【摘要】：提高農(nóng)業(yè)用水效率是緩解農(nóng)業(yè)缺水、需水和用水問題的重要途徑,也是影響農(nóng)業(yè)經(jīng)濟(jì)發(fā)展以及全面小康社會(huì)建成的關(guān)鍵。采用水資源生態(tài)足跡模型,計(jì)算了2000-2014年中國農(nóng)業(yè)用水生態(tài)足跡,利用Dagum基尼系數(shù)及其分解方法與Kernel密度方法實(shí)證考察了中國農(nóng)業(yè)用水生態(tài)足跡的地區(qū)差異及演變趨勢(shì),并首次采用空間面板計(jì)量建模方法揭示了農(nóng)業(yè)用水生態(tài)足跡的影響因素。研究發(fā)現(xiàn):(1)中國農(nóng)業(yè)用水生態(tài)足跡逐年降低,空間分布上,存在明顯的地區(qū)差異,地區(qū)間差異是農(nóng)業(yè)用水生態(tài)足跡總體地區(qū)差異的主要原因。(2)中國農(nóng)業(yè)用水生態(tài)足跡存在較強(qiáng)的空間集聚特征。在諸多因素中,第一產(chǎn)業(yè)產(chǎn)值占比是影響中國農(nóng)業(yè)用水生態(tài)足跡最重要的因素,人均水資源占有量和農(nóng)業(yè)機(jī)械化程度對(duì)中國農(nóng)業(yè)用水生態(tài)足跡有較顯著影響。
[Abstract]:Improving the efficiency of agricultural water use is an important way to alleviate the problems of water shortage, water demand and water use in agriculture. It is also the key to the development of agricultural economy and the establishment of a well-off society in an all-round way. The ecological footprint of agricultural water in China from 2000 to 2014 was calculated by using the water resources ecological footprint model. The regional differences and evolution trends of the ecological footprint of agricultural water use in China were investigated by using the Dagum Gini coefficient and its decomposition method and Kernel density method. For the first time, spatial panel metrological modeling method was used to 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, and there are obvious regional differences in spatial distribution. Regional differences are the main reasons for the overall regional differences in the ecological footprint of agricultural water use. (2) there are strong spatial agglomeration characteristics of ecological footprint of agricultural water use in China. Among the many factors, the proportion of the output value of the primary industry is the most important factor affecting the ecological footprint of agricultural water use in China, and the amount of water resources per capita and the degree of agricultural mechanization have a significant impact on the ecological footprint of agricultural water use in China.
