摘要
研究系统地梳理了基于农田旱涝渍响应的区域水调控研究进展,探讨水分胁迫对农作物生长的影响,识别旱涝渍胁迫对农作物产量的影响机理,分析农田灌溉、排水系统及地下水位调节的现状和技术创新。大尺度上水调控已形成系统性研究成果,但未见综合考虑旱涝渍胁迫的农田区域水调控研究;对旱涝渍灾害形成了丰富的研究成果,但是未见统筹考虑农田区域水调控的旱涝渍灾害相关研究。根据灌溉技术、地下水管理策略、排水技术革新及数值模型的应用,讨论了相关技术在提高灌溉水利用效率方面的应用;提出了相应的未来研究方向,为实现农田稳产高产提供理论支撑。
The study systematically reviewed the research progress on regional water regulation based on farmland responses to drought,flood,and waterlogging.It explored the impact of water stress on crop growth,identified the mechanisms through which drought,flood,and waterlogging stress affect crop yield,and analyzed the current status and technological innovations in farmland irrigation,drainage systems,and groundwater level regulation.At a large scale,water regulation had yielded systematic research outcomes;however,studied on regional farmland water regulation that comprehensively consider drought,flood,and waterlogging stress were still lacking.Although abundant research had been conducted on drought,flood,and waterlogging disasters,there was a lack of studies that integrated these disasters with regional farmland water regulation in a coordinated manner.Based on irrigation technologies,groundwater management strategies,innovations in drainage techniques,and the application of numerical models,the study discussed the application of these technologies in improving irrigation water use efficiency.It also proposed corresponding future research directions to provide theoretical support for achieving stable and high agricultural yields.
