Abstract : With Qinghai-Tibet Plateau as the study area, this zonal environmental and geological integrated appraisement
system based on RS data is mainly composed of three kinds of integrated appraisement models, i.e., Overlay Computing,
Analytic Hierarchy Process (AHP) and Fuzzy Gray Multi-method. There are three parts of components in this appraisement
system, which are modal running platform, modal spatial system and modal attribute system. With this appraisement system,
different models could be used to evaluate environmental and geological status of the same place, and the appraisement
results from different models could be analyzed separately and compared with each other. In addition, the system solves the
data conversion problem for different data types and the cartographic problem in the printing process of the appraisement
result. With this appraisement system, the researchers needn’t to open both GIS (Geographic Information System) and RS
(Remote Sensing) software at the same time to operate spatial data such as ArcGIS and ERDAS. With the adoption of Overlay
Computing Method and Fuzzy Gray Multi-method, the appraisement system selected five kinds of indexes, namely Disaster,
Hungriness, Marsh, Glacier and Fault, in the Qinghai-Tibet Plateau to evaluate local environmental and geological status.
It is proved that the appraisement result is well consistent with the field survey data.
