【摘要】：[目的]以我国各省市2008~2015年农业水资源利用效率为研究对象,探究我国农业水资源利用效率的规律与特点,并基于此提出促进农业水资源合理利用的建议。[方法]主要采用了文献研究法、统计分析法和数据包络分析(DEA)法。通过文献搜集我国各省市2008~2015年与农业水资源利用相关的数据,构建DEA模型,对我国近年来农业水资源利用效率进行评价。[结果]2008~2015年,我国农业水资源利用效率在0.80上下浮动。各省市农业水资源利用效率随时间变化趋势不同。甘肃和上海的农业水资源利用效率涨幅最大,年增长率分别为4.39%和2.74%;山西、江西以及陕西省的农业水资源利用效率整体趋于下降;浙江、湖南以及陕西和新疆的农业水资源利用效率有先上升后下降的特点,表现出明显的波动。此外,农业水资源利用效率区域分化明显。东部地区农业水资源利用效率一般高于0.80,中部地区位于0.60~0.80,西部地区农业水资源利用效率一般低于0.60。[结论]2008~2015年,我国农业水资源利用效率表现出一定的时间差异性和空间差异性。时间差异性:我国农业水资源利用效率一直处于较高水平并呈现逐年增长趋势,不同省份的农业水资源利用效率随时间变动趋势各异。空间差异性:东部地区农业水资源利用效率最高,中东部地区农业水资源利用效率甚至达到了最优,中部地区其次,西部省区农业水资源利用效率最低。农业水资源利用效率受当地政策、经济发展水平、农业发展水平、水资源总量和人口压力等因素影响严重,今后应针对不同地区采取不同措施解决实际问题。
[Abstract]:[Objective] to study the utilization efficiency of agricultural water resources from 2008 to 2015 in various provinces and cities of China, and to explore the law and characteristics of the utilization efficiency of agricultural water resources in China. Based on this, some suggestions are put forward to promote the rational utilization of agricultural water resources. [Methods] the methods of literature research, statistical analysis and data envelopment analysis were used to collect the data related to the utilization of agricultural water resources from 2008 to 2015 in various provinces and cities of China. DEA model was constructed to evaluate the utilization efficiency of agricultural water resources in China in recent years. [Results] from 2008 to 2015. The utilization efficiency of agricultural water resources in China fluctuates around 0.80. The trend of agricultural water resources use efficiency varies with time in different provinces and cities. Gansu and Shanghai have the largest increase in agricultural water resources utilization efficiency. The annual growth rates were 4.39% and 2.74 respectively. In Shanxi, Jiangxi and Shaanxi provinces, the utilization efficiency of agricultural water resources tends to decrease as a whole; The utilization efficiency of agricultural water resources in Zhejiang, Hunan, Shaanxi and Xinjiang has the characteristics of rising first and then decreasing, showing obvious fluctuation. The regional differentiation of agricultural water resources utilization efficiency is obvious. The agricultural water resources utilization efficiency in the eastern region is generally higher than 0.80, and the central region is located at 0.60 ~ 0.80. The utilization efficiency of agricultural water resources in western China is generally less than 0.60. [Conclusion] from 2008 to 2015. The utilization efficiency of agricultural water resources in China shows a certain difference in time and space. Time difference: the utilization efficiency of agricultural water resources in China has been in a high level and showing a trend of increasing year by year. The agricultural water resource utilization efficiency of different provinces varies with time. Spatial difference: the eastern region agricultural water resources use efficiency is the highest, the central and eastern region agricultural water resources use efficiency even reaches the best. The utilization efficiency of agricultural water resources is affected by local policies, economic development level, agricultural development level, total amount of water resources and population pressure. In the future, different measures should be taken to solve practical problems in different regions.
