Abstract In order to timely understand the status of sustainable utilization of urban water resources and to effectively plan and manage the use of water resources, in this study, an extension evaluation method is used to evaluate the sustainable utilization of water resources. Firstly, a sustainable utilization index system of water resources is constructed from the perspectives of water resources conditions, development and utilization, social economy, ecological environment, and water resources management. Then, according to the incompatibility and relevance of some indexes, the extension evaluation model is established based on the theory of extension evaluation. Finally, the extension evaluation model constructed in this study is used to evaluate the sustainable utilization of water resources in X city. The results show that the level of sustainable utilization of water resources in X city is level M, which is consistent with the current reality of the sustainable utilization of water resources in X city and verifies that the extension model proposed in this study is feasible. Extension matter-element model has more advantages in fine analysis and trend analysis. This study provides a good theoretical basis for the management and utilization of water resources in China.

Introduction Human survival and production cannot be separated from water resources. Water is the basic element for human survival and the guarantee for the development and progress of human society (Wang et al. 2019). Although water resources are renewable resources, they are limited to some extent. With the development of social economy and the advancement of industrialization, the water consumption has been increasing, and the limit of water use has appeared in many places, and even exceeded the limit of water use in some places (Zhang and Xu 2019). According to relevant statistics, the growth rate of the world population is 80 million every year, and the increase of water consumption is increasing at twice the rate. The form of water resources is very serious, so it is very This article is part of the Topical Collection on Geological Modeling and Geospatial Data Analysis * Na Li [email protected] 1

important to study the sustainable use of water resources (Wang et al. 2018). With the acceleration of China’s industrial and urban development, the form of water resources in China is very severe; coupled with the impact of human life on the climate, the use of water resources has undergone a very great change. In addition to the development and utilization conditions of cities, their quality, quantity, and spatial and temporal
