摘要
为研究农业种植结构对水能利用的影响，以实现粮食增产、农民增收、农业节水节能的协调发展，对石家庄各县（市）2002年、2007年、2012年的农业种植结构以及农业用水和用能量的变化情况进行分析。结果表明：（1）石家庄市农业耗水大县主要集中在东部及东南部；西部及西南部的县（市）耗水量较少，同时农业能耗量呈现出与水耗量变化的相对一致性，这主要受西部地区地形所限，可耕地面积少，农业种植结构中除夏玉米、冬小麦外，谷子等低耗水的传统农作物仍较多，经济作物种植面积远小于东部县市；（2）2002~2012年石家庄各县（市）农业水能利用量变化表现出一定差异：其中，藁城、辛集、赞皇、平山、行唐、赵县、深泽、元氏、新乐和鹿泉10个县（市）呈现出水能变化的一致性；其余7县（市）及市区仍存在着水能变化不一致的现象。这主要是由各地的自然条件及其对农业种植结构的调整造成的。
The changes of agricultural planting structure,agricultural water and energy use in each county of Shijiazhuang City in 2002, 2007, 2012 were analyzed to study the impact of agricultural planting structure on water and energy use,in order to achieve the coordinated development of grain increase,in-come of farmers increase and agricultural water and energy saving. The results showed that the counties which consume larger amount of water are mainly located in the east and southeast, and other counties with less water consumption are located in the west and southwest of Shijiazhuang City. Meanwhile,agri-cultural energy consumption showed relatively consistent with the change in water consumption, which is mainly due to terrain constraints of western region,the small amount of arable land,agricultural planting structure in addition to maize,wheat,millet and other low water use of traditional crops still more,cash crops is far less than the eastern counties. Agricultural energy consumption changes from all counties of Shijiazhuang showed considerable differences,among them,Gaocheng,Xinji,Zanhuang,Pingshan,Xing-tang, Zhaoxian, Shenze, Yuanshi, Xinle and Luquan showed the consistency of the water and energy change. The remaining seven counties had the inconsistencies between water and energy. This is mainly due to the natural conditions of different counties and the adjustment of agricultural planting structure.
