Planning a Prosperous Sydney: The challenges of planning urban development in the new urban context     

Pauline McGuirk  Phillip O'Neill 《The Australian geographer》2002,33(3):301-316

Since their post-war inception, Sydney's metropolitan plans have tended to be overtaken by the social, economic and environmental conditions they have had to confront. The depth and scope of Sydney's recent urban transformation threatens again to overtake metropolitan planning capacity creating, in the context of competitive globalisation, a potentially significant market disadvantage for the city, not to mention poor urban development outcomes. This paper reviews Sydney's post-war metropolitan planning strategies, examining the social and economic contexts and the policy paradigms in which they have been framed, in order to draw out the lessons to be learned from their successes and failures. We argue that future success in planning urban development will rely on richly informed and fine-grained understanding of the complex spatial outcomes of Sydney's ever-deeper global integration. Only such fine-grained understanding can empower metropolitan planning to be responsive to the evolving challenges of managing development in the contemporary urban context.  相似文献   

RURAL PLACE ATTACHMENT IN HISPANO URBAN CENTERS*     

JEFFREY S. SMITH 《Geographical review》2002,92(3):432-451

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.  相似文献   

Alpine medicinal plant trade and Himalayan mountain livelihood strategies   总被引：5，自引：0，他引：5  

Carsten Smith Olsen  Helle Overgaard Larsen 《The Geographical journal》2003,169(3):243-254

Commercial alpine medicinal plants are collected from the wild by local rural households throughout the Himalaya and sold in order to increase household incomes. Recent studies indicate that this annual trade amounts to thousands of tonnes of roots, rhizomes, tubers, leaves, etc., worth millions of US dollars. The main market is in India. Based on a national survey, including the most commonly traded species, and a village study this paper investigates the importance of the alpine medicinal plant trade at national and local levels in Nepal. The national survey included standardized open-ended interviews with 232 harvesters, 64 local traders, 66 central wholesalers, 47 regional wholesalers, and 16 production companies. The village survey is based on the daily records of household activities in 15 households in a one-year period. The annual Nepalese alpine and sub-alpine medicinal plant trade is conservatively estimated to vary from 480 to 2500 t with a total harvester value of US$0.8–3.3 million; the average harvester value is estimated at US$66.0 ± 99.0. The trade in 1997/98 amounted to 1600 t with a harvester value of US$2.3 million and an export value equivalent to 2.5% of total export from Nepal. Medicinal plant harvesting was found to constitute an integrated part of local livelihood strategies, contributing from 3 to 44% (average of 12%) of the annual household income. Importance at household level depended on land and animal holdings, and the availability of adult male labour. The validity and reliability of methods and analyses is evaluated, and issues of conservation and management of alpine medicinal plant species under the community forestry scheme are discussed.  相似文献

东莞城市化过程中若干问题研究   总被引：10，自引：3，他引：10  

黄靖 《地理与地理信息科学》2003,19(5):73-76

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。  相似文献   

基于农用地价格体系的征用地价应用研究   总被引：5，自引：0，他引：5  

李强  马仁会  王秋香 《地理与地理信息科学》2003,19(6):56-59

农用地价格体系和估价成果应用是当前农用地定级估价工作的难点和争论焦点，该文提出了农用地价格体系应以资源基准地价为基础，通过一系列修正，得出分级分区的征用基准地价、不转变用途的农地流转价、转变用途的农地转用价；以佛山市南海区的农用地估价成果为例，就其与现行征地补偿标准进行了比较，并与南海城区、广州市区城镇建设用地基准地价的相互衔接性进行了验算，应用成本逆推法，从城镇基准地价导出建设用地生地地价，在内涵一致的条件下相互比较。结果表明，按此地价体系建立的农用地征用价能够与城镇地价相衔接，可为城乡地价一体化的建立提供实证。  相似文献

王云才  郭焕成 《山地学报》2003,21(3):265-271

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。  相似文献
