Study on spatial distribution regularity for sudden occurrence of water and soil hazards in mountain area
浙江突发性山地灾害与区域地质构造的相关性研究

Based on the general survey data of mountain hazards. By using MapInfo and ARC/Info software, the relationships between the mountain hazards and the three kinds of geological structure were studied. The results showed that the mountain hazards have zonal distribution along the discordogenic fault, porphyritic distribution under the effect of volcano-tectonic, and vertical distribution under the effect of neotectonic movement. The distribution regularity of mountain hazards can provide scientific foundation for environmental evaluation and regionalization, and prevention countermeasures in mountain area.
