为解决强震破坏范围广带来的跨区域应急救援问题,以京津冀地区为例,基于强震情景构建的方法,开展强震后跨区域协同应急需求、内容、任务、机制、保障措施等研究。假定京津冀交界地区发生7.8级强震,其地震参数与1976年唐山7.8级地震一致,基于人员伤亡、建筑物破坏、道路堵塞等情景分析模型,分析北京、天津、河北等地破坏情况,提出震后京津冀地区跨区域协同应急应对需求与任务,构建了应急协同体系分层模型,从应急指挥、应急通信、救援队伍、转移安置、工程抢险、交通管制、医疗防疫和社会治安协同等方面提出了应急协同机制内容与方法。引入了“目标-行动-反馈-调整”质量管理循环模型,构建了京津冀地区跨区域地震应急协同流程,对强震巨灾现场救援行动进行有效管理,提升跨区域地震救援工作的规范性,并针对性地提出了京津冀地区跨区域协同应急机制建设的保障措施。 相似文献

地震等突发性公共事件发生时,应急预案是应急准备的核心内容。预案的展现形式是否直观有效,是预案能否及时准确的为指挥人员提供指导性意见的关键。本文以地震应急预案的结构化研究为基础,从文本结构化和系统集成结构化角度进行分析,建立地震应急预案信息系统,探讨地震应急响应过程中联动服务的实现。 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

Water quality analyses for the Niger River for the 1980/81 hydrological year are presented. The samples were collected from the main river at Lokoja, and from two main tributaries, the Kaduna and the Benue Rivers. Different water types were distinguished by the concentrations of major ions. The type Ca > Na > Mg > K - HCO3 > SO4 > Cl was represented at all stations during at least part of the year. Chloride was found to dominate the sulphate ion in the Kaduna and Niger, while the Benue maintained a higher concentration of sulphate relative to chloride all year round. Distinct patterns of seasonal variation in the ion concentrations were observed, particularly for the samples collected at Lokoja. Low ion concentrations were prominent during periods of high discharge, while low flow periods coincided with high dissolved ion concentrations. The contribution of rainwater to the total dissolved solids in the river waters was assessed indirectly using rainwater chemistry data from the Gulf of Guinea. The estimated rainwater contribution to the Lower Niger amounts to 5.15 mg 1?1. Geochemical weathering calculations involving reactions of the four major minerals of granitic rocks - anorthite, biotite, albite, and K-feldspar - with carbon dioxide and water, can account for the average water composition of the Lower Niger. The proportion of the ionic components was also related to the occurrence of the respective element in the minerals. 相似文献
