Abstract
Mud-rock flow and landslip often happen on the east side of Qinghai-Xizang Plateau, and the severe precipitation is the main cause of the mud-rock flow and landslip events. Because the distribution of surface rainfall station on the east side of Qinghai-Xizang Plateau is only a few and lack of representation, so it is hard to determine the rainfall for any one of region. But the radar can estimate intensity of precipitation in radar scanning region, it is a way to monitoring the disaster areas where mud-rock flow and landslip often happens. The radar system monitoring of mud-rock flow and landslip over the east of Qinghai-Xizang Plateau has been established through the non-uniform handling technique of different radar parameters, the automatic display of positions and informations of the main stations and mud-rock flow and landslip areas, and contrast analysis of radar echo data at present with automatic record informations in database and so on. The system can estimate precipitation and early signs of the disaster from various angles, which changed the earlier way of depending on subjective judgement mostly. The system raise not only the accuracy of the short time forecast, but also the automatic level of forecast way degree. It can work better with other forecast methods to prevent disasters. However, the system has run just a short period, and should be perfected in practical work in the future.
