Geo—hazard Susceptibility Fuzzy Comprehensive Evaluation in Huangling County
The evaluation result of geo-hazard susceptibility is an important basis for its prevention planning．Relying on survey result of the geo-hazard detailed research project in Huangling County，choose slope gradient，slope height， Stratum strueture．groundwater,integral extent of rock and soil，rigidity extent of rock and soil，maximum rainfall， maximum rainfall intensity,vegetation coverage,impact of human activities as the geo-hazard susceptibility evaluation factors．The susceptibility evaluation zoning of geohazards in Huangling County is performed using fuzzy．comprehensive evaluation method．The evaluation result is divided into three degrees．Study area is divided into highprone．middle-prone and low-prone．Geo-hazard high-prone areas Is mainly distributed in Juhe River valley and Koujia River valley where have loess slope or slope in alternating layers of thin layered semi-hard hard rock and middle lavered hard rock．and widely disturbance to geological environment from the construction of city，town，road，railway and so on．
