ABSTRACTAs a tribute to the massive contribution of our friend and colleague Graeme Hugo to the population and settlement geography of Australian rural areas, this paper presents a longitudinal study from his home State. It forms part of a wider study of the long-term demographic relationships between Australia’s rapidly growing regional cities and their surrounding functional regions. Of particular interest is the question of what effect the accelerating concentration of population and economic activity into a given regional city will have for the longer term demographic sustainability of its functional region as a whole. Taking the case of Port Lincoln, regional capital of most of South Australia’s Eyre Peninsula, it examines the nature of change in the functional region over the period 1947–2011, and investigates the forces feeding, and partly counteracting, the population concentration process, informed by concepts of evolutionary economic geography. In particular it traces the demographic impact (particularly differential migration and ageing trends) of exogenous shocks to the region’s essentially primary productive economic base during the period of major change from 1981 to 2011. 相似文献

近代由于气候的变暖,工业化进程的加快,人口的激增,森林的过度砍伐,草场的超载过牧,化学制品的滥用,环境的污染,生态环境遭到了严重破坏,生物物种灭绝速度较单纯自然状态下的速度要快1000倍。生物物种灭绝对人类生产、生活,甚至对人类生存都构成巨大的威胁。因此,应对气候变化,保护生物多样性,防止物种灭绝,已成为全球性的紧迫任务;中国是世界生物物种资源最丰富的国家之一。中国生物多样性形势总体严峻。中国政府高度重视生物多样性保护工作,先后颁布一系列法律法规,已收到巨大成效;保护生物多样性确保世界粮食安全,是全球人民的普遍愿望。生物灭绝关系人类存亡。人类要秉承天人合一的理念,与大自然和谐相处。 相似文献

The transition in the Slovenian countryside is examined through a case study of Cirkovce, a local centre for the central southern
section of the Dravsko polje plain where natural and socio-geographical factors underpin a mixed rural-urban structure. Farming
is intensive, but a high percentage of people are now employed outside agriculture; a situation which is reflected clearly
in the appearance of the settlement. The process of rural depopulation, balanced by the growth of employment in industry and
services, is reflected in a secondary knot of settlement around Cirkovce's railway station. Agriculture is still very significant
but there needs to be some consolidation of landholding to create larger units suitable for market production and food processing.
But the village must also improve its range of functions and provide a better environment for the non-agricultural population
which will become increasing important for its future development.
This revised version was published online in July 2006 with corrections to the Cover Date. 相似文献

This paper analyses the ‘Dorferneuerung’ or village renewal scheme - a key policy for rural development in the new ‘Länder’ of Germany which has been transferred from the old Länder. The contribution that Dorferneuerung can make to rural development is considered, with particular reference to the experience of participating villages in Sachsen-Anhalt. It concludes that Dorferneuerung has contributed much to improving the built environment but little to new job creation. It is indicative of the advantages and disadvantages of reunification for rural development in the new Länder. 相似文献

Rural hollowing is a recent geographic phenomenon that has received significant attention in China, which is experiencing rapid urbanization. It has led to the wasteful use of rural land resources, and imposed obstacles on the optimization of land use and coordinated urban-rural development. Rural hollowing has various forms of manifestation, which refers to the neglect and vacancy of rural dwellings, both of which can lead to damage and ultimate abandonment of rural dwellings. Damaged dwellings have different degrees of destruction, ranging from slight, moderate to severe. The evolutive process of rural hollowing in general has five stages, i.e., emergence, growth, flourishing, stability, and decline. Based on the combination of both regional economic development level and its physiographic features, the types of rural hollowing can be categorised as urban fringe, plain agricultural region, hilly agricultural region, and agro-pastoral region. Especially, the plain agricultural region is the most typical one in rural hollowing, which shows the spatial evolution of rural hollowing as a “poached egg” pattern with a layered hollow core and solid shape. Furthermore, the driving forces behind rural hollowing are identified as the pull of cities and push of rural areas. In particular, this paper identifies contributors to rural hollowing that include rural depopulation in relation to rapid urbanisation and economic change, land ownership and land use policy, and institutional barriers. 相似文献
