发展的对策。     

城市功能区划的数量化方法研究及其应用--以深圳市南山区物流中心选址为例

文章总结了以往国内学者对城市功能区域的数量化方法研究，认为在层次分析法等方法中对指标权重的确定存在主观因素过多等不足，严重影响了研究的科学性和准确性，文章为了克服上述不足，将多属性效用理论的代理价值法与博弈论的方法应用于城市功能区的布局与研究，并以深圳市南山区物流中心的选址为例，阐述了代理价值法与博弈论在城市功能区域中的具体实践操作。     

西方城市空间结构研究的理论进展

文章综述了西方国家城市空间结构研究的理论进展，概括了城市空间结构各时期研究的主要内容和理论观点，展望了城市空间结构未来研究的趋势和方向。工业化以前西方城市空间结构研究主要侧重于城市表面形态的揭示，把城市空间结构同发展过程分离开来论述其特性。工业化以后的城市空间结构研究进展十分迅速，在研究中十分重视引入新思想、新理论、新技术和新方法。在不同时期出现了不同的学术派别，并总结出诸多城市空间结构的理论模型。     

三峡库岸城区滑坡治理与沿江公路建设一体化模式--以重庆万州清泉路滑坡为例

三峡库岸城区滑坡90%属于由第四纪松散土体组成的散体滑坡,滑坡区属于城区重要组成部分,降雨及三峡库水位降落是此类滑坡孕发的动力因素。本文以重庆万州清泉路滑坡为例,基于库岸城区滑坡防治原则,构建了实用的滑坡治理与沿江路建设一体化模式,推导了抗滑桩的内力计算方法;详细分析了一体化模式的结构组成及受力特性。研究成果对于三峡库区城区滑坡的治理与开发利用具有较强的指导借鉴作用。     

盐碱化湿地稻-鱼复合生态系统微生物特征

为揭示盐碱化湿地稻-鱼复合生态系统微生物群落结构特征,1994-1995年,对松嫩平原苏打盐碱化湿地稻-鱼复合生态系统水体与土壤中的微生物数量及种群组成进行了初步研究。结果表明,稻-鱼湿地水体中异养细菌数量显著高于稻田湿地(P<0.05),季节变化特点为秋季>夏季>春季。异养细菌的数量分布与鱼产量有显著相关关系(r=0.879)。稻-鱼湿地系统的土壤微生物数量明显高于稻田湿地(P<0.01)。稻-鱼湿地和稻田湿地分别检测出10个和11个属的异养细菌。稻-鱼湿地系统1个生长期细菌的平均生物量为0.973g/m3,生产量为307.5 kg/hm2,所提供的鱼产力为7.0 kg/hm2。     

'In the shadow of hierarchy': meta-governance, policy reform and urban regeneration in the West Midlands

This paper explores the relationship between political hierarchy and the complex webs of political organization associated with urban governance. Deploying the concept of meta-governance and a study of urban policy reform in the West Midlands region of England, this paper claims that state and governmental hierarchies continue to have a crucial role in coordinating the activities of governance regimes in the UK. This paper concludes by considering the effects of hierarchical power on the systems of political participation and representation that are associated with urban governance.     

Population and environment in Australia: issues in the next half century

This paper considers the likely future population in Australia to 2050 and is cast within the context of environmental limitations, to which Griffith Taylor alerted the nation in the 1920s and 1930s, and for which he was vilified in several quarters. While acknowledging the relative accuracy of his long-range forecasts, the arguments here depart from environmental determinism, although varying sets of environmental ethics and values are considered in relation to Australia's global responsibilities and international commitments. It is argued that an increase in population to 26 million by 2050 will not place severe stresses on the physical environment, provided environmental and resource management strategies are put firmly in place, and if consumption and resource use practices are significantly modified. An ideological linkage exists between a resurgent Australian nationalism and a number of environmental perspectives, but one which rejects growth and biological diversity among humans while embracing environmentalism. This inward-looking nationalism–environmentalism is seen as harmful both to Australia's moral integrity as a nation, and in local and world citizenship.
