摘　　要：为研究物元模型在水资源综合评判中的应用 ,首先对物元模型评价方法进行了介绍 ,并在模型构建中引入了层次分析法 (AHP)以确定权重 ,再以河北滹滏平原为例 ,对其农业水资源状况进行了综合评价。结果表明 :滹滏平原的农业用水总体情况的评价值为低水平的 3级 ,与其相应的下一层次区域水资源占有量的评价值为 3级 ,供水评价值也是 3级 ,区域用水水平评价级别为 1级 ,虽然后者为 1级 ,但是区域农业用水总体水供需状况还是非常不容乐观。经验证 ,模型评价符合当地实际情况。本区的研究表明利用物元模型对区域水资源状况进行综合评判具有客观、真实性。In order to identify the feasibility of elements model applied to regional water resource assessment, the element model method was introduced and the AHP method was adopted to calculate the weights of each criterion. As a case, the agricultural water resources of Hufu Plain in Hebei province were evaluated by using the element model. The results showed that the evaluation grade of the total agricultural water resources was low-level of 3 grade in this region; and the evaluation grades of its quantity of water resource, water supply and water utilization were 3, 3, and 1 respectively. the status of the total agricultural water supply and water demand are therefore far from optimistic in study region. The study above results suggest that the application of element models method for evaluating region water resource is feasible and reliable.
