摘要
农业用水在总用水量中的比例较大,开展农业节水的潜力巨大。利用邢台市2001-2012年用水量资料分析,农业用水占总用水量的76.41%,农业用水量呈下降趋势,而粮食产量却呈增加趋势。农业灌溉用水量减少的主要原因是开展农业节水措施,节水灌溉面积占总灌溉面积的28.8%。邢台市农业灌溉节水措施主要以低压管道输水措施,占总节水面积的98.5%。通过对农业用水结构变化特征分析,为合理开发利用水资源和节水型社会建设提供科学依据。
Agricultural water consumption in the total water use in the proportion of larger,the huge development potential of agricultural water saving. Utilization of 2001- 2012 in Xingtai,the water consumption data analysis,agricultural water use accounts for 76. 41% of the total water use,water use in agriculture decline,while food production is increased. The main reason of agricultural irrigation water use is to reduce the agricultural water saving measures of water- saving irrigation area,the totalirrigation area of 28. 8%. Mainly in the low pressure pipeline measures of agriculture irrigation water saving measures in Xingtai City,the total water area of 98. 5%. Through the analysis of agricultural water structure change characteristics,and provide scientific basis for water resources and water- saving society construction and rational development and utilization.
