| 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。

| Abstract: | 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. |
