Centuries of evolution of viticultural patterns in Europe have established well-known associations between cultivars and viticultural regions. Though California's viticultural landscape is much younger than Europe's, scholars increasingly talk about cultivar specialization in California wine regions. This study uses data for recent years and location quotients to test the hypothesis of regional cultivar specialization in California. Support is found for the hypothesis, though not for each cultivar and region. Evidence suggests also that there are significant differences between California and Europe with respect to viticultural specialization. Two such differences are in physical geography and wine laws. 相似文献

中国区域经济差异的时空尺度分析 总被引：136，自引：20，他引：116
运用多阶段Theil系数嵌套分解法和小波分析法,从空间尺度和时间尺度两个方面研究中国区域经济差异问题。基本结论是:从省级行政区域单元来看,东部省际之间差异的变化趋势和全国的变化趋势基本是一致的,中部和西部省际之间的差异一直相对较小,而且变化趋势较为缓慢,但是三大地带之间差异一直在增大。从地级行政区域单元来看,省内差异是全国整体差异的重要构成部分,省内差异对于全国整体差异的贡献比三大地带之间差异和省际差异的贡献显著得多。从时间尺度来看,在大时间尺度(譬如24年)水平上,中国区域经济差异的变化过程,基本上服从“倒U型”曲线规律,但是小时间尺度(譬如23年或22年)水平上来看,则呈现为一条由几个倒U与U型曲线首尾相接的“复合倒U型曲线”。 相似文献

Abstract The purpose of this paper is to examine a particular type of formal geographic region—the viticultural region—to promote an understanding of the geographical bases of wine production. The authors have found that the viticultural area is an excellent vehicle for teaching students how geographers construct and analyze regions. Although the wine industry in the United States is concentrated overwhelmingly in California and secondarily in a belt running from New York across Pennsylvania and into Ohio, most of the lower 48 states have at least one officially recognized viticultural area. The following problem has been developed to be used “as is” or to be modified for any state or region in the country. By the end of the problem, students have gained hands-on experience in defining regions, correlating physical geography with human activities, and thinking about the importance of place names and scale. 相似文献

中国区域发展格局演变过程与调控 总被引：6，自引：4，他引：2
2018年底中国人均GDP达到64520元（将近10000美元）。世界各国发展历程和区域发展差距倒“U”字型曲线表明,中国区域发展格局演变将步入从区域间经济发展差距持续扩大转向缩小的拐点区段。本文讨论了1978年以来拐点发生前40年间中国区域发展格局演变过程,① 处于发展上游（前8位最发达的省区）和下游（后8位欠发达省区）省区人均GDP的差距从1978年的407元增加到2018年的53817元;② 城市化和经济发展的重心在外向型经济、非公有经济的拉动下,呈顺时针方向发生旋转,中国东南地区成为经济加速集聚的区域;③ 中国区域发展格局形成以京津冀、长三角、珠三角、成渝地区四大核心区域为顶点、相邻区域的连线为边界合围成的菱形结构,其GDP占全国比重稳定在75%左右。2020年中国区域发展格局应进入演变的拐点,一方面表现为区域经济差距的缩小,另一方面则是从非高质量的区域发展向高质量区域发展的转变。区域高质量发展是在经济效益持续增长过程中,生态效益和社会效益将相向基本同步的增长过程,并呈现出因地域功能不同而分异的区域高质量发展模式。未来30年,按照促进区域均衡（协调）发展和高质量发展的双重目标要求,应把重点城市化地区、相对欠发达地区、重要安全保障区等三类区域以及区域间互动关系等为调控和优化中国区域发展格局的重点,而建立以主体功能区划—战略—规划—制度为统领的空间治理体系,将成为调控和优化区域发展格局的基本保障。 相似文献

Regional dynamics in the globalising wine industry: the case of Marlborough, New Zealand 总被引：1，自引：0，他引：1
The rapid expansion of the New Zealand wine industry has rested largely on a specific wine commodity form, Marlborough Sauvignon Blanc. Global demand for a specialised product has provided the impetus for substantial development at the regional level, an increasingly complex industry structure, and for the intrusion of international capital. This paper explores the contests and relations within the industry through attention to the commodity's value-added chain, wherein recent developments are interpreted as a contest over the brand rents. The contemporary situation therefore may be explained through overlapping organisational and geographic framings of these relations: producer versus buyer-driven dynamics; regional–national and global interests; and inter- and intra-corporate strategies. The commercial contest for control of the region-varietal commodity reveals some paradoxical outcomes in which the region is reaffirmed as a site of investment in an evidently globalised industry, and the significance of who controls what fraction of the value chain is re-asserted. 相似文献

