为分析湖南省水稻生产水资源的占用情况,采用水足迹方法研究了2002—2015年湖南省水稻生产水足迹;利用贡献率分析方法探究气象因子和生产要素对水稻水足迹的影响。结果表明:水稻水足迹在研究时段内整体呈现下降态势,年际变化呈现波动性上升期(2002—2005年)、快速下降期(2005—2009年)、缓慢下降期(2009—2015年)三个阶段性波动特征;灰水足迹最大,比例从69.03%下降到68.98%,蓝水足迹比例从14.21%下降到12.75%;绿水足迹从16.75%提高到18.26%;农机动力、化肥投入、成灾率是是水足迹的主要影响因素,其中农机动力起抑制作用,化肥投入、成灾率起促进作用。建议湖南水稻生产水足迹调控的措施主要为提高...

The water footprint of rice production in Hunan province was studied by using the water footprints as a measuring tool for analyzing water occupation from 2002 to 2015, and contribution rate analysis was applied to explore the effects of meteorological factors and production factors on rice water footprint. The results showed that the rice water footprint showed a downward trend in the study period, and the interannual variation showed obvious fluctuation characteristics, which could be divided into three stages: fluctuation rising stage (2002-2005), rapid decline stage (2005-2009), and slow d...
