Image interpretation methods, procedures for relating image pattern to ground conditions, are essential to our use of remote sensing imagery. These methods can be analyzed in respect to the role of ancillary information in the image interpretation process. In general, those procedures that are comparatively independent of ancillary information can be applied in varied geographic settings. Because almost all interpretation procedures depend to some extent upon ancillary information, a detailed and integrated knowledge of the cultural and physical landscape is a prerequisite for both manual and automated interpretation procedures. 相似文献

Abstract This article summarizes methods used in a secondary school geography class to interest students in geography through examples drawn from local geography. Instead of relying on examples taken from exotic places to illustrate geographic concepts, the local landscape is used in the classroom to teach students about geography. The article is arranged according to the six essential elements of the National Geography Standards, but it does not imply that the methods presented should be used to teach the standards. Rather, the examples presented are used throughout a course in the geography of North and South America to develop an interest among students and, with examples from the local landscape, to increase student understanding of geographic concepts related to issues presented in the course. 相似文献

Abstract Debates over the nature and extent of globalization raise many issues to be addressed in a geographic education. In this paper, I briefly review case method instruction and role-play as teaching strategies suitable for material on globalization and other geographic subject matter, and then sketch an overview of an undergraduate geography role-play that treats themes of globalization and agricultural trade. The role-play revolves around a real-world trade dispute, referred to as the Banana War, that was waged between the United States and the European Union during much of the 1990s over who could sell how many bananas to Europe. I conclude the paper by reflecting on the contributions of, limitations to and possibilities for case method instruction and role-play in geographic education. 相似文献

Abstract China, despite its failure to modernize in step with Europe's industrial revolution, has a long and rich history of commerical and economic growth, development, and integration. Economic growth and environmental change are presented here, and two dimensions—space and time—are invoked to describe the process as it took place in mainland China. The objectives are to present generalized abstractions of the Chinese earth space and environment within a chronological framework of growth and change in China. Three salient phases of progression are noted: 1) A traditional transition 2) A Western and Japanese influenced Commercial/Industrial transformation 3) A Socialist planned development At each stage of the sequence, significant landscape and environmental changes have been imposed, and these are explored in order to determine key themes and alterations at a local, regional and national scale. Such a sequential model should permit the accurate simplification and increased cross-national understanding of complex phenomena and facilitate presentation of these phenomena in classroom situations. 相似文献

In this study, we attempt to put forward a conception of landscape ecological niche, enlightened by international scholars on extending the ecological niche theory from spatial niche to functional niche. That is helpful for comprehensively appraising landscape spatial patterns and ecological functions, also, presents a new method for analyzing landscape features from multidimensional aspects. The practice process is demonstrated by taking Yan＇an region in northwestern China as a case. Firstly, the indices system including spatial attribute and functional attribute is established for assessing landscape ecological niche. Additionally, two-dimensional figures are drawn for comparing the spatio-temporal features of landscape ecological niche in 1987 and 2000 among the 13 administrative counties. The results show that from 1987 to 2000, towards Yan＇an region, spatial attribute value of landscape ecological niche changes from 1.000 to 1.178 with an obvious increment, and functional attribute value changes from 0.989 to 1.069 with a little increment, both of which enhance the regional landscape ecological niche. Towards each county, spatial attribute value of landscape ecological niche increases to different extent while functional attribute value changes dissimilarly with an increment or a decrement. 相似文献

Abstract Children love books, and through carefully chosen ones geographic concepts can be conveyed. Books are good resources—great background material for describing a place, emphasizing the culture of a region, highlighting a geographical issue, or clarifying where a place is in the world. This article explains how literature encourages geographic thinking, builds geographic skills, and develops lasting mental maps of places and regions. 相似文献

