- Abstract:
- The investigation on small basin disaster-pregnant geological environment is an important basis to analyze the spatial and temporal distribution of geological disasters and disaster mode. It is also important to complete geological disaster-prone degree and zoning assessment of geological disasters and to propose comprehensive countermeasures. The geological hazard survey in Liupanshan Town of Jinghe River Basin analyzed the relationship between topography, geological structure, engineering geological rock group and geological disasters. The results show that: (1) the large landscape units and patterns obviously control the distribution of geological disasters, the geological disasters within the different types of landforms, the degree of development and distribution have some differences, the statistics shows that landslide mainly developes in the erosion construction hilly and low mountain areas, debris flow mainly developes in the low mountains, and collapse mainly developes in the valley slope zone and fault, the distribution of geological disasters developes densely along the border of general topography, linear distribution is common along the fault; (2) the weak mudstone rock group are the region’s major slide-prone stratum, controlling the distribution of geological disasters, the amount of the landslide has little correlation with landslide density in the range of different engineering geological rock group; (3) the regional geological structure not only controls the stratum spread, also controls the development of regional geological disasters. Different fracture highlights some differences.
