The Juglans County Geological Disasters Susceptibility Partition And Prevention Countermeasures Research

Sensitive indicators of geological hazards was identifying by distribution map of geological hazards and the factors map overlays, quantitative and semi-quantitative, then sensitive indicators overlay. Use the method of scoring or rating given to each factor weight factor, the weight factor associated math, geological hazards have a quantitative basis for division. On this basis, the Yang Bi County prone to geological hazards of the Division, will be divided into four areas:high-prone areas, moderate-prone areas, sub-prone areas and none-pron areas, and based on the results of the Division Yang Bi County geological hazards prevention measures. This paper includes the following aspects:1. Introduce Yang Bi County's regional geological conditions, including terrain landform, formation lithologic and geological structure, climate and hydrological conditions of vegetation conditions in order to determine factors for evaluation.2. Through the field survey's summary, analysis of geological hazards in Yang Bi County, the temporal and spatial distribution of geological hazards.3. Prone to geological hazards evaluation:The Yang Bi County geological conditions of analysis, evaluation factor determining level model, the use of geological disaster risk index for the evaluation of regional sub-units of grid computing, based on geological disaster risk Index of the merger the same unit grid, delineation of geological hazards-prone areas.4. Geological disaster countermeasures:according to the district results of Yang Bi County's geological hazards-prone, Yang Bi County's countermeasures and control of the proposed measures.
