本文介绍的模型与过去的沙盘模型相比,有本质的差别。它是用地形图制成立体地形图,缩微后的地形地貌有逼真的感觉,既可明察小地形,又可纵览宏观地形地貌。中南林学院为了适应现代化教学的需要,校方委托了本文作者,设计并制作了湖南省大围山林场教学模型(见图,可惜,本刊只能登黑白照片,影响了效果),校方十分满意,据反映:制作工艺合理,速度快,成本低,效果好。本刊特刊登介绍立体模型的特点、作用的短文,以引起大家的兴趣,如您单位工作需要,请迳直与作者联系(合肥安徽省林业厅张树贤邮编230001)。
The model presented in this article is essentially different from the sand table model of the past. It is made of topographic map with three-dimensional topography, microfilmed topography has a realistic feeling, both small terrain observation, but also an overview of the macro-topography. In order to meet the needs of modern teaching, the School commissioned the author and designed and produced the teaching model of Daweishan Forest Farm in Hunan Province (see the figure, unfortunately, this magazine can only get black-and-white photos, which has an effect on the results). The school is very satisfied, It reflects: production process is reasonable, fast, low cost, good effect. This issue of special publication describes the characteristics of the three-dimensional model, the role of the essay in order to arouse your interest, such as your work unit, please direct contact with the author (Hefei Anhui Forestry Zhang Shixian 230001).
