Long-term Trend of Reference Evapotranspiration in Liuyuankou Irrigation System and its Impacts on Irrigation Water Requirements

Abstract

Abstract: The long-term trend of reference evapotranspiration (ET₀) and it’s relationships with weather parameters and irrigation water use were analyzed, and the reasons and impacts of ET₀ trend were investigated. Daily meteorological data for the years of 1983-2003 of Liuyuankou Irrigation Area, Henan Province from Huibei Irrigation Experiment Station were collected, then daily, monthly and annual ET₀ were calculated using the FAO-56 Penman-Montieth model. Mann-Kendall tests were conducted to detect trends in ET₀ and corresponding meteorological parameters. The results show that in Liuyuankou Irrigation System, ET₀ decreased 50mm/a in the last two decades; decreasing ET₀ was caused mainly by decreasing sunshine hour firstly and wind speed secondly, increasing air temperature was not enough to counteract the impacts of the former two; annual ET₀ decrease was contributed by decrease in April, June, July and August; when there was no significant trend in rainfall, decreasing ET₀ resulted in decreasing trend in irrigation requirement, which was confirmed by reduced diverted irrigation water from Yellow River. Therefore, besides dissemination of water-saving irrigation techniques, reduced diverted irrigation water from Yellow River was partially contributed from the decreasing irrigation water requirements due to climate change.
