北方地区城镇化和工业化进程与农业用水相关性区域分析

Regional analysis on correlations between urbanization and industrialization process and agricultural water use in North Area of China

以水资源紧缺的北方地区为研究对象,针对华北、东北和西北地区的社会经济发展特点以及资源禀赋选择河北、吉林和宁夏三个省,基于1997~2011年的统计数据,分析各省城镇化、工业化进程与农业用水的相关性。结果表明,各地的农业用水量和农业用水占总用水的比重随着城镇化和工业化发展呈下降趋势。在水资源紧缺的河北和宁夏,农业用水量与城镇化和工业化水平的相关性较好,而在水资源相对丰富的吉林,则该相关性较低。在经济发展水平相对发达的河北和吉林,农业用水比重与城镇化和工业化水平的相关性较好,而在经济水平相对较低的宁夏,则该相关性较低。研究成果可为北方地区农业用水量的平衡配置、合理调度等提供参考。

By taking the North Area of China that suffers water shortage as the study object,the three provinces,i.e.Hebei,Jilin and Ningxia are selected in accordance with the characteristics of the socio-economic developments and the endowments of resources in the regions of the North China,the North East China and the North West China,and then the correlations between urbanization and industrialization process and agricultural water use in all the provinces are analyzed on the basis of the relevant statistic data of 1997 ~ 2011.The result shows that the agricultural water use and its proportion in the total water use within all the regions concerned present the decreasing trends along with the developments of the urbanization and industrialization therein.In Hebei and Ningxia those suffer water shortage,the correlations between urbanization and industrialization process and agricultural water use are better,while the correlation is relatively lower in Jilin that is relatively rich in water resources.Furthermore,in Hebei and Jilin those are on relatively developed economic development level,the correlations between urbanization and industrialization process and the proportion of the agricultural water use are better,while the correlations are relatively lower in Ningxia that is on a relatively lower economic development level.The research results can provide a reference for balance allocation and reasonable scheduling,i.e.of agricultural water use.
