水资源短缺是制约北京农业可持续发展的关键因素。文章介绍了北京农业用水的基本情况,分析了农业用水效率和用水结构;在此基础上,采用灰色关联度分析法对近十年来农业产业结构对农业用水量的影响进行了定量分析,结果表明,种植业、林业、畜牧业、渔业对农业用水量的灰色关联度排序,从大到小依次为种植业>渔业>畜牧业>林业。因此,基于节水的目标对农业结构进行调整时,首先要考虑种植业,其次是渔业、畜牧业。
Water shortage is a key factor restricting Beijing’s agricultural sustainable development. This paper introduces the basic situation of agricultural water use in Beijing and analyzes the efficiency of agricultural water use and the structure of water use. On the basis of this, we use the gray relational analysis method to quantitatively analyze the influence of agricultural industrial structure on agricultural water consumption in the past decade. The results show that , Planting industry, forestry, animal husbandry, fishery, agricultural use of water gray relational order, descending order of crop farming> fishery> animal husbandry> forestry. Therefore, when adjusting the agricultural structure based on water-saving targets, we must first consider planting and planting, followed by fisheries and livestock husbandry.