The Norwegian monitoring programme for agricultural landscapes is a sample-based programme that aims to document the current state and patterns of change in the agricultural landscape for the entire country. For this broad geographical coverage an indicator approach is the most cost-effective methodology. Landscape metrics are used as indicators in the monitoring programme based on the assumed importance of landscape composition and spatial pattern for a number of countryside interests. However, although indicators have been used successfully over a long period of time in various disciplines, their use in landscape monitoring is relatively new and there is little empirical data with which to assess their validity. This paper provides information on the performance of landscape diversity and landscape heterogeneity indices as estimated by specific biodiversity measures. Preliminary results show increasing numbers of breeding bird species and numbers of vascular plant species with increasing landscape diversity and heterogeneity, two indices that capture information on landscape content and structure. Overall, the heterogeneity index provided a better surrogate for species richness than the diversity index. 相似文献

Abstract This article deals with the issue of providing geographic training to prospective teachers from the perspective of a secondary school teacher who also teaches a social studies methods course. Research in educational journals provided a background for describing the lack of geographic training among social studies teachers. While the National Geographic Society's alliance network is addressing this issue among practicing teachers, there is still a need to include some geography training for preservice teachers. Suggestions are offered for including geography within the context of the social studies methods course. A plea is also made for geography professors to include the new National Geography Standards in their courses, especially in introductory courses. 相似文献

The apparent features of a rural landscape are the final result of the interaction among several natural and anthropic factors. The analysis of a landscape, as well as the identification of its best management strategies, can be improved when useful information about its modifications along a wide time period is available, so as to assess the effect of the transformations that have taken place there. The implementation within a geographic information system (GIS) of geographical information derived from ancient historical maps, combined with modern digital cartography and recent remote sensing images may provide a very powerful tool for a better-informed analysis and targeted decision-making strategies about the most appropriate rural landscape planning. With the purpose to detect the land use changes in a typical rural landscape in the Basilicata Region (Southern Italy), spatial analysis using free and open-source GIS tools, in which data covering a period of about two centuries, from 1829 to 2017, were implemented. This multi-temporal analysis was carried out to investigate the landscape structure transformations through the assessment of land use change and the implementation of a methodology for the identification of areas in which there has been a natural evolution of the rural landscape. Then, using landscape metrics and spatial analysis tools, some areas in which the landscape has naturally evolved without any anthropic intervention during these 188 years have been identified, and changes occurred on the rural landscape were assessed quantitatively.

Abstract This article describes the benefits of combining field-based learning within the context of a competitive setting in the geography curriculum. Findings and data are presented based on experiences gathered from teaching an upper-level university geography course that combined geographic techniques and theory into a game of capture-the-flag. Students analyzed a variety of geospatial data sources, using ArcMap Geographic Information System software, to prepare a series of maps for the game. Students reported a first-time understanding of many geographic skills that were previously ambiguous to them when the material was presented in a different format, such as lectures and labs. 相似文献

ABSTRACT Efficiency in agricultural food production has long been in focus and this has affected the spatial structure of agricultural land use. One outcome has been extensive criticism based on a wide range of negative consequences, such as for biodiversity, accessibility, cultural heritage, and aesthetics. In line with the European Landscape Convention (ELC), management of people’s everyday landscapes is important. In Norway, agricultural landscapes are the ‘everyday landscape’ for a large proportion of the population. The aim of the article is to contribute to the understanding of landscape changes perceived as positive or negative by the inhabitants. The authors focused on grain-crop dominated landscapes and the impact of smaller non-crop elements on people’s landscape preferences. They administered a photo-based questionnaire using manipulated photos to assess preferences for different agricultural landscapes. Additionally, people’s perceived objectives for the agricultural sector and agriculture’s primary functions were assessed. The results documented positive perceptions of added landscape elements and that people were both aware of and agreed on the multifunctional role of agriculture. The authors conclude that if the public’s preferences are to be taken into consideration, such as during policymaking, it is important to maintain various landscape elements in the large-scale grain field landscapes of Norway. 相似文献

