The future of geography     

Nigel Thrift 《Geoforum》2002,33(3):291-298

This paper is an attempt to assess the current state and future prospects of Geography especially but not only in Britain. It is quasi-polemical and should be read in that spirit. The paper looks first at the notable successes of physical and human geography. It then considers how these successes are being buttressed by current events taking place in the world. Next, the paper considers the main problems that beset geography. Finally, however, the paper ends on another positive note by considering some of the exciting new developments that are now taking place in the discipline which will allow it to relate to more of the many worlds that make up geography's vocation.  相似文献

Regulating Land Use Conflict on the Urban Fringe: Two contrasting case studies from the Australian poultry industry     

STEVEN HENDERSON 《The Australian geographer》2003,34(1):3-17

Land use conflict involving farm externalities represents an increasing policy concern in Australia as agricultural activities intensify and as the nation's metropolitan areas continue to expand outwards. A review of the rural-urban fringe literature reveals a noticeable absence of research exploring the intensity of conflict experienced by farmers. Similarly, inadequate attention has been given to the policies adopted by government to manage conflict. This article contrasts the regulatory system that has been implemented to manage conflict involving poultry farming on the metropolitan fringe of two Australian state capitals: Perth, Western Australia and Sydney, New South Wales. Spatial variation in the nature of government intervention is uncovered. In the discussion that follows reasons are identified to help explain such variation including state ideology, metropolitan growth, industry activism, geographical constraints and farm characteristics. It is concluded that where agricultural industries experience internal political divisions and a geographically dispersed membership it becomes more difficult to influence government policy.  相似文献   

Productivity Profiles of PhD-Granting Geography Departments in the Unites States: 1980–1994     

Richard E. Groop  Randall J. Schaetzl 《The Professional geographer》1997,49(4):451-464

In our study, 48 U.S. departments that grant geography PhDs are compared along four measures of academic productivity. Using 1980–1994 as the base period, research productivity of faculty was assessed by counting book titles, as well as authorships in 77 journals. Teaching productivity was determined by placement of PhDs in graduate programs of geography in North America, and by a weighted index of teaching outcomes. Data were summed for departments, but are reported primarily as productivity per person (per FTE count). The results point to a wide variety of departmental profiles, from those departments that appear to emphasize teaching outcomes to those that are more productive in book publishing and journal authorship, with several exhibiting a balance between teaching and research.  相似文献   

The Geography of Personal Name Forms     

Edward Callary 《The Professional geographer》1997,49(4):494-500

The geographic distribution of formal and informal names is considered. Given names are variable and bearers may identify themselves with one name form or another (e.g., William, Will, Billy, Bill, W. T., “Skip”). The form of name chosen by state legislators was classified as formal or informal and the proportions of each were plotted by state. Three regions are identified by their relative use of name formality: the Northeast, where formal names are the rule, the South, centering on Arkansas, where informal names are common, and the West, also characterized by informal names. The West is divided between the Mountain and Pacific states, with large numbers of informal names and the states which they surround, which tend toward formal names. Some states, especially those of the Midwest, do not participate in this process. Indiana and South Carolina are exceptions to the general patterns. Informal names presume to create solidarity between legislators and voters. The South and West are apparently less formal than the Northeast in general, also in name usage.  相似文献

Conservation tillage and input use   总被引：1，自引：0，他引：1  

N. D. Uri 《Environmental Geology》1997,29(3-4):188-201

 There continues to be a question as to the overall effectiveness of conservation tillage practices in reducing the impact of agricultural production on the environment. While it is generally recognized that water runoff and soil erosion will decline further, as tillage and mulch tillage systems are not used more extensively on cropland, what will happen to pesticide and fertilizer use remains uncertain. To gain some insight into this, the conservation tillage adoption decision is modelled. On the assumption that the decision to adopt conservation tillage is a two-step procedure, the first decision is whether or not to adopt a conservation tillage production system and the second concerns the extent to which conservation tillage should be used – appropriate models of the Cragg and Heckman (dominance) type are estimated. Based on farm-level data on corn production in the United States for 1987, the profile of a farm on which conservation tillage was adopted is that the cropland had above-average slope and experienced above-average rainfall, the farm was a cash grain enterprise, and it had an above-average expenditure on pesticides and a below-average expenditure on fuel and custom pesticide applications. Additionally, for a farm adopting a no-tillage production practice, an above-average expenditure was made on fertilizer. Received: 18 September 1995 · Accepted: 6 December 1995  相似文献   

The GIS and analysis of earthquake damage distribution of the 1303 Hongtong M=8 earthquake     

GAO  Meng-tan 《地震学报(英文版)》2004,17(4):398-404

The geography information system of the 1303 Hongton M=8 earthquake has been established. Using the spatial analysis function of GIS, the spatial distribution characteristics of damage and isoseismal of the earthquake are studies. By comparing with the standard earthquake intensity attenuation relationship, the abnormal damage distribution of the earthquake is found, so the relationship of the abnormal distribution with tectonics, site condition and basin are analyzed. In this paper, the influence on the ground motion generated by earthquake source and the underground structures near source also are studied. The influence on seismic zonation, anti-earthquake design, earthquake prediction and earthquake emergency responding produced by the abnormal density distribution are discussed. Foundation item: National important fundamental research “The Basic Research of Important Project in Damage Environment” and The important project “The Seismic Hazard Assessment Research and Anti-earthquake Structure Research” from China Earthquake Administration during the 10th Five-year Plan.

基于RS和GIS的农业土地利用污染分析   总被引：1，自引：0，他引：1  

姜馨  吴健平  石纯 《现代测绘》2004,27(3):12-14

农业已被确认为地表和地下水最主要的非点源污染源，而土地利用方式又是影响非点源污染的关键性因素。大规模的土地利用与开发、化肥与农药用量的增加、规模养殖业的发展、生活垃圾的增加等，这些非点污染源严重威胁水体质量，进而影响到人们的生活。为了更好地预测和控制、管理非点源污染，必须研究其负荷定量化问题。本文从以上几方面入手，讨论了非点源污染与农业土地利用方式之间的关系，利用组件GIS技术，以网格为评价单元，实现非点源污染负荷的定量计算及可视化分析。文章最后以上海市松江区作为研究区域，对该区的污染情况进行了分析。  相似文献
