云南糯扎渡自然保护区鸟类三维专题图制作研究

Three-dimensional Mapping of Birds in Nuozhadu Nature Reservation Zone of Yunnan

大多数自然要素和现象都是呈三维空间分布的,但由于受技术手段的限制,分布在三维空间上的这些自然要素和现象,只能在二维空间上进行描述和表达。为了实现自然保护区真实世界的三维立体展示,结合糯扎渡自然保护区综合科学考察,利用其数字高程模型以及植被、鸟类专题调查数据,使用ArcView、ArcMap、ERDAS等软件,进行了该保护区三维立体鸟类分布图的制作研究。通过研究,实现了从二维平面专题图向三维立体专题图的跨越,并且在图上用彩色鸟标注鸟种的分布现状,增强了自然保护区综合科学考察成果的形象性、生动性、可视性和实用性。该研究成果对制作其他三维立体专题图也具有一定的参考价值。

Most nature elements and objects are three dimensional, but they are quite often expressed in two dimensions due to technical limitation. The study was to develop a three D-map of bird species in Nuozhadu Nature Reservation Zone with an digital elevation model and data of the vegetation and the bird species obtained from comprehensive science surveys for the nature reservation with aids of software like ArcView, ArcMap, ERDAS etc. The study helped to replace two-dimensional maps with three-dimensional ones,and birds were marked on their habitats with colorful mark.Therefore a map as output from the comprehensive science survey was made with more visualized, more interesting and more practicable.The study was of remarkable reference value for other similar three D mapping.
