黄明旺许向春  赵学华陈长丘 《广西气象》2007,28(3):50-52,46

通过统计分析海南省澄迈县1959-2004年逐日雷暴资料,找出雷暴发生时空分布特征,统计1995-2004年10a雷暴发生的影响天气系统,计算出各天气系统影响下雷暴发生的概率。分析结果表明：澄迈县雷暴日46a平均雷暴频次437次,年际变化呈波动减少趋势,5-8月是雷暴发生的高发期,占全年雷暴的53%,16-17时是一天中发生雷暴的最高期,西南方向发生的雷暴略多于其他方向,澄迈县受西南低压槽、南海低压槽和副热带高压等天气系统影响时发生雷暴的概率较大。  相似文献

山东省德州市地面沉降控沉分析及建议     

王明珠  万军伟 《中国地质调查》2020,7(3):96-103

山东省德州市地面沉降具有发展历史久、沉降量大、分布范围广、持续发展等特征,地面沉降防治工作形势紧迫。为分析《山东省德州市地面沉降防治规划(2018—2025年)》控沉目标如期实现的可能性,以德州市地面沉降现状及现有防治手段为基础,通过区域地面沉降速率公式量化计算及中心沉降速率预测进行控沉目标可行性分析。结果表明,在最严格的水资源管理制度条件下,控沉目标可以实现。针对地面沉降防治存在的问题,如地面沉降监测手段及监测频率有待提高、防治经费缺乏保障、地面沉降成因机理研究不深入、治理欠缺等,从管理和技术两方面出发,提出了包括健全监测网络、控采地下水、加大地面沉降知识宣传等控沉建议。该研究可为德州市切实有效进行地面沉降防治工作提供参考。  相似文献

山东省主要地质灾害及防治对策     

石宝玉  胡慧萍 《山东国土资源》1998,(2)

山东省主要地质灾害有矿山地质灾害、海（咸）水入侵、岩溶塌陷、水土流失、崩塌、滑坡、泥石流及地面沉降、地裂缝等,其发育和分布严格受地质构造、水文地质条件的制约,同时也受气象、人类活动等因素的影响。这些灾害危害很大,往往造成巨大的经济损失,并伴有人员伤亡。文中对其分布规律、危害程度、致害因素及区域活动性等做了分析,并提出了防治对策及防灾减灾建议。  相似文献

In order to make a comprehensive and systematic evaluation of the status and demands of public service of earthquake disaster mitigation, we launched an investigation with Social Opinion Polling Center of National Bureau of Statistics on the current situation of public service of earthquake disaster mitigation and the demands for it in 2018. The investigation was conducted for 18~75-year-old residents for both urban and rural areas in 31 provinces of China mainland using the Computer Assisted Telephone Interview(CATI)method and 20 078 valid samples were received in total. The questionnaire mainly includes two parts: the current situation assessment and the demand survey. The assessment of public service status consists of five indicators: earthquake emergency drill, knowledge publicity of earthquake prevention and disaster reduction, acquisition of earthquake information, reliability of information released by earthquake agencies, and overall satisfaction. The results indicate that only 27.4% of public have participated the earthquake emergency drill, and 73.5% of public have learned some knowledge about earthquake prevention and disaster reduction in different level. It shows that rural residents have a lower level of scientific knowledge of earthquake disaster mitigation although the rural residents have a higher level of satisfaction. Meanwhile, 82.9% of the public are very concerned about earthquake-related information, and the earthquake information acquisition convenience score is 81.51 points(the full score is 100 points). At present, TV is still the most popular way to obtain the earthquake-related information, besides that, network and the new media app such as Wechat and Weibo play a more and more important role. In terms of the reliability of official information published by the earthquake administration, the score is 83.69 points which indicates that the public tend to believe in official departments. Furthermore, the degree of satisfaction evaluation of public service of earthquake disaster mitigation is marked 76.44 points which shows that there is still much room for improvement. The more educated the public, the less satisfied they are with the public service of earthquake prevention and disaster reduction. The results also show that 51.81% of the public are willing to obtain earthquake warning information at their own expense. As for the demand, the most expectative services for the public are post-earthquake rescue and reconstruction, earthquake warning, and house earthquake resilience test. The results of the investigation may provide some reference for the government to provide better services of earthquake disaster mitigation and to make scientific knowledge popularization in a more scientific way.  相似文献

陡坡陡崖作为一种特殊的地形地貌,是造成滑坡、泥石流等各种地质灾害的重要因素之一。由陡坡陡崖引发的地质灾害会破坏人造地物,对人类的生命财产安全造成严重危害。本文利用DEM数据提取了浙江省温州市的陡坡陡崖,对温州市陡坡陡崖的影响范围进行系统研究,构建了温州市陡坡陡崖的潜在滑坡方向模型,并确定其对人造地物（如道路、房屋）的影响。本文主要研究内容有以下两个：①提取陡坡陡崖并对其潜在滑坡方向进行建模;②根据影响范围提取受影响的人造地物并建立基础数据库。结果表明,温州市的陡坡陡崖数量多,分布范围广且集中,其引发的地质灾害会对人造地物造成严重的潜在影响。本文构建的温州市基础数据库可以描述陡坡陡崖潜在影响的房屋和道路的位置,确定灾害重点防治区域,为温州市的灾害防治工作提供服务。  相似文献
