【摘要】 在自然环境和人为因素影响下,广东的地质灾害种类主要有地震、滑坡、崩塌、水土流失、岩溶塌陷、坑道突水、软土变形、地面沉降、地裂缝、水库诱发地震、河港淤积、地方性氟中毒等。根据地理分带性、区域地壳运动、岩土特征、地质灾害组合类型及发育程度,将全省地质环境划分为三个区、七个亚区,对灾害发展趋势进行预测,并提出了防灾减灾对策。更多还原

【Abstract】 The main types of geological hazard in Guangdong province, either induced from natural factors or influenced by human activity, are earthquakes, landslide, collapse, soil erosion, Karst collapse, water bursting in excavations, deformation of soft soil, ground subsidence, ground crack, reservoir-induced earthquakes, siltation of river and harbour, and endemic fluorosis. According to the geographic zoning, regional crustal movements, natures of rock and soil, and the geological hazard combination type and its intensity, Guangdong province is divided into three regions and seven subregions of geological enviroment. then the trend of hazards is predicted and some measures for preventing and reducing hazards are proposed also.更多还原