Abstract The use of geographic information systems to analyze spatial dimensions of health care and disease ecology is becoming a realistic prospect for investigators in the social sciences. This review of the literature, bringing together a diverse collection of professional and academic journals, can be grouped into four categories: potential, cautionary, preliminary, and application. Enough references have been collected and reviewed to provide instructors with material for a classroom unit about 1) using GIS in a medical geography class: 2) medical applications in a GIS class; or 3) using GIS in classes which have a health and disease component. 相似文献

Eco-geographic regional system 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. In previous studies,
soil types were often taken as a basis for soil regionalization. However, the quantitative characteristics of soil indicators
are fitter than the qualitative ones of soil types for modern regionalization researches. Based on the second China’s national
soil survey data and the provincial soil resource information, by principal analysis and discriminant analysis, this paper
discusses the appropriate soil indicators as the complement of eco-geographic region indicator systems and the relationships
between these soil indicators and soil types in regionalization. The results show that five indicators are used in eco-geographic
zonality in mid-temperate zone of eastern China which are organic matter content, cation exchange capacity, pH, clay content
and bulk density in topsoils. With a regression-kriging approach, the maps of soil indicators in mid-temperate zone of eastern
China are compiled with a resolution of 1 km in every grid and the indicative meanings of these soil indicators are discussed.
By cluster analysis it is proved that these soil indicators are better than the soil types and soil regionalization in delineating
eco-geographic regions.

Abstract Justifying GIS in local government is a complex task for two main reasons: first, a GIS implementation can range from a single, well-defined application in one department to a corporate multi-purpose GIS; and, second, local authorities are complex organizations currently facing major pressures for change, and considerable uncertainty about their future structure and role. The purpose of this paper is to review the potential use of cost-benefit analysis, to explore tangible and intangible benefits, to identify the costs involved, to explore the effect that a robust GIS strategy can have on the relationship between costs and benefits, and to review some of the published material on the cost-justification of GIS in local government. 相似文献

Abstract The ultimate goal of all geographic education is to have our students think geographically for life. To this end, the five geographic skills sets allow teachers to use the inquiry approach to more accurately observe whether or not geographic thinking is actually taking place. As essential components of these geographic skills, fieldwork, journaling, and stories based on the field experience have proven to be effective tools of inquiry. This article demonstrates how a journal, kept by the author while on an advanced alliance summer institute to Russia in 1996, was used to write an original short story based on the author's fieldwork there. The author's experiences model the five geographic skills sets in developing lesson plans for the original short story, The Dragon and the Anchor. These activities allow the students to sharpen their geographic skills and develop a sense of place by studying the changes that have occurred in Russia since the fall of communism in 1991. 相似文献

Abstract Abstract. The growing interest in teaching about geographic information systems (GIS) raises a number of issues concerning the effectiveness of conventional instructional methods. To convey basic GIS concepts and applications better requires much more emphasis upon visual media. One such medium is that of VHS (or Beta) videotapes. Six currently-available GIS-oriented videotapes are reviewed for this purpose. Their contents are summarized and an evaluation is made of the usefulness of each in classroom-based GIS instruction. 相似文献

黄河三门峡至扣马段的阶地序列及成因 总被引：1，自引：0，他引：1
Based on field landscape investigations, thermoluminescence (TL), magnetostratigraphy and loess-paleosol sequence, we found
that there are at least four Yellow River terraces, whose ages are 0.86 Ma, 0.62 Ma, 0.13 Ma and 0.05 Ma, in Yuxi Fault-Uplift
(from Sanmen Gorge to Mengjin) and at least three Yellow River terraces, whose ages are 1.24 Ma, 0.25 Ma and 0.05 Ma, in Huabei
Fault Depression (from Mengjin to Kouma). All the terraces have a similar structure that several meters of paleosols directly
develop on the top of fluvial silt. It shows that the Yellow River incised and consequently abandoned floodplain converted
to terrace during the interglacial period. Therefore, there may be a link between the formation of terraces and glacial-interglacial
climatic cycles. However, the differences in the Yellow River terrace sequences and ages between Yuxi Fault-Uplift and Huabei
Fault Depression indicate that the surface uplift should play an important role in the formation of these terraces.
