提出以四库一体模式实现基于ARCGIS的地质灾害防治决策支持的思路,即以模型为主导,调用方法,提取相关数据计算,对模型进行求解;利用ES对系统判识进行匹配、分析,辅助专家进行决策;将专家决策结果作为知识源提取而存入知识库中.信息系统是整个系统的事务管理层,决策支持系统则是系统应用处理层,两者互为依托.信息系统是决策支持系统的信息源,决策支持系统所产生的结果进入信息系统并对其进行管理,当决策支持系统的模型、方法、知识运作成熟,数据结构化后,又将进入信息系统中,成为信息系统的组成部分.  相似文献

基质-植被系统是岩石边坡植被护坡工程的主要功能构件,其水分循环过程影响工程效应的实现.以高羊茅为建植植物,用TDR水分测定仪对不同表面处理、不同坡度的模拟边坡进行了1年的定位观测试验,研究了岩石边坡基质-植被-大气系统的水分循环过程.结果显示:坡度是影响岩石边坡基质-植被-大气系统水分循环的主要制约因素,坡度增加不仅降低坡面的实际受雨量,同时影响基质的水分输入,系统的蒸散量随坡度增加而降低,但变化幅度较小;试验地气象条件下,生长季的自然降水可满足45°及0°坡面植被所需,75°坡面则出现水分亏缺;由于基质良好的水分物理特性,坡面产流为蓄满产流,受降雨特征及基质初期含水量的影响较小,在同一时空条件下,不同坡面处理的基质含水量表现出微小差异,为喷射混凝土面>灰岩>砂岩.研究从水分循环角度提出了植被护坡技术应用的工程调整措施,为工程应用提供了必要的技术理论支持.  相似文献

Governmental authorities are forced by law to make decisions within the framework of European, national and regional directives in the fields of spatial planning, groundwater and environmental protection. These tasks can be supported by a decision-support system, which integrates data from various sources and helps to make decision processes more effective and transparent. Basic work for such a decision support system has been done in a transnational and interdisciplinary project (Interreg II C: KATER), including metadata definition, metadata system, cartographic tools and GIS tools. The direct integration of these tools and information in the decision process will be implemented in the next few years (project KATER II).  相似文献

边坡治理是边坡工程研究的核心问题,其治理方案的选择直接关系到边坡治理的成功与否。边坡的治理需要很丰富的经验和知识,但知识的获取一直是边坡治理决策的瓶颈问题。长期以来,边坡治理工程实践已积累了大量的工程案例,这些案例中蕴涵了大量的经验和知识,急需挖掘与开发,并应用于边坡治理决策中,进而指导边坡治理工程实践。为此,针对边坡治理决策中的边坡治理方案选择问题,提出了一种基于案例的边坡治理方案选择系统,用以对边坡治理方案选择提供有效的决策支持。该研究具有较好的工程应用价值。  相似文献

A knowledge-based system shell called ‘Confound’ has been developed for the production of decision support systems. It was initially used for developing a system for conceptual foundation design but has subsequently been used for retaining wall, expansive soil and ground investigation applications. It uses a hierarchical object-oriented knowledge base where each object represents a decision in the decision making process. A simple rule-based approach is used to provide advice on the suitability of each potential choice, based on project specific information that is provided by the user. Confound has the ability to work with incomplete information and uses a system of confidence levels so that the user is aware of the confidence with which each piece of advice is given. Conflicting information in areas where knowledge is poorly defined can also be handled. Confound is designed to leave the user in full control. It simply provides comments on suitability (with an indication of confidence) and leaves the final decision to the user.  相似文献

