| Abstract: |
| 【Background and objective】Agricultural irrigation is the main way of water consumption in arid and semi-arid areas of north China. The level of agricultural water-saving directly determines the amount of regional available water resources. In order to explore the level of agricultural water saving in the farming-pastoral ecotone in north China. 【Method】We take the farming-pastoral ecotone of Inner Mongolia as the research object. Based on the analysis of the current situation of agricultural water consumption, the comprehensive evaluation system of agricultural water-saving irrigation was established by combining the method of ahp and fuzzy comprehensive evaluation, considering the three aspects of agricultural water consumption, agricultural water-saving and agricultural output, and the comprehensive evaluation of agricultural water-saving level in the agro-pastoral transitional zone in 2020 was carried out. 【Result】The results showed that there was a great difference in agricultural irrigation water consumption among counties in the agro-pastoral ecotone of Inner Mongolia, and the overall trend was higher in the east than in the west. The irrigation water consumption ranged from 582.41 m3/hm2 to 4905.86 m3/hm2, and the utilization efficiency of irrigation water ranged from 51 to 84%. The comprehensive evaluation score of agricultural water-saving irrigation in all counties was between 2.19 and 4.13, and the overall water consumption level was above average. 【Conclusion】In 29 counties, excellent proportion was 3.4%, good proportion was 75.9%, and medium proportion was 20.7%. The areas with medium level of agricultural water-saving irrigation still need to develop water-saving measures to improve the utilization efficiency of agricultural water resources. |
