A technique for measuring total resource potential is proposed. For a selected set of resources (coal, oil and gas, iron ore, hydro power, timber, arable land, forage land), reserves are divided by the estimated period of use to obtain annual productivity. The resources are then valued in terms of a set of unit prices. The inclusion of agricultural land resources tends to assign a greater role to the Western portions of the USSR than is normally the case in resource estimates. The significance of the mineral-rich Eastern regions is also understated by limiting reserve estimates to those that are likely to be accessible in the foreseeable future (10 to 15 years). Resource density per unit area shows particularly high values for the southern agricultural regions, especially where they are combined with significant mineral and hydro resources. Resource availability per 1000 population shows expectedly high values for the sparsely populated Eastern regions of the USSR.  相似文献

The exploitation of natural populations of red deer forms an important land use in large areas of the Scottish Highlands, especially the highest and most rugged parts of the region. Despite its areal significance red deer land use has been the subject of very little geographical investigation.

The ecology of red deer is an important factor in the Highland land use situation, and environmental controls on the characteristics of the red deer resource are strong. Wide spatial variations exist both in deer population densities and in stag weights. Considerable difficulties arise in regard to the availability of comprehensive population and weight data, but despite these difficulties certain areas, particularly in the borderlands between Inverness‐shire and Ross‐shire, stand out as the most productive deer areas.  相似文献

The faunal assemblages from Asnæs Havnemark, Fårevejle and Trustrup, located in northwest Zealand, Denmark, yielded extensive yet substantially fragmented bone material dating predominantly to the late Mesolithic Ertebølle culture, ca. 5400–3950 cal BC . This paper presents a combined assessment of skeletal part representation of red deer (Cervus elaphus) and roe deer (Capreolus capreolus) from these three sites in conjunction with quantification of overall fragmentation data for the assemblages. These data indicate that the observed pattern of skeletal part abundance is most consistent with a pattern of density‐mediated skeletal attrition, and therefore the whole carcasses were initially deposited. Deer were not part of a logistic exploitation strategy at these sites. This indicates variability during the Ertebølle period not only in which resources were exploited, but in how these resources were processed. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

中国目前已进入新型工业化和城镇化转型发展的新阶段。尽管如此,土地资源特别是城市建设用地的供给与需求之间矛盾仍然很突出,土地集约利用问题也一直是影响城市经济社会可持续发展的关键因素之一。目前,土地集约利用评价一般集中在宏观和中观尺度,难以反映各微观经济主体土地利用状况等深层次问题。本文以张家港市为例,从微观层面对市域范围内规模以上工业企业用地集约性进行评价,提出基于企业综合效益的土地集约利用评价体系,并借助ArcGIS工具进行空间匹配,为更清晰地理解和判断城市土地集约使用状况,指导城市工业布局优化、土地利用效率提高提供了一种新的方法。  相似文献

Drought, increased population, war, air pollution, climate change, industrial and agricultural production, sanctions, inefficient water and natural resource use, and lack of enforcement of existing environmental regulations have contributed to Iran’s current environmental crisis. Insufficient water resources are forcing people to migrate, putting pressure on others. Aquifers are being drained. Air pollution has made living conditions in Iran’s cities increasingly challenging. Wind erosion is furthering the desertification of agricultural land, creating greater production demand on remaining arable areas. Biodiversity is under threat. On the other hand, Iran’s environmental future can be positively influenced by the collaboration of the public, private and non-profit sectors. Awareness and education, along with greater financial and human resources, will be necessary to tackle the problem.  相似文献

It is surprising that despite all the pleas and policies regarding the development of sustainable land use systems, there is still considerable ignorance regarding the nature and significance of land resources. This paper traces the development and achievements of land evaluation during the 20th century, with particular reference to soils. The most active period was between 1950 and around 1980 with the development of soil and land capability surveys, methodological advances initiated with the FAO Framework for Land Evaluation, and regional land resource assessments. Thus there were considerable achievements in land evaluation by the early 1980s, and subsequently there have been important advances in the subject through the application of GIS, spatial analysis, modelling and fuzzy set algebra. Since the late 1990s there has been a phenomenal rise in interest in soil quality assessment. Considerable debate has focussed on definition, and methods of assessment and monitoring. The latter part of this paper discusses the major challenges to the development and application of land evaluation. The inadequacy of much soil survey data in terms of variables, quality, spatial coverage and scale is emphasised. Also, there is a continuing need to highlight the centrality of land resource issues in any attempt to develop sustainable land use systems.  相似文献

西安市相对资源承载力与可持续发展研究   总被引:10,自引:0,他引:10  
以全国和陕西省为参照区域,分别计算了1978、1980、1985年和1990-2002年间各年西安市自然资源、经济资源的相对承载力和综合承载力,同时分析了它们的动态变化过程。指出西安市由于人口增长、经济发展与资源利用的不协调,导致其综合承载力长期处于超载状态,而且近年来由于水、土资源的大规模开发利用,使超载状态愈趋加重。因此,西安市的可持续发展应采取合理控制自然资源开发规模、大力发展经济、控制人口增长等措施,不断协调人口、资源、环境和发展的矛盾,逐步走向可持续发展。  相似文献

