Mine contamination is one of the main obstacles to economic recovery and other types of progress in mine‐affected countries. Therefore, the primary goal of humanitarian demining operations is to clear all suspected minefields and restore them so as to make them available for their previous use. The customary financial shortfall results in the need for priority setting in the mine removal process. This paper describes and investigates a new approach to priority setting within mine action, with the introduction of a hierarchic GIS‐based decision support system (DSS). The proposed DSS is aimed at determining the objective priorities required to reduce the risks stemming from mine contamination. DSS is based on a combination of GIS analysis and a multicriteria method in order to enable efficacious mine action management, namely setting humanitarian demining priorities in order to optimally reduce the risk caused by mines. GIS is outlined as a powerful tool for the generation of aggregated information used in multicriteria analysis, as is the link between hierarchic decision levels in the proposed DSS. The results of a demonstration of the proposed GIS‐based DSS on mine‐affected water resources in Croatia are supplied. 相似文献

Abstract A primary goal of the NERC/ESRC Land Use Programme (NELUP) was to design and build a decision support system (DSS) to model rural land use and its change due to environmental and agricultural policy. The effects of policies are measured in terms of economic, ecological and hydrological parameters, with land use and land cover being the uniting factors. The DSS incorporates access to a large database and a suite of complex models. The DSS is user-friendly, produces meaningful graphics, and is almost entirely mouse-driven. This paper describes the NELUP view of policy making and DSS, the NELUP database and the DSS models and interface philosophy and design. The results of workshops, conducted with potential users of the DSS, are discussed and summarised. 相似文献

基于GIS和BP神经网络的区域农村贫困空间模拟分析——一种区域贫困程度测度新方法 总被引：5，自引：0，他引：5
基于区域农村贫困程度测定方式不完善及缺乏地理视角的现状,选取四川省36个国家级扶贫县为实证对象,构建自然社会经济全面耦合的农村贫困测度指标体系,分析区域农村贫困的影响机制,并运用GIS与BP神经网络模拟区域自然致贫指数、社会致贫指数和经济消贫指数的空间分布格局。在此基础上,提出了全面表征区域农村贫困程度的区域扶贫压力指数——一种新的区域农村贫困测度方法,为国家扶贫政策文件《财政扶贫资金管理办法》中关于财政扶贫资金基于区域农村贫困程度分配提供实践基础。 相似文献

We use coupled numerical models (HydroTrend and SedFlux) to investigate the dispersal and accumulation of sediment on Poverty Shelf, North Island, New Zealand, during the past 3 kyr. In this timeframe, we estimate that the Waipaoa River system delivered ∼10 Gt of sediment to Poverty Shelf, 5–10% of which was transported to the outer shelf and continental slope. The domain of the two-dimensional model (SedFlux) is representative of a 30 km traverse across the shelf. Comparing the model output with seismic reflection data and a core obtained from the middle shelf shows that, without extensively modifying the governing equations or imposing unrealistic conditions on the model domain, it is possible to replicate the geometry, grain size and accumulation rate of the late Holocene mud deposit. The replicate depositional record responds to naturally and anthropogenically induced vegetation disturbance, as well as to storms forced by long-period climatic events simulated entirely within the model domain. The model output also suggests that long-term fluctuations in the amount and caliber of river sediment discharge, promoted by wholesale changes in the catchment environment, may be translated directly to the shelf depositional record, whereas short-term fluctuations conditioned by event magnitude and frequency are not. Thus on Poverty Shelf, as well as in depocenters on other active continental margins which retain a much smaller proportion of the terrigeneous sediment delivered to them, flood-generated event beds are not commonplace features in the high-resolution sedimentary record. This is because the shelf sedimentary record is influenced more by the energy available to the coastal ocean which helps keep the sediment in suspension and facilitates its dispersal, than by basin hydrometeorology which determines the turbidity and velocity of the river plume. 相似文献

区域多维贫困测量的理论与方法 总被引：8，自引：4，他引：8
贫困包括区域贫困和个体贫困,两者均具有多维属性。区域多维贫困是贫困地理学研究的重要内容,深度贫困地区是区域多维贫困的集中表现,是当前和未来脱贫攻坚的贫中之贫、困中之困、坚中之坚。本文以空间贫困理论为基础,界定了贫困地域系统和区域多维贫困的概念,并探究了区域多维贫困测度指标体系与评估方法。据此,以中国334个深度贫困县为研究对象,运用BP神经网络模型和ESDA技术刻画了中国深度贫困地区的多维贫困空间格局。结果表明：① 区域多维贫困是贫困地域系统发展演化过程中“人”“地”“业”三个核心要素耦合失调的一种外在表现形式,是特定地域在生态环境劣势、经济劣势、社会福利劣势上的综合表现,包括生态贫困、经济贫困和福利贫困3个维度。② 深度贫困地区最“深”的地方在青藏高原,最“深”的短板在公共服务和基础设施。从单一维度的贫困指数来看,深度贫困地区的福利贫困指数（WPI）>经济贫困指数（EPI）>生态贫困指数（NPI）,三者平均值分别为2.77、2.66、1.89,贫困人口社会福利供给不足和公共服务短缺是深度贫困地区最突出的问题;从多维贫困指数来看,青藏高原是区域多维贫困指数（RMP）的高集聚区或热点区,生态贫困、经济贫困和福利贫困程度均显著高于其他地区。③ 区域多维贫困指数能较好地揭示特定区域的贫困状况。在地理位置偏远、生态环境极其脆弱、区域劣势突出的地区,区域贫困和个体贫困在空间上高度重叠。 相似文献
