This paper presents a geo-statistical method to study the spatial relationship between landslides and their inner-factors on the regional scale in order to predict the regional susceptibility of landslides. The approach is based on digital databases, along with such methods as statistics, spatial analysis based on Geographic Information System, and interactive mapping. The prediction map of study...
There is a good correlation fractal value of high complexity and fault systems. Generally have higher value, fault systems of fractal dimension in fracture length, smaller, branch, tectonic deformation and fracture large extent. Otherwise, the fault systems have lower fractal dimension. Through the different methods of fractal dimension is different, have different meaning in the same place. In this...
In this study, total of 261 soil profiles were reported to investigate the Cu spatial distribution and vertical variation in Guangdong province using geography information system (GIS) and geostatistics. Findings indicated that the Cu geometric mean concentration of 11.2 mg/kg in surface soils is lower than those in China, which ranged from 0.12-98 mg/kg. The influence of soil properties on Cu concentration...
Rainfall, especially rainstorm is one of most important triggering factors to the activities of geological disasters, Which has brought great losses to people's life an property. In the support of GIS technology, taking Hubei Province,China as study area, based on detailed analysis of the geological disasters influence factors, this article imported matter-element comprehensive evaluation model to...
Fault system is a significant evidence of tectonic movement during crust tectonic evolution and may play an more important role in oil-gas accumulation process than other tectonic types in sedimentary basin. Carboniferous surface faults in Junggar Basin developed well and varied in size and distribution. There are about 200 faults in Carboniferous, and 187 of them are thrust faults. Chaos-fractals...
In the Three Gorges reservoir, considering damage to residents and man-made structures by natural hazards, landslide is the most important disaster in the new county seat of BaDong. For this status, landslide hazard zonation is an effective solution for land management. Firstly, based on the analysis of the landslide geological background, by reducing the material composition and historical geological...
A city three-dimensional foundation information consultant system is developed based on random field theory to predict unknown geotechnical parameters. Taking the geographical information system (GIS) as development platform, the general structure module and database of the system is designed. By means of writing programs in Mapinfo, Visual Basic and Excel, dynamic multi-way inquiry, statistics can...
Based on the macro-scale digital elevation model data, by using ARC/INFO software, the relief degree of land surface (RDLS) of 10 kmtimes10 km grid size is extracted and mapped in urban agglomerations of China. Then this paper systemically depicts the distribution rules of RDLS in urban agglomeration and its correlation with population distribution by analyzing the ratio structure and spatial distribution...
