| 摘 要： | 火山活动是地球内能和热量释放的一种形式，火山喷发对人类生存环境的影响包括两个方面，即：灾害效应和资源效应。一方面，火山喷发是一种自然灾害，它不仅对人类产生直接危害，而且还会诱发次生灾害或对人类的生存环境造成长期的危害。其中对人类生命财产构成严重威胁的火山灾害有熔岩流、火山碎屑流、火山泥流和火山海啸。另一方面，火山活动为人类提供了丰富的矿产资源、地热资源和旅游资源。

| Abstract: | The volcanic activity is a way with which the internal energy and heat of the Earth release. The effect of volcanic eruption on the environment on which huma n being exist are disaster effect and resources effect. The volcanic eruption is one of the natural hazards. Volcanic eruption not only endangers human being bu t also induce some secondary or long term hazards. Lava flows, pyroclastic fl ows , lahars and volcanic tsunamis are the major hazards that threaten the life and property of the people. The volcanic activity also provides a wealth of minerals ,geothermal energy and beautiful landscape. |