The Cherokee Removal Cases — Cherokee Nation v. Georgia 1 and Worcester v. Georgia 2 —stand as the dramatic last act of the Marshall Court era. Thomas Jefferson was long dead by the time of the removal of the American Indians from the land north and south of the Ohio River. Yet in many ways the Cherokee Removal Cases that bedeviled Marshall in his final years on the Court were Jefferson's revenge, the first bitter fruits of policies adopted during his presidency that created the political and legal environment for the Indian Removal Act of 1830 and the Cherokee Nation litigation itself. This Jeffersonian legacy is ironic, given that Jefferson as a scholar, diplomat, and Secretary of State was an ardent supporter of Indian sovereignty and eventual citizenship. Yet these views were subordinated during his presidency to concerns of what we would term "national security," to preserve the Union, and to advance the interests and needs of his political party.  相似文献

The Richards site is attributed to the Philo phase of the Fort Ancient tradition of the Ohio Valley area. Human skeletal material from the site shows evidence of peri‐ and post‐mortem taphonomic changes, including cut marks, burning and fracturing. Previous analyses have discussed explanations for these changes, including secondary burial, ritual destruction and cannibalism. Researchers have theorised that, allowing for differences in anatomy among species, humans and animals butchered for the same purpose (consumption) will show similar patterns of taphonomic changes associated with butchery. The human remains at the Richards Site were disposed in general midden pits containing mixed cultural debris and faunal remains. White‐tailed deer (Odocoileus virginianus) constitutes approximately 60% of all the faunal bone, indicating that it was a major food resource. To test a cannibalism explanation, a comparative analysis of human‐induced taphonomy in human and deer skeletal remains was performed, using chi‐square and odds ratio tests. If humans were being used as a food resource, the pattern of butchery seen would mirror that of the deer. The analysis described here compares the patterns of treatment and disposal of human and deer skeletal elements at the Richards site, to test whether both species were used as food resources. Similar types of evidence for human‐induced taphonomic changes, including cutting, chopping, burning and breakage, can be seen in both species. However, results indicate that, in general, human remains show much more evidence of perimortem treatment than do deer remains. In fact, the common odds ratio for perimortem treatment in all bones is 3.25, indicating that a human bone is 3.25 times as likely as a deer bone to be affected by burning, cutting or chopping. This probably indicates that perimortem treatment of humans was greater than that necessary simply for butchering for consumption. Copyright © 2005 John Wiley & Sons, Ltd.  相似文献

The Uyuni salt flat in Bolivia is a strategic location with a vast deposit of lithium; a key mineral for the production of Li-ion batteries for electric vehicles and energy storage. Over time, the Uyuni salt flat has become a space of contestation and grievances over its mineral resources, its territorial limits and for the most ambitious State-led project for lithium extraction and industrialization in Bolivian history. The paper aims to interrogate how notions of space ownership are intertwined with the governance of strategic resources such as lithium. Using qualitative primary data collected in Bolivia between 2014 and 2017, I explore the case of the Uyuni salt flat and the territorial arrangements of the nearby region (southwest region also known as the Land of Lipez). By examining the geo-spatial history, this case, I argue, illustrates geo-spatial delimitations are inherently political, contested and co-produced by the surrounding communities to define forms of access to and control of resources and the territory. The co-production of territory and the governance of its resources produces new spatial and political configurations in which there is a growing tension in terms of the recognition of indigenous land rights in spaces where the extractive frontier is expanding and the State maintains and perpetuates power imbalances in the sphere of decision-making. As this case shows, the history, the struggles over the governance of its resources and the land titling process behind reveal a territorial project in constant making and entangled in a political project to control mining of lithium in Bolivia.  相似文献

The constructs of ‘territory’ and ‘terrain’ are the subject of increasing scrutiny within political geography. While momentum builds in their interrogation as both diverse and lively practices, and complex political technologies, this article takes pause. Drawing on a rich and diverse range of feminist scholarship, it seeks to reflect upon existing trajectories and provide provocation for further accounting. Inspired throughout by, and seeking to bring to bear, a feminist perspective on territory and terrain, this article follows a tripartite structure. First, it critically explores the bodies of knowledge historically underpinning the concepts of territory and terrain. Developing a call for a feminist historiography of territory and terrain, we reflect upon both the gendered evolution of the concepts, and their ongoing reproduction in conceptual debates. Second, it seeks to both highlight and diversify embodied accounts and accountings of these concepts. Here, thinking with and beyond the body, we turn to the non-human and spiritual to explore territory and terrain in expanded and extended ways. Lastly, we examine bodies of expertise, reflecting on academic territories and terrains, and highlighting potential concepts and methodologies seeking to (re-)sculpt and (re-)articulate understandings of territory and terrain. The paper, whilst not all-encompassing, serves as an important provocation that seeks more equitable accounts of political geography's messy, muddy, and lively territories and terrains.  相似文献
