玛纳斯河流域生态问题的潜在风险性评估
玛纳斯河流域 生态经济功能区划 生态问题 生态风险评估
2013/9/24
玛纳斯河流域是中国干旱区最具代表性的山地-绿洲-荒漠生态系统,三大生态系统表现出的区域生态、经济要素的空间状况有所分异,所存在的生态安全问题的表现形式也各不相同。根据流域土地利用和水资源数据库,在生态经济功能分区的基础上,针对流域不同分区存在的生态安全问题,选取相应的17个生态风险评估指标,建立了生态-经济风险性评价模型,对流域各个生态经济功能亚区的生态问题潜在的风险性进行了生态风险评估。结果表明...
This summary gives an overview of EU-OSHA’s key activities in 2011 and offers an outlook for 2012. Highlights of the year include the flagship Foresight project on green jobs; secondary analysis of th...
Experience shows that proper risk assessment is the key to healthy workplaces. Yet carrying out risk assessments can be quite challenging, particularly for micro and small enterprises which may lack t...
针对海洋立管破坏失效事故资料不完备及发生概率缺乏精确值的现状,提出了基于模糊故障树的海洋立管破坏失效风险分析方法。通过对现有的海洋立管破坏失效事故原因的统计分析,建立了以"海洋立管破坏失效"为顶事件的故障树。在对故障树进行定性分析的基础上,得到了引起海洋立管破坏失效的105个各阶最小割集,确定了海洋立管发生破坏失效的主要模式。采用专家判断法与模糊集理论结合的方法对故障树进行了定量分析,评估了故障树...
改进的物元可拓模型在台风灾害预评估中的应用
台风 灾害预评估 可拓法
2013/9/24
以数值天气预报产品为信息源,选择降水量、降水强度、最大风速、经济易损性作为评价因子,建立了可拓模型,并进行了台风灾前的灾害预测性评估。针对物元可拓法在台风灾害预评估应用中的不足之处(当待评估的数据超出某一指标评价指标范围,其关联度函数就会出现无法计算的情况),对原有模型中经典域的量值作规格化处理和改变关联度计算,以海南岛的台风历史灾害数据为基础,建立了新的评估模型,并将GIS与评估模型结合开展实例...
台风危险性分析是台风损失估计及防灾减灾的基础。对基于数值模拟的台风危险性分析所采用的随机台风概率模型、随机抽样模拟方法和极值风速预测进行了回顾与评述,包括台风关键参数概率模型及其相关性、台风路径模型、台风登陆衰减和海陆风速转换模型以及台风极值风速概率模型,并针对我国东南沿海地区台风危险性分析数值模拟采用的相关模型给出了相关建议。
