摘要
利用河北省2010-2016年的用水量数据资料,分析了7年来农业、工业、生活和人工生态与环境补水用水量的变化情况。结果显示:7年来河北省总用水量总体呈下降趋势。农业用水量及其所占比重均逐年降低,工业用水量及其所占比重呈波动增长趋势,生活用水量及其所占比重逐年增长,人工生态与环境补水量及其所占比重逐年增长。研究表明:耕地面积的持续减少直接导致农业用水量的减少;工业用水量随着工业增加值的增加而增加,工业万元增加值用水量的减少对提高工业用水效率具有推动作用;人口增长是生活用水逐年增加的主要原因;对生态环境的高度重视及一系列政策的实施是生态环境用水增长的重要原因。
Using the data of water consumption in Hebei Province from 2010 to 2016,the changes of water consumption in agriculture,industry,living and artificial ecology and environmental hydration in the past seven years were analyzed. The results show that the total water consumption in Hebei Province has generally declined in the past seven years. The amount of agricultural water consumption and its proportion have been decreasing year by year. The industrial water consumption and its proportion have fluctuated. The domestic water consumption and its proportion have increased year by year. The artificial ecological and environmental water replenishment and its proportion have increased year by year. Studies have shown that the continuous reduction of cultivated land area directly leads to the reduction of agricultural water consumption;industrial water consumption increases with the increase of industrial added value,and the reduction of industrial water consumption by 10,000 yuan increases the promotion of industrial water use efficiency;population growth is The main reason for the increase in domestic water consumption year by year;the high attention to the ecological environment and the implementation of a series of policies are important reasons for the growth of water use in the ecological environment.
