In order to evaluate the spatial differences in water resources sustainable utilization (WRSU), it is vital to adopt a reasonable evaluation method. However, previous studies mostly used a single evaluation method, resulting in differences in evaluation results. In this paper, the Driving–Pressure–State–Impact–Response (DPSIR) model is used for establishing the indicators system for regional WRSU assessment. The improved rank correlation (IRC) model, fuzzy matter element (FME) analysis, grey relational analysis (GRA) model, and attribute recognition (AR) model are used to evaluate WRSU. Then, the fuzzy analytic hierarchy process (FAHP) and set pair analysis (SPA) are applie to establish a combined model to evaluate the WRSU status in nine districts and cities in Fujian Province. The research indicates that (1) it is feasible to apply the combined model framework to evaluate the WRSU, and (2) the spatial distribution pattern of WRSU in Fujian Province shows a decreasing trend from northwest to southeast. Additionally, the water resources endowment, population density and socioeconomic development have become the main factors restricting the WRSU. The assessment results are fundamentally conformed to the actual situation of Fujian. It provides significant for sustainable development of water resources in Fujian.

基于综合评价法的福建省水资源可持续利用评价

为了评价水资源可持续利用（WRSU）的空间差异，采用合理的评价方法至关重要。然而，以往的研究大多采用单一的评价方法，导致评价结果存在差异。在本文中，驾驶-压力-状态-影响-响应（DPSIR）模型被用于建立区域WRSU评估的指标体系。采用改进的秩相关（IRC）模型、模糊物元（FME）分析、灰色关联分析（GRA）模型和属性识别（AR）模型对WRSU进行评价。然后，应用模糊层次分析法（FAHP）和集合对分析（SPA）建立组合模型来评估福建省九个区市的WRSU状况。研究表明：（1）应用组合模型框架评价WRSU是可行的；（2）福建省WRSU的空间分布格局呈现出由西北向东南递减的趋势。此外，水资源禀赋、人口密度和社会经济发展已成为制约WRSU的主要因素。评估结果基本符合福建省实际情况。对福建水资源的可持续发展具有重要意义。评估结果基本符合福建省实际情况。对福建水资源的可持续发展具有重要意义。评估结果基本符合福建省实际情况。对福建水资源的可持续发展具有重要意义。
