摘要:

选取黑河中游流域的张掖绿洲为研究区域,探索建立了2019—2020年黑河中游流域田间-灌区-流域尺度上的水资源账户。结果表明:(1)田间-灌区-流域尺度上的水资源利用效率不同,整体上呈递减趋势,田间尺度上过程性损耗与总损耗量之比为0.61~0.68,不同作物损耗表现有所差异,灌区尺度上过程性损耗与总损耗量之比为0.454,流域尺度上的过程性损耗与总损耗量之比为0.203。(2)田间-灌区-流域尺度上的水资源总体损耗比例不同,整体上呈递减趋势,田间尺度上总损耗与总入境量之比约为1.01,说明田间的可用水量已被损耗殆尽;灌区尺度上总损耗与总入境量之比约为0.887,说明灌区尺度上仍有10%左右的水量可供利用;流域尺度上总损耗与总入境量之比约为0.728,总损耗与可用水之比约为0.845,说明流域尺度上虽然尚有10%~15%的水资源可供开发利用,但可利用空间已在极值附近徘徊,水资源在灌区和流域层面存在进一步开发利用的可能性,这对于干旱区合理调控水资源、指导绿洲灌溉农业及生态保护具有重要意义。

Abstract:

This paper selected the Zhangye Oasis in the middle reaches of the Heihe River Basin as the research area and explored and established water resource accounts at the field-irrigation area-basin scales in the middle reaches of the Heihe River Basin from 2019 to 2020. The results showed that: (1) The water resource utilization efficiencies at the field, irrigation area,and basin scales were different, showing a decreasing trend on the whole. The ratio of process losses to total losses at the field scale was approximately 0.61-0.68. The performance of losses for different crops varied. The ratio of process losses to total losses at the irrigation area scale was approximately 0.454, and the ratio of process losses to total losses at the basin scale was approximately 0.203. (2) The overall water resource loss proportions at the field, irrigation area,and basin scales were different,showing a decreasing trend on the whole. The ratio of total losses to total inflow at the field scale was approximately 1.01, indicating that the available water in the fields had been almost completely consumed. The ratio of total losses to total inflow at the irrigation area scale was approximately 0.887, indicating that there was still about 10% of water available for utilization at the irrigation area scale. The ratio of total losses to total inflow at the basin scale was approximately 0.728, and the ratio of total losses to available water was approximately 0.845, indicating that although there was still 10%-15% of water resources available for development and utilization at the basin scale, the available space had also been hovering near the extreme value. The research results show that there is a possibility for further development and utilization of water resources at the levels of irrigation areas and river basins.It’s of great significance for the rational regulation and control of water resources in arid areas, as well as for guiding the irrigation agriculture of oases and ecological protection.