The investigation of L g attenuation characteristics in the region bounding the western branch of the East African rift system using digital recordings from a seismic network located along the rift between Lake Rukwa and Lake Malawi is reported. A set of 24 recordings of L g waves from 12 regional earthquakes has been used for the determination of anelastic attenuation, Q Lg , and regional body-wave magnitude, m b Lg , scale. The events used have body-wave magnitudes, m b , between 4.6 and 5.5, which have been determined teleseismically and listed in ISC bulletins. The data were time-domain displacement amplitudes measured at 10 different frequencies (0.7–5.0 Hz). Q Lg and its frequency dependence, η , in the region can be represented in the form Q Lg = (186.2 ± 6.5) f (0.78±0.05) . This model is in agreement with models established in other active tectonic regions. The L g -wave-based magnitude formula for the region is given by m b Lg = log A + (3.76 ± 0.38) log D − (5.72 ± 1.06), where A is a half-peak-to-peak maximum amplitude of the 1 s L g wave amplitude in microns and D is the epicentral distance in kilometres. Magnitude results for the 12 regional earthquakes tested are in good agreement with the ISC body-wave magnitude scale. 相似文献

Eco-geographic regionalization has been one of the most important topics in China's regionalization researches since the end of the 20th century. It is a major ecosystem in geographic zonality. A hierarchical system, which is formed by division or combination of natural features based on geographic relativity and comparison of major ecosystem factors (including biological and non-biological) and geographic zonality, is called eco-geographic regional system. This paper introduces process of China's regionalization development. The first level unit, temperature zone, is delineated with main criteria of temperature. The second level unit, humidity region, is based on criteria of water/moisture states. The third level unit, natural region, is divided according to medium geomorphologic units. Vegetation types and soils are applied as supplementary criteria to indicate temperature and water/moisture states. Mapping process from qualitative to quantitative and China's eco-geographic regional system are also explained in this paper. 相似文献

关联视角下的区域产业动态研究进展与反思 总被引：3，自引：1，他引：2
区域产业动态是经济地理学的经典研究主题。不同尺度的传统经济地理研究常以企业、产业和区域为研究对象,忽略了不同个体之间的关联。近年来,经济地理学增加了关于企业关联的研究,但对于产业关联和区域关联的关注仍显不足。基于关联视角,本文首先围绕产业关联和区域关联等概念探讨了关联的形成机制,进一步梳理关于产业关联、区域关联与区域产业动态的研究进展,并为未来区域产业动态研究提出相关建议。与企业关联相同,产业和区域关联也与个体间的要素流动有关。现有研究表明产业关联有助于揭示区域产业演化规律,而区域关联会通过区域间要素流动影响区域产业动态。关联视角是区域产业动态研究的新视角,具有较大的研究潜力,值得引起经济地理学者们的关注。 相似文献

Regional tourism and South-South economic cooperation 总被引：1，自引：0，他引：1
Krishna B. Ghimire 《The Geographical journal》2000,167(2):99-110
Regional tourism within developing countries is a growing phenomenon. Yet this aspect has been largely neglected in social science research as well as tourism planning. This paper highlights the general nature, scale and economic significance of regional tourism in three leading regions in Asia, Africa and Latin America. The topic is especially timely as economic self-reliance and cooperation are increasingly reiterated in the context of the emergence of regional groupings. A key question addressed is whether regional tourism development represents any new and viable prospects for regional economic improvement and partnership, especially compared to international tourism centred on attracting visitors from industrialized countries. Based on a critical assessment of the experiences of three regional blocs (ASEAN – the Association of South-East Asian Nations; SADC – the Southern African Development Community; and Mercosur – a common market comprising Argentina, Brazil, Paraguay and Uruguay, with Chile being an associated member), the paper suggests that a basic appreciation of the prospects of regional tourism is not enough to produce perceptible benefits. Regional tourism development is occurring in a haphazard manner, with little attention to managing existing socio-economic inequalities and centre-periphery relations. The paper is based primarily on the review of secondary literature readily available to the author combined with a few documents obtained directly from different regional organizations or through Internet search. A small amount of material, especially concerning emerging tourism trends and outcomes, is drawn from a research project on national mass tourism in developing countries coordinated by the author at the United Nations Research Institute for Social Development, Geneva. 相似文献

基于ESDA的区域经济空间差异分析——以江苏省为例 总被引：79，自引：10，他引：79
基于ESDA全局和局部空间自相关分析,利用江苏省1978～2002年县域人均GDP数据,对江苏省县域总体和局部空间差异的变化趋势、特征与成因进行了初步探索。结果首先表明,随着我国改革开放进程的逐步深化,江苏省县域经济空间差异在总体上呈现缩小趋势。其次,江苏省县域局部空间差异不断缩小,特别是苏南和苏北县域,表现出与周边地区同步发展态势。再者,苏南地区对全省的极化效应明显大于其扩散效应。大致自1992年以来,苏南和苏北地区内部分别形成了与周边地区显著相似的区域。最后,江苏省县域总体和局部空间差异的缩小并不是全省区域经济协调发展的标志,而是南北空间分异的表现。在循环累积因果机制作用下,南北差异有可能进一步扩大。 相似文献
