| Abstract: | After taking 3S technology-based eco-geological environment investigation in Qianshan scenic zone and its periphery for six months,we select eleven sensitive factors,which include vadose lithology,slope,geological disasters,humidity index,vegetation index,soil layer thickness,soil quality,water table depth,runoff coefficient,mining,tourism and so on,to evaluate the sensitivity of the study region by using BP network model on MAPGIS platform.The result not only truly reflect the present in the studied region... |
| Keywords: | Sensitivity of eco-geological environment 3S technology index system BP neural network model |
