本研究通过构建农业水资源利用效率指标,采用超效率SBM模型对浙江省2010-2020年的农业用水效率进行了测度,并运用核密度估计法分析了农业用水效率的时空演变规律,最后运用地理探测器探析了农业用水效率的主要影响因素,为解决我国农业水资源短缺和水环境污染问题提供参考.结果表明:浙江省农业用水效率从2010年的1.153上升至2020年的1.661,年均增长3.71%,多年均值为1.535,始终处于有效利用状态,多年稳定性较强,且纯技术效率影响较大;浙北地区农业用水效率高于浙南地区,但地区差异逐步缩小;经济发展水平、政府对农业用水的重视程度、农业种植结构、水资源丰裕程度是影响浙江省农业用水效率空间分异的主要因素,同时农业用水效率的空间分异并不是单一因子作用的结果,而是在多种因子共同作用下非线性增强的结果.据此,浙江省需从提高农民收入水平、加大农业财政投入力度、推进节水灌溉技术、提高农户主体节水意识等方面着手进一步提升农业用水效率.
Spatial pattern and influencing factors of agricultural water use efficiency in water-rich areas:a case study in Zhejiang Province
In order to provide reference for solving the problems of agricultural water shortage and water environment pollution in Zhejiang,an agricultural water use efficiency index was constructed,and an ultra-efficiency SBM model was used to measure the agricultural water use efficiency in Zhejiang Province from 2010 to 2020.The kernel density estimation method was used to analyze the spatio-temporal evolution law of agricultural water use efficiency.Finally,the main influencing factors of agricultural water use efficiency were analyzed using a geographical detector.The agricultural water use efficiency in Zhejiang Province increased from 1.153 in 2010 to 1.661 in 2020,with an average annual growth of 3.71%and an average of 1.535 in recent years,which is always in a state of effective utilization.Over the years,the overall trend of fluctuation rose,stability was strong,and the influence of pure technical efficiency was great.Although the agricultural water use efficiency in northern Zhejiang is higher than that in southern Zhejiang,the regional differences are decreasing.Economic development level,the government's emphasis on agricultural water use,agricultural planting structure,and water resource abundance were the main factors influencing the spatial differentiation of agricultural water use efficiency in Zhejiang Province.At the same time,the spatial variation of agricultural water use efficiency is not the result of a single factor,but of the nonlinear enhancement under joint action of many factors.Therefore,Zhejiang Province needs to further promote the efficiency of agricultural water use by improving farmers'income level,increasing agricultural financial investment,promoting water-saving irrigation technology,and improving farmers'consciousness of water-saving.
