经线、纬线、赤道等概念是自然地理中的基础性概念,有关相对空间位置确定或变化的地理问题,不论是定性分析还是定量计算,往往都会涉及这些概念的内涵。对比中学地理教材和网上搜索的内容可以发现,教材与“360百科”对这些概念的定义是不一样的。笔者以为,教材和网络对赤道的定义,以及教材对经线、纬线等概念的定义都有值得商榷的地方。为便于分析,我们将教材及“360百科”对这些概念的定义分别摘录如下:在地球仪上,与南、北极距离相等的大圆圈,叫赤道。所有与赤道平行的圆圈叫纬线。[七年级《地理》(人教版·上册)第6页,2012年版]
The concept of meridian, latitude and equator is the basic concept in natural geography. The geographical problem of determining or changing relative spatial position often involves the connotation of these concepts, whether qualitative analysis or quantitative calculation. Comparison of geography textbooks and online search content can be found, textbooks and “360 Wikipedia ” The definition of these concepts is not the same. The author believes that the definition of equator in teaching materials and network and the definition of concepts such as warp and weft in teaching materials are both debatable. In order to facilitate the analysis, we will textbook and “360 Encyclopedia” The definition of these concepts were extracted as follows: On the globe, and the South Pole, equal distance circle, called the equator. All circles parallel to the equator are called wefts. [Seventh grade “geography” (PEP · the first volume) page 6, 2012 edition]
