As the main means of monitoring and early warning of geological disaster, the slope stability analysis is an important part of the geological disaster prevention project. GIS plays an important role in the evaluation of slope stability due to its powerful functions for data processing and spatial analysis. This article discusses the key technology of GIS applied in the slope bolt support design...
Snow drifting is a typical natural disaster, and an increasing importance has been attached to its theory research and field observation for the sake of cold region engineering. Numerical simulation, as an efficient method of studying snow drifting, promises to be widely applied in this field. In this paper, the finite element method is used to simulate the wind velocity field. Selected upwind,...
Deforestation or vegetation degradation is one of the main drivers of global earth changes, which has significant consequences in terms of ecosystem performance and biodiversity conservation. One of the ways for studying vegetation changes as the most important indicator of land degradation is remote sensing. In this study, in order to monitor the vegetation degradation trend in Ilam Province.A...
