Study on water footprint of main crop production in Jing-Jin-Ji Region
摘要
Abstract
Based on the water footprint theory of crop production,we analyzed the water tootprint ot 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 billionm3,blue water footprint was 176.03 billionms 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.关键词
