Research & Implementation Of The Mountain Flood Disaster Monitoring And Warning System Based Webgis

China is in the East Asian monsoon region, the hills rainstorm is frequency, because of the terrain and complex geological conditions and human activities, leading to frequent mountain flood disasters, even the other geological disasters such as mudslides and landslides. It is difficult to prevent because it is suddenly, strongly and quickly.Non-engineering measures of the mountain flood prevention as the focus starts late. In order to explore the local conditions around the mountain flood prevention way and method, protecting the safety of hilly people and reduce disaster losses, the views of the State Council approved the request to the county administrative serious flood disasters as a unit, pilot mountain flood prevention should be conducted and it is very necessary and urgent.This article firstly analyzes the defence of mountain flood disaster, and then analyzes the WEBGIS key parts and its develop structure, according to the characteristics of the system requirements, analyzes the architecture of mountain flood disaster monitor and early warning system. and achieves the key technologies of the system.Construction of flood disasters monitoring and early warning system is an important non-engineering measures mountain flood prevention, the system will improve the construction of storm mountain flood disasters to share data transmission, monitoring information, early warning analysis and processing timeliness and accuracy, improve mountain flood defense command and decision science, more fully play the early warning system engineering benefits of disaster reduction.In this paper, a ZTE-V Information Technology Co., Ltd. self-developed mountain flood monitoring and warning system project as background, discuss the mountain flood monitoring and warning system design and implementation, develop a flexible model for effective early warning flood disasters, to achieve a common platform for cross-GIS The WEBGIS system, enabling the system to adapt to a wide range of needs of municipalities mountain flood prevention, disaster monitoring and warning system for flash floods has an important role in the building.
