A Landscape Guide in Environmental Education

Abstract

The interpretation of landscapes is an important way to learn about geography in environmental education. A Landscape Guide to the Bachelor Reserve applies geographic/historical and biological/ecological perspectives to the interpretation of ten landscape scenes along a three-mile walking tour. For each scene, the guide describes the environmental setting, the composition and structure of the vegetation, and the history of human influences. Questionnaire and field assessments document a well-received interpretive tool, and the need to guide participants across land transitions and interpret land use history clearly. Landscape guides can be used in school/community land labs and contribute to holistic learning and multidisci-plinary exercises in formal and informal environmental education programs.     

Colour infrared aerial photography as a tool for vegetation mapping and change detection in environmental studies of Nordic ecosystems: A review

The aim of the paper is to sum up knowledge of colour infrared (CIR) aerial photography as a tool for vegetation data for mapping and monitoring in environmental and biodiversity surveys and change detection surveillance. It compiles thirty years of research of the main ecosystems in Swedish vegetation, where the overall goal was to develop methods for mapping and monitoring vegetation by use of CIR aerial photographs, assess the accuracy compared to field-based mapping and to implement them as a tool in nature conservation and environmental planning. The methods include development of a classification system, identification and analysis of indicators, development of interpretation techniques, and evaluation compared to the data collected in the field. The CIR observable criteria are colour, texture, pattern, size, form, and density, based on spectral reflectance, physiognomy, life forms, ecological conditions, moisture and nutrition, vegetation period and phenology, topography, site conditions, and management methods. The methods have been used to produce vegetation maps of mountains, boreal forests, and mires in northern and central Sweden, in national inventories of wetlands, ancient meadows and pastures, key biotopes in forests and for monitoring agricultural landscapes.     

文化遗产旅游解说与翻译:评述与启示

文化独特性是文化遗产型景区的核心吸引力,了解和欣赏异质文化遗产是文化旅游者的主要动机,解说翻译是跨文化遗产旅游的桥梁。由于国内旅游规划对文化遗产旅游解说特点研究不够,景区管理者对双语解说信息创作对象不了解,导致文化遗产解说与翻译的质量影响了跨文化遗产旅游的解说教育效果,错过了通过文化遗产旅游平台对外宣传中华文化的良好机会。综述了旅游解说的概念、内涵以及有效解说和信息创作的原则,在总结文化遗产旅游特点的基础上,提出了文化遗产型景区英文解说翻译应针对国际旅游者特点的信息再创造的观点。建议文化遗产旅游景区制定针对国际旅游者消费特点的双语解说规划;旅游规划和翻译学术界应重视旅游双语解说规划和翻译的研究;翻译者在具备双语、双文化翻译能力的同时,还应该了解旅游解说和信息创作的跨学科知识。     

洞错混杂带内部结构及构造岩片组合特征

为了对洞错混杂带进行深入研究,通过遥感图像解译将其分为玄武岩岩片带、蛇绿混杂岩带和蛇绿岩带3个次级构造带,这3个次级构造带在平面上近平行延伸,向东、西方向收敛,在剖面上呈叠瓦式向南逆冲.实地检查证明,遥感解译结果符合实际情况,各带内岩块的物质组成、几何结构大不相同,中部的蛇绿混杂岩带是洞错混杂带的主带.     

板桥稀土矿遥感找矿信息提取与矿产预测研究

通过对离子吸附型稀土矿成矿规律的分析,从浙江省板桥地区的遥感地质特征研究入手,在研究区地表范围内进行稀土遥感找矿信息的提取。首先利用SPOT图像和DEM数据构建的坡度数据对与稀土成矿相关的地貌单元进行解译;然后通过光谱特征分析和基于ASTER图像的矿物遥感异常提取,获取与成矿相关的高岭土、绢云母、绿泥石等风化特征矿物的分布信息;最后叠合分析地貌、坡度及异常提取结果,进行稀土遥感找矿预测。与地质调查资料及化探数据的对比分析证实,上述方法对圈定1∶5万的大比例尺离子吸附型稀土矿分布范围是有效的,可为更详细的稀土矿产资源潜力评价提供依据。
