摘要
用水结构的合理确定与科学预测是制定水资源开发利用规划的前提和基础,对于实现区域水资源合理配置、社会经济协调发展具有重要意义。在对关中地区近20年用水结构演变规律分析的基础上,引入信息熵的方法对关中地区用水结构发展的趋势进行了探讨;利用SPSS软件的主成分分析法对用水结构的影响因子进行筛选,分析了用水结构变化的驱动力因子。
The rational determination and scientific forecast of water consumption structure is the founda- tion of water resources utilization and planning. It has great significance for carrying out regional water resources reasonable allocation and social economy moderate development. Based on the evolvement regula- tion of water consumed structure in Guanzhong region in about 20 years lately, information entropy was introduced to discuss the trendof water consumed structure evolvement in this paper. Influence factors of the gross water consumed quantity in Guanzhong region were selected by using the software SPSS, and then the main driving forces resulted in variety of water consumed structure were clarified.
