【摘要】：水短缺严重制约城市经济社会的快速发展。本文基于2000-2012年间北京城市发展以及水资源利用等数据,采用灰色关联法分析工业、农业、生活和环境用水与城市化率、产业结构、经济发展水平、居民生活水平等城市发展指标之间的关联程度,探讨水资源利用结构随着城市发展的变化情况。结果表明:1产业结构调整对水资源利用总量变化的影响最大,关联度r2为0.83;城市化率和居民生活水平次之;经济发展水平最弱,关联度r3为0.62;2生活用水受到城市发展水平的影响最大,关联度r3为0.92;其次为农业和工业用水;环境用水量受城市发展水平影响最小,关联r4度为0.68;3城市发展过程中,生活用水的增加和人均GDP等经济因素以及人口规模相关,需采取相应措施,控制生活用水的持续增加,维持北京市用水总量的稳定。
[Abstract]:Water shortage seriously restricts the rapid development of urban economy and society.Based on the data of urban development and utilization of water resources in Beijing from 2000 to 2012, this paper analyzes the rate of urbanization, industrial structure and economic development of industry, agriculture, living and environmental water use and urbanization by using grey correlation method.The degree of correlation between urban development indicators such as residents' living standard is discussed, and the change of water resources utilization structure with urban development is discussed.The results show that the adjustment of industrial structure has the greatest influence on the change of total water resources utilization, the correlation degree R2 is 0.83, the urbanization rate and the living standard of residents are the second, and the level of economic development is the weakest.The correlation degree R3 is 0.62m2, and the correlation degree R3 is 0.92. the environmental water consumption is the least affected by the level of urban development, and the correlation R4 is 0.683 in the process of urban development.The increase of domestic water consumption is related to economic factors such as GDP per capita and population scale. It is necessary to take corresponding measures to control the continuous increase of domestic water use and to maintain the stability of the total amount of water used in Beijing.
