The Research of Geological Hazards Warning and Forecast System Based on Rainfall Model

This paper is according to the illustration of intensity of rainfall--duration of rainfall and the critical precipitation theory which refers to the relationship between rainfall and the happening of landslides, taking the main types, scale, time and spatial distribution and the actual extent of damage of geologic hazards in Hubei province into consideration, establishing a critical precipitation and early warning and forecast criterion model of regional geologic hazards based on the research on the relationship between rainfall and the spatial distribution, coming up with a solution of early warning and forecast system of geologic hazards, which is on the base of Internet web or communication, WebGIS (MapGIS IMS), and the architecture of SQL Server and its relative Operating Systems.
