| 摘 要： | 为了清晰地描述冬小麦生产中耗水特征,基于水足迹理论和量化方法,分析了河南省小麦生产水足迹特征,并对造成水足迹区域差异的因素进行归因分析。结果表明:小麦生产水足迹的空间分布差异显著,其中豫西、豫中、豫南和豫北的小麦水足迹较高,而豫东地区的生产水足迹较低。豫南绿水足迹比例最高为34.5%,豫北绿水足迹最低为13.6%,绿水足迹所占比例呈现出从南向北递减的空间分布格局。归因分析结果显示,化肥、农机动力、降水量和平均气温是影响小麦水足迹空间差异的主要因素,且农业生产因子对水足迹的影响大于气象因子的。因此,提高农业生产效率和农业水资源利用效率,对河南省水资源的合理配置和高效利用有重要意义。

| Abstract: | In order to clearly describe the water consumption characteristics in production of winter wheat,in this paper,based on water footprint theory and quantitative methods,the characteristics of Henan wheat production water footprint were analyzed,factors causing water footprint regional differences were attribution analyzed.The results show that:the spatial distribution of wheat water footprint are significantly different,which are higher in west,central,south and north Henan,and low in east Henan regions.In south Henan green water footprint is the highest proportion of production 34.5%,the lowest in northern 13.6%,showing the from south to north decreasing spatial distribution pattern.The attribution analysis shows that fertilizers,farm power,rainfall and average temperature are the main factors influencing the distribution of wheat water footprint; and agricultural production factors on water footprint is larger than the meteorological factors.Therefore,improving the efficiency of agricultural production and utilization efficiency of agricultural water is significant to rational allocation and efficient utilization of water resources in Henan province. |
