随着我国经济的飞速发展,高速公路建设越来越多,地震监测设施和观测环境因其建设被危害的现象越来越严重。地震监测设施和观测环境保护行政执法的目的是保证地震监测设施完好、排除地震监测设施正常效能范围内的干扰源,保障地震监测预报工作质量。这类行政执法实际上是跨学科的,不仅要熟悉防震减灾法律法规,还需要了解测震、电磁、地壳形变和地下流体观测的地震专业知识。本文列举甘肃省办理过的3起典型案件,剖析该类案件行政执法各阶段的工作重点,提出高速公路建设危害地震监测设施和观测环境行政执法中存在法律依据缺位、执法主动性不够、执法效率低下、相关宣传不够的现实问题,通过分析、论证,给出有效建议。 相似文献

美国的地震监测工作起步较早,在台网设计、设备研制、软件研发、标准制定、数据管理和新技术应用等领域处于领先地位。近年来,随着移动互联网的发展,以及强震动观测、地震预警和大规模流动台阵等项目的推进,美国的地震数据产品实现了从单一向多元化、定制化的跨越。我国的地震监测工作虽起步较晚,但随着国家地震烈度速报与预警、“一带一路”地震监测台网和中国地震科学实验场等一系列重大项目的实施,地震站网密度、监测预警能力、地震数据智能处理、服务水平和新技术应用等方面都取得了跨越式发展。为更好地了解国际地震监测现状,文章从地震监测架构、地震台网布局、数据处理系统、地震预警系统和数据产品五个方面介绍了美国的地震监测工作进展,并与我国地震监测进行对比分析,可为我国地震监测预警事业规划和发展提供参考。 相似文献

A procedure for short-term rainfall forecasting in real-time is developed and a study of the role of sampling on forecast ability is conducted. Ground level rainfall fields are forecasted using a stochastic space-time rainfall model in state-space form. Updating of the rainfall field in real-time is accomplished using a distributed parameter Kalman filter to optimally combine measurement information and forecast model estimates. The influence of sampling density on forecast accuracy is evaluated using a series of a simulated rainfall events generated with the same stochastic rainfall model. Sampling was conducted at five different network spatial densities. The results quantify the influence of sampling network density on real-time rainfall field forecasting. Statistical analyses of the rainfall field residuals illustrate improvement in one hour lead time forecasts at higher measurement densities. 相似文献

Destructive earthquakes have caused great damage in China and the United States and collapsing buildings havecaused many deaths and injuries. The field of earthquake engineering studies earthquake hazards, the occurrence ofearthquakes of various magnitudes, the nature of the ground shaking during an earthquake, the vibration of structuresduring earthquakes, the strengthening of existing structures and the design of new structures to be earthquake resistant,and finally, how to cope with earthquake damage and restore a city to normal functioning. Such efforts are in progressin both countries, but unfortunately, the language barrier interferes with the free flow of information between China andthe Untied States. It would be mutually beneficial if some means could be developed to promote the exchangeof information across the Pacific Ocean. This new journal has been established for this purpose and its success willbe an important step in promoting earthquake engineering in China and the United States. 相似文献

正Global Change includes climate change and other environmental changes caused by the joint interaction among various layers of Earth. From the positive side, global change provides new opportunities to human and other living forms on Earth. In the meantime, it creates tremendous challenges and negative impact. At present, the negative impacts have reached all primary processes of the global ecosystem and every aspect of human society, especially causing degradation of the ecosystem. For instance, intensive deforestation causes decline of biodiversity; global warming causes sea level rise and increases 相似文献
