平原地区洪灾风险评价的GIS方法研究 --以荆州6县市为例

平原地区因地势低平。水网发达而常遭到洪水的威胁。这种威胁既有来自过境洪水的洪灾．也有来自本地因暴雨引起的涝灾。如何考虑它们两者的相互影响以及洪水灾害的自然与社会经济属性，进行洪水风险评价是一个比较困难的问题。在地理信息系统软件ArcGIS8．1支持下，既考虑过境洪水与本地涝灾，也考虑承灾体的易损性(包括人口、交通线与经济)，还考虑抗灾能力，以GRID模块的地图代数作为运算手段，用AHP法确定因子的权重，建立了评估平原地区的洪灾风险的计算模型和评价方法，该模型运用于长江中游洪灾风险比较严重的地区——荆州地区的6县市．取得了比较好的效果。     

炮采放顶煤采空区自然发火的数值模拟应用

针对炮采放顶煤开采采空区容易发生自燃问题，基于漏风渗流方程、气体渗流一扩散-氧消耗方程，建立了采空区自然发火非稳定数值模型，采空区按非均质考虑，耗氧汇按煤矸氧化和瓦斯涌出稀释两方面综合考虑，用有限元数值方法联立求解模型。结合羊草沟矿实例，通过该矿自然发火后来的测试区的现场实测结果，拟合反演得到采空区煤的耗氧速度、瓦斯涌出强度和渗透特征参数，用确定的模型分析了前段出现自然发火的原因；描绘了炮采放顶煤开采时采空区冷却带、自燃带和窒息带等三带的形状，指出冒落压实的不均衡的非均质采空区，自燃点在偏人风一侧。用三带划分理论讨论了工作面参数（风量、推进度、控顶距）同自燃的量化关系，提出了从根本上预防采空区自然发火的途径与方法。

A critical review of the water quality classification system in Turkey: A case study on Meric Basin

An 11-year period of water quality data, collected by the Directorate of Sate Water Works of Turkey are thoroughly analyzed for the purpose of implementing water quality classes to water resources in the Meric Basin, located on the European land mass of Turkey. Water quality parameters are divided into four groups as physical, organic, inorganic, and bacteriological. The quality class of each group is evaluated by taking into account the poorest quality of any parameter in the group, after which a quality rank is assigned to the sampling station and the waterbody in question. This method of water quality classification imposed by the Turkish Water Quality Act, is then criticized with respect to a statistical approach.     

涪江上游滑坡相关因素研究

采用灰色系统理论的关联度分析方法，研究了涪江上游骨滑坡的主要形成条件及触发因素。结果显示，相对主同差是滑坡的主要形成条件，地震是滑坡的主要触发因素，此外，还对滑坡相关因素进行了相关显著性比较，评价了每项相关因素的其中所起的作用，最后讨论了灰色系统理论的关联度分析方法在滑坡研究中的利弊。     

长江上游攀西—六盘水地区资源开发与环境保护

长江上游攀西——六盘水地区是个资源富集的“金三角”。通过交通先行,加快资源开发,对增强21世纪经济发展后劲意义重大。但生态环境恶化,急需加强保护。

江淮流域大洪水的因子分析及成因链初步构造

结合 1998年长江流域的特大洪水 ,提出了洪水成因链的概念 ,分析了各个物理因子对江淮洪水的影响。指出影响江淮洪水的物理因子都是层层相接、环环相扣的 ,它们组成了一个互相联系、互为因果的洪水成因链。成因链上物理因子之间的正反馈作用和消长作用 ,导致成因链上各个因子的致洪理论都不能完全地自圆其说 ,因而也无法完全确定地用于洪水预测。只有深入探讨洪水成因链上物理因子之间的正反馈作用和消长作用 ,对它们进行全面综合的诊断分析 ,才能提高江淮洪水预测的准确率。     

Sustainable Development and the Role of the Financial World

The incapacity to finance sustainable development through philanthropic official assistance turned the Johannesburg Summit to business world and the financial industry. Pioneering financial institutions – including development banks and private banks – have developed a wide range of innovations that can support sustainable development. This article highlights a few innovative products and markets and focuses on the progress made by financial players on the level of standards, metrics and guidelines to improve sustainability management systems, reporting and accounting practices and the multi-stakeholder dynamic. The role of the socially responsible investing (SRI) community has been underexposed by the Summit. Through its voice and market success, SRI has moved from a green market niche to the mainstream, however not becoming mainstream. The invaluable levering effect of SRI has just been discovered by authorities and market regulators and is becoming instrumental. In order to show the business case of Corporate Social Responsibility and to prove the financial viability of the People, Planet, Prosperity investing approach, the SRI community should critically reflect on its own quality assurance systems, sound disclosure and verification practices.
