Abstract: Based on 3 687 related literatures on agricultural irrigation water value included in the WoS database from 2000 to 2021, this paper uses CiteSpace software to draw a knowledge map of global irrigation water value research, and analyzes the number of published papers, authors, distribution of countries, journals and institutions, research hotspots and development trends of irrigation water value research at home and abroad. The research results showed that from 2000 to 2021, the number of papers issued in the field of irrigation water value showed an overall upward trend; the core authors and teams of the papers were mainly from China and America; the research forces were mainly distributed in China, America, Spain and other countries; the Chinese Academy of Sciences, China Agricultural University, Tehran University and other institutional contributions were out standing; the price of irrigation water and the utilization efficiency of water resources had always been the hot topics of research; from the perspective of development trends, the multidimensional evaluation of irrigation water value and the temporal and spatial dynamic characteristics of irrigation water value were the focus of future research; multisource spatiotemporal data sources and the integration and optimization of various pricing methods combined with computer artificial intelligence technology have become a new trend in the research of irrigation water value.
