摘要
提高农业用水效率是缓解农业缺水、需水和用水问题的重要途径,也是影响农业经济发展以及全面小康社会建成的关键。采用水资源生态足迹模型,计算了2000-2014年中国农业用水生态足迹,利用Dagum基尼系数及其分解方法与Kernel密度方法实证考察了中国农业用水生态足迹的地区差异及演变趋势,并首次采用空间面板计量建模方法揭示了农业用水生态足迹的影响因素。研究发现:(1)中国农业用水生态足迹逐年降低,空间分布上,存在明显的地区差异,地区间差异是农业用水生态足迹总体地区差异的主要原因。(2)中国农业用水生态足迹存在较强的空间集聚特征。在诸多因素中,第一产业产值占比是影响中国农业用水生态足迹最重要的因素,人均水资源占有量和农业机械化程度对中国农业用水生态足迹有较显著影响。
Improving the using efficiency of agricultural water is an important way to alleviate water shortage, water requirement and water use, and also is the key to affect the agricuhural economic development and building a all-round well-off society. Using the ecological footprint model of water resources, we calculate China＇s 2000- 2014 ecological footprint of agricultural water use. Using Dagum ＂s Gini coefficient and its decomposition method as well as Kernel density method, this paper investigates the regional differences and ecological footprint of China＇s agricultural water use about the evolution trend. And using the spatial panel econometric modeling method for the first time,we reveal the influencing factors of ecological footprint of agricultural water use. The results show that： （ 1 ）The ecological footprint of agricultural water use in China is decreasing year by year. There are obvious regional differences in spatial distribu- tion, and regional differences are the main reasons for the differences of regional ecological footprint of agricultural water use. （2） There are strong spatial agglomeration characteristics of the ecological footprint of agricultural water use in China.Among the factors, the proportion of primary industry output is the most important one influencing the ecological footprint of agricultural water use in China. The per capita water resources and the degree of agricultural mechanization have a significant impact on the ecological footprint of agricultural water use in China.
