摘　　要：水资源空间均衡是新时期治水理念之一,对实现水资源与经济社会和谐发展具有重要意义。针对抚河流域水资源短缺现状和降雨时空不均的问题,建立了一套面向流域的水资源空间量化与评价模型。模型选取年均降雨量、地形坡度、流域集水面积和流域GDP四个指标作为影响因子,运用GIS空间分析技术将影响因子量化到空间格网,再利用层次分析法(AHP)进行影响因子权重优化设计,实现了抚河流域的水资源空间量化评价。结果表明,模型的整体精度为0.87,其合理性和准确性较好,能为该流域相关研究提供依据,有利于改善当地水状况措施的合理实施。The spatial balance of water resource is one of the concepts of water management in the new period, and it is of great significance to the harmonious development of water resource and economic society. Aiming at the current situation of water resource shortage in Fu River basin and uneven spatio-temporal rainfall, we established a water resource spatial quantification and evaluation model for watersheds. In this model, we selected 4 factors including average annual rainfall, terrain slope, basin catchment area and basin GDP as the influence factors, used GIS spatial analysis methods to quantify the influence factors into the spatial grid, and applied AHP to optimize the weights of influence factors, which realized the spatial quantification and evaluation of water resource in the Fu River basin. The overall accuracy of the model was 0.87. The results show that this model has good rationality and accuracy, and can provide a basis for related research, so as to facilitate the reasonable implementation of measures to improve local water conditions.
