Digital Environment Model Study Based on GIS
基于地理信息系统的数字环境模型研究

This paper shows a new idea of establishing the digital environment model using remote sensing and GIS techniques. We used order numerical array for building the digital environment model,and quantitatively assessed the ecological environment situation of central Tibet.It focuses on model building and method realization. First, an idea of digital environment mode has been suggested Then, how to use this model to establish environmental monitoring and environmental quality assessment has been fourth discussed.
