四川色达县切都柯沟"7·8"泥石流灾害风险评价

2004年7月8日,四川甘孜州色达县歌乐沱乡切都柯沟暴发泥石流.由于前期断断续续一个多月的降雨,使得切都柯沟多处发生崩塌,大量松散固体物质含水量趋于饱和,致使在7月8日一场不大降雨的情况下触发了泥石流.这次泥石流灾害造成的损失虽不十分严重,但泥石流过程比较典型.我们将考察结果整理成文,并用已有的泥石流风险评价模型对其危险度、易损度和风险度作了分类评价,以期为今后的深入研究和防灾减灾实践提供基础.     

From climate change impacts to adaptation: A development perspective for India

India has good reasons to be concerned about climate change as it could adversely affect the achievement of vital national development goals related to socio‐economic development, human welfare, health, energy availability and use, and infrastructure. The paper attempts to develop a framework for integrated impact assessment and adaptation responses, using a recently built railroad coastal infrastructure asset in India as an example. The framework links climate change variables — temperature, rainfall, sea level rise, extreme events, and other secondary variables — and sustainable development variables — technology, institutions, economic, and other policies. The study indicates that sustainable development variables generally reduce the adverse impacts on the system due to climate change alone, except when they are inadequately applied. The paper concludes that development is a vital variable for integrated impact assessment. Well crafted developmental policies could result in a less‐GHG intensive future, enhanced adaptive capacities of communities and systems, and lower impacts due to climate change.     

How Is Household Vulnerability Gendered? Female‐headed Households in the Collectives of Suleimaniyah,Iraqi Kurdistan

This research tries to reach an understanding of the well-being of female-headed household members through a comparison to male-headed household members in the collectives of the Suleimaniyah governorate in Iraqi Kurdistan. Research was undertaken in five collectives in Suleimaniyah during the summer of 1998. The research contributes to the current gender and development debates which are concerned with improving the understanding of the specific gendered forms of disadvantage faced by female-headed households rather than assuming the universal poverty of this group. An understanding of well-being is approached through a broad conceptualisation of vulnerability in preference to a narrow poverty definition. That the findings of this research are complex attests to the multi-dimensional and mutually constitutive gendered experiences of vulnerability. The definitive conclusion to emerge from this research is a refuting of the rhetoric-fuelled stereotype that households headed by women are at a disadvantage in all the dimensions of vulnerability in comparison to households headed by men. The research also establishes the methodological necessity of examining intra-household distributive mechanisms that determine individuals' well-being.     

Degradation Model: A Quantitative EIA Instrument,Acting as a Decision Support System (DSS) for Environmental Management

Environmental assessment of alternative development plans, programs, and policies may bring conflict among decision-makers, particularly when some quantitative measures for decision-making are needed and where cumulative impacts are neglected. Environmental impact assessment (EIA) and environmental economics theories, despite their usefulness, are not capable of addressing those issues and problems alone. In recent years, the decision support system (DSS) has provided some solutions, but mathematical analysis of the system to show the internal structure of the problem is not always possible. To addres the above shortcomings and ongoing problems of decision-making in Iran, a degradation model (DM) was introduced as an instrument of EIA, to act as a DSS for managers. The model is a compromise between knowledge-based decision support systems, detailed models, digested information models, and the basic theorem of environmental economics. In the present study (1996–2000), the model was applied in three provinces of Iran, representing three of four biogeographical regions of Iran. The study area was divided into a set of grids (100 km²). The degradation coefficient (H) was computed for all grids (1333), representing the degree of degradation in the grid. It is obvious that the higher the coefficient the more area is degraded and less prone to further development, and vice versa. In order to provide decision-makers with a set of quantitative measures to observe impacted areas (critical and noncritical) for resource allocation and further development, the degradation coefficients of all grids were classified into categories and criteria, using a fuzzy set theoretic approach. Accordingly, only 24% of study areas are prone to further development. The degradation model as a knowledge-based decision support system has its strengths and weaknesses, but it has solved managers' ongoing problems in Iran and it could be used elsewhere.     

中国雪灾时空变化及畜牧业脆弱性分析

以省级报刊为主要信息源,辅以气象部门统计资料,获取了县域统计单元的雪灾信息,重建了中国1949～2000年雪灾的时空分布格局。对雪灾的时空变化分析结果表明,中国雪灾存在3个高发中心,即内蒙古中部、新疆天山以北和青藏高原东北部;雪灾年际波动幅度大,总体呈现增长趋势。本文还进一步分析了中国雪灾均灾次的高、低值区与草场退化程度的关系,从承灾体脆弱性的角度揭示了雪灾格局形成的机制。

The Vandaclim Simulation Model: A Training Tool for Climate Change Vulnerability and Adaptation Assessment

This paper describes a training course on climate change vulnerability and adaptation assessment. The course, developed in partnership with the CC:TRAIN Programme of the United Nations Institute for Training and Research (UNITAR), aims to enhance the capacity of developing countries to make their national communications to the United Nations Framework Convention on Climate Change. The paper focuses on a simulation model called VANDACLIM, which was developed as a pedagogical tool to facilitate the training. Four sectors are modelled within VANDACLIM (agriculture, public health, water resources, and coastal zone) and are used as a basis for helping to conduct an integrated, multi-sectoral assessment for the imaginary, sub-tropical country of Vanda. The learning-by-doing approach, encapsulated in the application of VANDACLIM to complete a mini-assessment for Vanda, proved to be very successful when trialled at a training workshop in Zimbabwe. Both the training course and VANDACLIM have been adapted subsequently for application in small island states and plans are underway for extension to other environments and regions of the world.     

基于链式中介效应的辱虐管理与安全绩效关系研究

为明晰辱虐管理、自我损耗和工作倦怠对安全绩效的作用机理,在文献研究和开放式访谈的基础上,建立四者关系的假设模型。采用辱虐管理量表、自我损耗量表、工作倦怠量表和安全绩效量表对389名员工进行调查,通过SPSS和AMOS进行相关分析和中介效应检验验证假设模型。结果表明,辱虐管理、自我损耗和工作倦怠两两之间均呈显著正相关,而辱虐管理、自我损耗和工作倦怠三者均与安全绩效呈显著负相关。辱虐管理不仅可以直接预测安全绩效,还可以通过3条路径间接影响安全绩效:通过自我损耗的独立中介作用;通过工作倦怠的独立中介作用;通过自我损耗和工作倦怠的链式中介作用。有效干预辱虐管理、自我损耗和工作倦怠,能提升安全绩效水平,减少人因失误。
