用水结构变化主要驱动力因子灰色关联度分析

灰色系统关联度分析方法对样本数量、分布规律要求不高,计算量小,且量化结果与定性分析一致,具有广泛的实用性.以郑州市为例,将灰色系统关联度分析方法应用到用水结构变化的驱动力因子分析中去,量化各驱动力因子的影响度,结果表明工业重复利用率、灌溉面积、城镇化水平是郑州市工业、农业、生活三大用水部门的主要驱动力因子,并针对各驱动因子提出了相应的节水措施,为郑州市水资源可持续利用及节水型社会建设提供参考依据.

Grey Relational Degree Analysis on the Major Driving Forces of Water Use Structure

Grey relational degree analysis has its peculiar advantage,such as: low sample amount and distribution rule require,simple and efficient.Its results consist with qualitative analysis and it has been widely applied.In this paper it was used to analyze the driving forces of water use structure change,and zhengzhou city was selected as an example.Adopted grey relational degree analysis,the main factors were found out.Results showed that industry water utilization rate,irrigation area,urbanization level are the main driving forces,and corresponding water-saving measures were put forward.This study can provide reference for the construction of water-saving society and sustainable utilization of water resource.
