摘要:

西北干旱地区受监测资料匮乏等因素,难以实现区域尺度的水资源消耗效用评价。使用MODIS遥感数据驱动混合双源梯形蒸散发模型(HTEM),对焉耆盆地陆面蒸散发的时空过程进行了连续模拟,并对灌区耗水量进行有效性评价。结果表明:(1) 2013—2020年焉耆盆地灌区多年平均蒸散发为624.4 mm,其中作物生育期4—10月蒸散发占全年的89.6%。(2) 焉耆盆地灌区植被蒸腾与土壤蒸发多年平均分别为508.9 mm和115.5 mm,各占总蒸散发的81.5%和18.5%。(3) 焉耆盆地灌区多年平均蒸散发耗水量13.82×108 m3,其中高效、中效和低效耗水分别占总耗水量的81.5%、5.6%和12.9%,且耗水有效性与植被覆盖度密切相关。在区域尺度以时空连续的方式揭示了焉耆盆地灌区蒸散发水分消耗的有效性,可为干旱区水资源管控提供可靠的理论依据。

Abstract:

It is difficult to evaluate the water resource consumption effectiveness at a regional scale in the arid northwest due to the lack of monitoring information and other factors. This paper uses the MODIS remote sensing data to drive a hybrid dual-source trapezoidal evapotranspiration model (HTEM), to continuously simulate the spatiotemporal processes of land surface evapotranspiration in the Yanqi Basin of Xinjiang, China, and to evaluate the effectiveness of water consumption in irrigation areas. The following results were obtained: (1) The multiyear average evapotranspiration in the irrigation area of Yanqi Basin from 2013 to 2020 is 624.4 mm, of which the evapotranspiration from April to October during the crop fertility period accounts for 89.6% of the year. (2) The multiyear average of vegetation evapotranspiration and soil evaporation in the irrigation area is 508.9 mm and 115.5 mm, respectively, accounting for 81.5% and 18.5% of the total evapotranspiration. (3) The multiyear average evapotranspiration water consumption in the irrigation area was 13.82×108 m3, of which high-, medium-, and low-efficiency water consumption accounted for 81.5%, 5.6% and 12.9% of the total water consumption, respectively, and the effectiveness of water consumption was closely related to the vegetation cover. This study reveals the effectiveness of evapotranspiration water consumption in irrigation areas on a regional scale with a spatiotemporal continuum, which can provide a reliable theoretical basis for water resource control in arid zones.
