| 摘 要： | 针对河北省水资源日益紧缺、设施面积逐步扩大及其灌溉用水量增加等问题,本研究以河北省7个分区的设施农业典型种植模式为主要研究对象,对其灌水技术、灌水量及水分生产率进行分析计算,通过建立灰色GM(1,1)预测模型,预测2020年河北省日光温室发展面积为19.5万hm2,2030年为21.9万hm2。日光温室2020年灌溉需水量范围为62 006.3～68 694.7万m3,2030年为70 753.7～78 562.1万m3。

| Abstract: | To solve the problems of of water resource shortage,fast area-expanding in facility agriculture and the increasing of irrigation water in Hebei province,irrigation techniques,duty of water,and crop-water productivity were analyzed and calculated,taking the typical cropping patterns of facility agriculture in seven sub-areas with various cropping patterns in Hebei province as the research objects.Based on gray GM(1,1) prediction model,it predicated that solar greenhouse cropping area could be 19.5×104 hm2 in 2020 and 2.19×105 hm2 in 2030,and the duty of water could be 6.20 063×104～6.86 947×104 m3 in 2020 and 7.07 537×104～7.85 621×104 m3 in 2030. |
