登陆我国台风的特点及影响分析

Study on impacts of typhoon on China and its characteristics

我国是世界上遭受台风灾害最为严重的国家。为了研究台风在我国登陆后的运动规律及影响状况，选取了1949-2010年登陆我国的台风资料，对台风在我国登陆的次数、登陆地点、活动规律、影响范围、台风暴雨洪水、台风灾害损失、台风水资源等进行了全面统计分析。结果表明，台风登陆我国次数多，影响范围大，常常造成极端灾害天气，引发山洪、泥石流、溃坝等自然灾害；台风也带来了大量的水资源，是许多地区水资源的重要组成部分，应进行合理利用。研究结果有助于有关部门掌握台风在我国的活动规律，认清台风的危害及防台工作存在的问题，以便研究制订相应的对策措施。

China is one of the most severely impacted countries by disastrous typhoons. In order to analyze the laws of typhoon landing and movement and its impacts, the data of landed typhoons from 1949 to 2010 are selected and their characteristics such as landing times, landing location, movement law, impact scope, typhoon storm and flood, typhoon loss, typhoon water resources etc. are analyzed. The analysis results show that typhoon often landed China and impacted a large scope; often caused extreme disaster weather, inducing torrential flood, debris flow, dam failure;also brought large amount of water resources that was an im-portant part of water resources in many areas and should be utilized reasonably. The conclusions are helpful for the related depart-ments to master the damage and existed problems in its defense, so as to propose the countermeasures.
