编制中国76种元素地球化学图将使我们首次了解元素周期表上除氢、氧及惰性气体之外所有元素在中国大陆表层的分布,川滇黔桂76种元素地球化学图的编制是这一研究项目的试点。本文以不同实验室取得的Ag、Cs、Ga、Ge分析数据为例,探索、衡量不同实验室地球化学图相似性的方法,以优选实验室进行川滇黔桂4省区约4000件组合样76种元素的大规模分析工作。  相似文献   

A Landscape Guide in Environmental Education     

《The Journal of geography》2012,111(2):69-77

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.  相似文献
