泰顺县地质环境条件复杂,是温州市地质灾害易发县(市、区)之一,滑坡、崩塌、泥石流等突发性地质灾害较发育,分布具有“点多、面广、规模小、危害大”的特点。2014~2015年,泰顺县开展了1:1万比例尺农村山区地质灾害调查评价工作。通过调查,确定泰顺县现有地质灾害隐患点共169处。其中,滑坡隐患81处,崩塌隐患55处,泥石流隐患33处。威胁2 822人,潜在经济损失7 218.7万元。通过统计分析,确定地质灾害的形成主要与地形地貌、地质条件、气候气象、人类工程活动等因素有关。其中,以人类活动强弱、降雨为主导因素。本文综合分析这些影响因素,可为今后泰顺县开展地质灾害防治工作提供依据和思路,以达到防灾减灾之目的。
Taishun County has complicated geological and environmental conditions and is one of the most prone to geological disasters (cities and districts) in Wenzhou City. The sudden geological disasters such as landslides, collapses and debris flows are more developed and distributed with more points and wider areas and smaller scales , Endanger big "characteristic. From 2014 to 2015, Taishun County conducted a 1: 10000 scale survey and evaluation of geological disasters in rural mountainous areas. Through the survey, Taishun County to determine the existing hidden dangers of geological hazards a total of 169 points. Among them, there are 81 potential landslides, 55 potential landslides and 33 potential landslides. Threatening 2,822 people, with a potential economic loss of 72.87 million yuan. Through statistical analysis, it is determined that the formation of geological disasters is mainly related to topography, geological conditions, climate and weather, and human engineering activities. Among them, the human activity intensity, rainfall as the leading factor. This comprehensive analysis of these influencing factors can provide the basis and train of thought for future prevention and control of geological disasters in Taishun County in order to achieve the purpose of disaster prevention and reduction.
