Life After Death

Predictions of the death of impoverished and actively marginalized racial and ethnic communities are premature. Many core African American societies have been devastated by the state, capital, and cultural policies of the last two decades. Simultaneously, geography and the other social sciences have been mobilized in order to prevent a fuller understanding of these communities and of the need for social equity. The further development of several approaches is required to open geography and the other disciplines up for community‐building, rather than community destruction. The incorporation of research in the following areas holds out the promise of revitalizing both: human rights; the ethnic movements underlying restructuring; the social construction of regions; the reproduction of social power; building ethnic alliance; and indigenous knowledge systems.     

Using Spatial Statistics to Examine the Pattern of Urban Land Development in Halifax–Dartmouth

This article examines the locational patterns of population and employment and the resultant changes in urban form in the Halifax–Dartmouth region between 1970 and 1996. The article employs the univariate and bivariate K function to measure spatial dependence or clustering within and between the classes of residential and commercial land parcels. The results of the K function estimates suggest that residential land parcels cluster together, commercial land parcels cluster together, and residential and commercial land parcels have become more clustered over time. Evidence of clustering provides insight into the changing urban form of the region and possible multinucleation.     

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。     

北京西部山地景观生态整治与景观规划--以北京房山区史家营乡的典型研究为例

北京市西部山区是因矿区开发使山地景观生态环境破坏的重点地区,在北京市生态环境整治与建设中具有十分重要的典型意义。不合理的煤炭资源开采导致了矿点密度大,采空塌陷区分布广,水资源急剧减少,水质污染严重,植被大规模遭破坏,水土流失严重,泥石流等灾害加重以及煤尘污染问题突出等一系列环境问题,呈现出山地生态系统遭受严重破坏的景观生态特征。本文以史家营为例,在典型调查的基础上,规划了景观生态环境恢复与重建区、种植养殖和观光生态农业示范区、果粮养殖生态农业区、林草放牧生态畜牧业示范区、生态旅游区的五个景观规划区域,探讨了生态型矿业、中低山特色生态农业和生态旅游发展的产业发展模式,并初步提出了景观生态整治的措施。     

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。     

华南地区小流域水污染控制规划初探

随着经济和城市化进程的快速发展，华南地区小流域水环境污染日趋严重，因此以规划的方法控制该区小流域水污染成为了一种重要的途径。从水环境污染控制规划的基本定义出发，重点分析了小流域水环境污染控制规划的一般规范及其在实施中存在的一些问题，并就这些问题提出了相应的对策，指出小流域进行水环境污染控制时必须加强环境意识，提高环境工作者素质，结合自身实际，走出一条既符合中国国情更符合华南地区小流域的水污染控制规划道路，为华南地区的持续，快速发展创造条件。
