Abstract

A harmonious society indicates the harmonious relationship between the person and the nature. People's notion is converted from changing the nature to understanding the nature. The research of the Regional Eco-environment becomes more and more important after long-term practice of human. The digital regional planning at this stage gradually places emphasis on ecological and environmental research in order to accomplish the regional sustainable development. Rs which is the quickly updated and information-rich data sources and GIS which is the effective tool for spatial data integrating and handling plays an increasingly important role in this processing. The paper proposes integrated geographical unit as the basic analysis unit, and delivers the method and the involving elements. Geographical Unit refers to the geographical factor compounding to a certain level, the intermediate structures below the highest level. Integrated relative to the special, two or more specialty can be combined into an integrated. We accomplished two cases study with effect. The one is the research area Beibu Gulf Economic Areas of Guangxi, which lies in the South of The Guangxi Zhuang Autonomous Region of China; the other is Zhangjiajie, which is located in the northwest of Hunan province.
