| 摘要: |
| 在北方干旱半干旱地区,农业灌溉是水资源消耗的主要途径,农业节水水平的高低,直接决定着区域可利用水资源量。为探究我国北方农牧交错带农业节水的综合水平,以内蒙古农牧交错带农业节水灌溉为研究对象,在综合分析农牧交错带农业灌溉用水现状的基础上,通过模糊综合评价和层次分析相结合的方法,构建农牧交错的农业节水灌溉综合评价体系,对2020年内蒙古农牧交错带农业节水灌溉进行综合评价。结果显示：内蒙古农牧交错带各旗县间农业灌溉用水量相差较大,整体呈现东高西地趋势,灌溉水量在582.41～4905.86 m3/hm2之间,灌溉水利用效率51～84%；各旗县农业节水灌溉综合评价得分在2.19～4.13之间,用水水平整体处于中等偏上,29个旗县中优秀比例为3.4%,良好比例为75.9%,中等比例为20.7%。农业节水灌溉处于中等偏下水平旗县地区,需加大力度发展农业节水措施,提升农业水资源利用效率。 |

| 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. |
