全球智慧灌溉技术发展态势研究

Abstract

随着科技和信息的快速发展，智慧灌溉技术被广泛应用。为了掌握全球智慧灌溉技术的发展态势。针对产学研一条链上的基础研究、工程研究和专利技术开展研究，选取Web of Science的SCI论文数据库、Scopus的EI论文数据库和Dervent Innovation的专利数据库进行分析。构建智慧灌溉领域的检索词集，分析表现力指数、竞争力指数以及研究热点和发展态势。研究表明，智慧灌溉领域已经形成相对稳定的全球布局，在感知、控制、决策和管理四大方向进行了战略布局，已经形成相对稳定的六大研究方向即干旱胁迫下的灌溉策略、田间试验与水肥效率、水土监测、智能灌溉系统、可持续发展与节水灌溉、水平衡与灌溉用水管理，两大技术方向即实时灌溉控制系统和方法、节水灌溉装置。未来智慧灌溉研究方向逐渐向可持续、规模化发展，在技术布局上秉持深度交叉融合。培育新业态、新模式，推动智慧灌溉向规模化、专业化、产业化、多元化全面升级，为维护国家粮食安全、全面推进乡村振兴注入新质动能。

The rapid advancement in science, technology, and information over the past decades has led to a wide application of intelligent irrigation technologies worldwide. Using the multi-faceted approach, we analyze the past trajectory and future perspective of intelligent irrigation technologies by depth-examination of theoretical and engineering research as well as the granted patent applications over the past decades. The data used in the analysis were based on the publications indexed by Science Citation Index of Web of Science and Engineering Index (EI) of Scopus, as well as granted patents indexed in Derwent Innovations. This paper focused on performance index, competitiveness, research hotspots, and developing trend of intelligent irrigation. The results show that intelligent irrigation has well steadily established worldwide in terms of its perception, control, decision-making and management. In addition, six research areas have emerged over the past decades: irrigation technologies under drought stress, field experiments and water and fertilizer use efficiency, monitoring soil and water, intelligent irrigation systems, sustainable development and water-saving irrigation, and water balance and irrigation water management. Technologically, there are two active research areas in intelligent irrigation: real-time irrigation control and developing water-saving intelligent irrigation devices. Looking ahead, research in intelligent irrigation is expected to be in sustainability and scalability, as well as its combinations with other technologies. It has potential to safeguard food security and revitalize rural regions worldwide.
