摘　　要：利用京津冀地区(2个直辖市、11个地级市)气象及农业基础数据,采用彭曼公式与CROPWAT软件相结合的计算方法,分析了2014年京津冀地区主要农作物的生产水足迹。结果表明:小麦在整个生长期需水量主要以蓝水足迹为主,玉米在整个生长期主要以绿水足迹为主;2014年京津冀地区主要农作物总的生产水足迹为437.03×108m3,其中绿水足迹为137.71×108m3,蓝水足迹为176.03×108m3,灰水足迹为123.30×108m3;从京津冀地区主要农作物总的生产水足迹空间格局上来看,沧州、保定、邯郸和石家庄地区的主要农作物生产水足迹较大,是水资源调控的主要地区。Based on the water footprint theory of crop production,we analyzed the water footprint of main crop production in 13 Jing-Jin-Ji regions(2 municipalities and 11 prefecture-level cities)in 2014.Meteorological and agricultural basic data was analyzed by combing the Penman equation with CROPWAT software.The results showed that:the water requirement of wheat in the whole growth period was mainly blue water footprint,but green water for maize in this area;The total water footprint for five crops production in the Jing-Jin-Ji Region in 2014 was 437.03 billion m3,of which green water footprint was 137.71 billion m3,blue water footprint was 176.03 billion m3 and grey water footprint was 123.30 billion m3;In terms of the spatial distribution of the total water footprint of these five crops in the Jing-Jin-Ji Region,we found that the main crop production of Cangzhou,Baoding,Handan,and Shijiazhuang major contribution to water footprint.
