Landslide hazard is one of the most serious and frequent natural hazards. Each year it causes a loss up to billions of dollars in the whole world. This hazard gives great damages to the country and people's lives and properties. And they are the very single--landslides that lead to the loss directly. So, in front of the serous landslide hazard, in order to measure the influence of hazard on life and property a risk assessment theory needs to be applied to. At the same time, Lijiaxia landslide which is in Long area, Shan Xi province, is unstable and imperiling life and property at present, so it is very necessary to make a risk assessment.

滑坡灾害是地质灾害中最为常见且危害严重的灾种之一，每年因滑坡灾害造成的损失数以亿计，给国家和人民生命财产带来巨大损失，产生严重社会影响，而最直接造成损失的，正是一个个的单体滑坡，因此，面对严重的滑坡灾害，为合理确定并评价滑坡灾害对生命财产的影响尺度，需研究和应用单体滑坡风险评价理论和方法；同时，作为单体滑坡的陕西省陇县李家下滑坡目前处于不稳定状态，且威胁到当地居民的生命财产安全，对其进行风险评价尤为重要。

Probability: Studies on the emerged accident probability of major hazard carrying the Markow process; Severity: By applying the grey system theory , on the base of the same kinds of accident-economy cost, establishes self-adapting GM (1,1) forecasting model and the model with the residual error being amended in a bid to calculate accident-economy cost; Safety management: Establishes the dynamic comprehensive analytical method on major hazard and safety management of the major hazard by applying the grey system theory and fuzzy math theory.

其次，针对重大危险源原有的二维评价方法所存在的局限性，建立了以可能性、严重性、安全管理水平为三维矢量的评价方法，并对这三个矢量进行了定量计算：可能性：运用马尔可夫过程计算了重大危险源发生事故的概率；严重性：运用灰色系统理论，根据已有的同类事故经济损失的统计资料，建立自适应性GM(1，1)模型及残差修正的模型，预测重大危险源发生事故的经济损失；安全管理水平：运用模糊数学理论和灰色系统理论，建立了重大危险源安全管理水平动态综合分析法。

Based on practical demands of regional accident emergency management of major hazard installations, non-structural fuzzy decision method and accident consequence simulation methods are co-method to present safety management administration and related enterprises a multi-criteria decision support method, which is focused on enterprises that might be affected by the potential accident consequence of major hazard installations, for regional accident emergency management of major hazard installations, this method is aimed to optimize the management of emergency resource, promote the performance of safety management system, decrease the fatalities and property loss.

针对目前我国应对重大危险源突发事故的管理和决策主要依赖于相关领导或专家掌握的知识及经验的现状，将非结构化模糊决策方法(Non-structural Fuzzy Decision Method， NSFDM)和事故后果模拟方法相结合，以区域范围内受重大危险源潜在事故影响的企业为决策对象，以减小事故影响范围，降低事故严重程度为目标，建立起重大危险源区域事故应急决策的多准则决策方法，以期帮助安监职能部门优化配置应急救援资源，提高应急响应绩效，减少国家和人民的经济和财产损失。

Uncertainties exist in either aleatory variability or epistemic uncertainty, but a weighted average of various alternatives in probabilistic seismic hazard analysis and the combination in methodology of PSHA and DSHA (deterministic seismic hazard analysis) should better prevent it from producing an extremely biased output of hazard estimates.

由于输入模型中不确定因素的存在，如输入参数的随机性和科学分析方法本身的不确定性，对分析结果的不确定性需审慎对待。通常对不同的模型或参量，包括地面衰减模型，进行加权平均可较为合理地减小结果的偏差。概率分析和确定性分析方法的结合亦为可取之有效途径。

Most studies on fire prevention focus on buildings themselves, such as fire protection facilities, the usage of uninflammable materials, the design of partitions for preventing from fire hazard, etc. However, few researches discuss how to manage fire hazard in community scale concerning surrounding environments, space structure, land use, etc. Recently, urban plans are requested to take hazard mitigation into account. It demands more studies on the urban scale. Hence, this research proposes an evaluation method to assess fire risk degree in terms of urban blocks.

然而，目前一般消防单位对於消防安全之检视大多仅著眼於建筑物内部的消防设备或是建物内部防火设计是否妥当等硬体面，但从都市整体角度，即周边环境、空间结构以及建物、土地使用等因素对於火灾之影响则甚少探讨之，再加上都市防灾计画与检讨中亦须风险的资讯，因此本研究拟就都市街廓尺度，评估其火灾风险度，以作为都市地区消防规划、通盘检讨以及都市更新等政策决定之参考依据。
