According to the analysis of remotely sensed data and other multi-information of study area (its longitude: 113.5°-117° and latitude 39.5°-42°), the authors dynamically evolved desertification of Beijing and its neighboring areas, which the images were used in three different periods, 1987 TM, 1996 TM and the CB-1s CCD 4, 3, 2 bands of 2000, 4 orbits and 16 (CBERS-1) scenes (the resolution is 19.5m). By synthetically analysis, we obtained the area desertification distribute and evaluated space-time information. Based on the remote sensing interpretation and database of desertification multi-information efficiency distilled from geology, hydrography, anthropogeography, agrotype, vegetation and so on, we build up desertification dynamic simulation model with CA (Cellular Automata) theory and GIS (Geographic Information System) tool. Then utilizes this model to predict desertification development of Beijing and its neighboring areas. The result of the experiment proves that the model is effective to simulate desertification development in terms of macroscopic and microcosmic. The desertification of Beijing and its neighboring areas develop from west to the east, the southern edge is 72km to Beijing city where lies in the north of Jundu mountain crossing Yanshan with Taihang mountains, which prevents the development of desertification.
Through the physical experiment simulation of the lineaments on the surface, the paper reveals the mechanism and genesis of the indirect display caused by buried geological anomaly. A view that RS image can show the character of buried geological anomaly is put forward in the paper. In order to prove the view, a physical model which includes basement and cover is established. Firstly, it makes an analysis of model and expounds the condition for simulation. Secondly, it describes the process of simulation and its results. The model is mainly designed to measure the deformation of its cover, which includes two stages. During the first stage, three-dimension stress field of cover itself mainly controls the deformation. During the second stage, the deformation of cover is mainly controlled by the activity style of the buried structure. The development character of this stage is quite incompatible. Finally, it concludes that the track of deformation crack composed by surface lineaments and those information quite incompatible with background character are very likely the indirect display of buried geological anomaly. So the selection of this information is very important for revealing the creation and genesis of buried geological anomaly.
