锗是典型的分散元素，是除硅以外最重要的半导体材料，在红外光学、光纤通信、化学催化剂、太阳 能电池、生物医学、电子器件等各领域都有广泛的应用。地球上锗资源较贫乏，我国的锗储量居世界第一位。 云南省锗储量占全国储量的40％左右，并拥有红外光学技术研发的基础，对我国锗产业具有十分重要的意 义。文章具体分析了云南省锗产业发展的外部和内部环境，提出了云南省2006～2020年锗产业发展的方向 和总体目标，探讨了锗产业链、产品定位、产业布局、重点发展的项目和支撑体系。

Germanium is a typical dispersed element, it is the most important semiconductor material except for silicon. Today, Germanium is used principally in the field of infrared optical, telecommunication fiber optics, a polymerization catalyst for polyethylene terephthalate(PET), a kind of commercially important plastic in solar cell and in biomedicine, and as a semiconductor and substrate in electronics circuitry. Germanium resource is scarce in the earth.  The reserve of germanium in China ranks first in the world. Yunnan Province owns about40percent of germanium reserve of China and owns the basis of research and development in the field of infrared optical, so it is very significant to develop germanium industry in Yunnan. This paper analyzes the exterior and interior circumstances for the industrial development of germanium in Yunnan, brings forward the orientation of development and the total target of Yunnan germanium industry from2006to2020, and discusses the industrial chains of germanium, product position, industrial layout, the supporting system and the key projects.