Risk assessment and management, are increasingly established as key procedures in dealing with the range of environmental issues at different scales and of different nature. Although at the EU and international policy level requirements for the use of risk assessment and management are being established through emerging policy and legislation, this demand has not been followed with common guidance on how to do so. This has proven to hinder the effective adoption of such processes, and posed a barrier more so in its implementation for large transboundary issues. In this paper is presented a Decision Support System (DSS) designed to provide a common framework and procedure for environmental risk assessment and management. The DSS is web-based and was developed to enable the formalized and more systematic utilization of risk assessment and management procedures in environmental decision making processes, in particular for users such as public authority officials charged with the responsibility of implementing risk management legal and policy obligations, yet which have limited know how in the field of risk. The DSS presented herein enables environmental administrators and decision makers to undertake generic risk assessment and management identifying areas where detailed risk assessment is required, proposing as well as appropriate risk management options. The web DSS was developed and piloted as part of the STRiM project funded by the European Union. Herein are shown results from the web application which has been trailed successfully in four pilot trials addressing risks of forest damage from storms, water pollution from olive mill waste discharges, wetland loss from water abstraction, and damage from flooding.  相似文献

由于滑坡的复杂性、随机性和不确定性,加之目前的滑坡灾害预测预报理论研究还存在局限性,大大增加了滑坡预报的难度。本文针对目前滑坡预测预报研究中的不足,提出了滑坡综合预测预报信息系统,并对该系统的结构、功能和内容等进行了详尽地设计和开发。滑坡综合预测预报信息系统以G IS为平台,利用智能决策支持系统的理论和方法将以监测资料为依据的滑坡定量预报与以专家经验知识为依据的滑坡定性预报有机结合起来,做到了各取所长,优势互补,实现了滑坡的综合预测预报,提高了滑坡的预报水平。运用该系统不仅可以判断滑坡体的变形破坏机制、目前的稳定性状况和破坏概率,而且可以对滑坡体的变形演化阶段以及滑动时间作出预测预报,从而给滑坡现场工程师的综合判断和决策提供了重要的参考和有关科学依据的实用化工具。  相似文献

A fuzzy sets decision support system is proposed for geotechnical site investigation. The system considers parameters such as geology and soil variability that affect the required number of soundings to adequately characterize a site. It permits also to consider vagueness and lack of information. On the basis of available qualitative and quantitative information, the system allows estimating, for common projects, the number of site soundings. Monte Carlo simulations of entry ranges, where each point has a uniform probability distribution, permit to arrange the output in form of histograms fitted with probability functions. The cases presented show that the fuzzy inference system can be used as a systematic decision support for engineers dealing with site characterization.  相似文献

ICT-based remediation with knowledge information management is presented for the pump-and-treat method of contaminated groundwater. The usefulness of ICT is discussed for monitoring contaminants and groundwater level, transferring data between the remediation well and the remote remediation center, and decision support analysis for controlling the remediation well. A prototype system was developed and applied to field measurement. The prototype system performed reliably for ~600 days. As a decision support analysis, a fuzzy inference model is discussed. The membership functions were determined based on simple reliability theory. The effectiveness of the proposed method was assessed by numerical simulations. The simulation results suggest that the proposed method is likely to reduce the pumped quantity compared to PID control or an engineer’s empirical knowledge. Analysis results are also shown for cancer risks from contaminants and ground settlement risks due to excess pumping up of groundwater.  相似文献

Flood spreading is an inexpensive method for flood mitigation and artificial recharge of aquifers that results in a large budget return for relatively small investment.It is necessary to study some regional characteristics in order to determine the appropriate areas for artificial groundwater recharge by flood spreading in Meimeh Basin, Isfahan Province, Iran. Necessary regional characteristics to be studied are: slope, infiltration rate, sediment thickness, transmissivity, and water quality. In this research to identify suitable areas for artificial recharge several thematic layers were prepared, assigning each layer to one of the mentioned characteristics. The thematic layers were classified to several classes based on the existing criteria. All of the classes of the thematic layers were integrated and analyzed using a decision support system (DSS) in a geographical information system (GIS) environment. Finally suitability of the integrated classes for artificial recharge was identified in which the following classes were separated:(i) Very suitable, (ii) suitable, (iii) moderate suitability, and (iv) unsuitable.The validity of the generated model was verified by applying the model to a number of successful floodwater spreading stations throughout Iran. The verified model showed satisfactory results for all of the stations. The results for Meimeh Basin showed that about 70% of the Quaternary sediments in the studied area are suitable and moderately suitable for artificial recharge by flood spreading.  相似文献
