Based On 3s Technology Landslide Prediction System For Study

Because of the complexity, diversity and variational randomicity of landslide's geological process,formative condition and inducement elements, dynamic monitoring information of the landslide is captured very difficultly. Especially due to the juvenility of the dynamic inspecting technique and its imperfect basic theory, the landslide time-forecast is always a very difficult and hot problem today. In this paper, GIS, RS and GPS are put into landslide time-forecast system. By this, the author want to create an economic and practical landslide time-forecast system. Then the landslide time forecast will be more scientific ,veracious and processing.In this paper the status quo and developing trend that the landslide time- forecast and 3S technique are applied in landslide study is presented. At the same time the particular superority and function of 3S technique in landslide early inspection ,monitoring and forecast are analyzed.Based on the analysis of distortion and destroy mechanism of landslide, taking the character of landslide system into account, and starting from the basic problem of landslide time-forecast system, the landslide time-forecast system is thorough systematically studied and the landslide time forecast system and flow are created. Landslide inspecting net based on 3S technique is created too. The structure of inspecting net and the measure of immediate monitoring methods are discussed at the same time.According to theory and measure of the above mentioned, the database design, the global structure design, interface design and function module design for landslide GIS system are carried through in this paper. Landslide data is discussed thoroughly from data type, data structure and its character etc. The main technical problem in the process of system exploitation is resolved.The paper will give reference to subsystems' exploitation and connect.
