摘要
自然作用的环境效应有其两面性，即破坏和改造环境。自然灾害是自然过程中的顶点事件，并造成对人类及其生存环境的冲击和破坏。致灾过程是环境系统中的物质和能量积累和释放过程，并以不同的强度和频率或成灾潜势而分类。灾害的识别和预测以及前兆事件的判定是自然灾害研究的核心。完善的预报系统和有效的抗灾对策是减轻灾害的环境影响的重要措施。灾害风险评估是损失分析的重要环节。全球性事件和极端事件对环境的巨大影响向人类发出警告。从而更突出防灾减损研究的重要性。
The environmental effect of natural process has its duality, destroying and reforming environment Natural hazard is the peak event through natural process, and brings about great effect even damage to humanity with their living envirornment Any hazard process can be recognized as a course of accumulation and release of substance and energy, which can be classified by different intensities, frequencies or hazardous potentialities To identify, predict a hazard and to judge a forewarning event are the key of natural hazard studies A perfect prediction system with affective retarding tactics is important steps of reducing environmental effect from hazards Risk evaluation about natural hazard is an important link in analyzing hazardous losses The great effects on environment from global events and extreme events have sound the alarm to human being The importance of prevention and reduction of hazardous losses, therefore, must be much more highlighted
