建三江分局用水结构演变及其驱动机制研究
Study on Evolution and Its Driving Mechanism of Water Utilization Structure in Jiansanjiang Branch Bureau
摘要
Abstract
The rational determination and scientific prediction of water consumption structure are the basis for drawing up the plan of water resources development and utilization,and it is significant for achieving the appropriate allocation of regional water resources and coordinated development of social economy.Based on data from 1999 to 2010 achieved from water resources almanac of Jiansanjiang Agricultural Reclamation Region of Heilongjiang Province,discussion of development trend of water consumed structure of Jiansanjiang Branch Bureau was conducted by using information entropy.Meanwhile,the driving factors of water consumed structure were filtered by factor analysis,and the principal driving force which caused the change of water consumption structure was analyzed.The results indicated that agricultural water occupied the dominant position,and industrial and domestic water accounted for a small proportion in water consumption structure of Jiansanjiang Branch Bureau.Total water consumption changed faintly from 1999 to 2002,but continued to grow since 2003,at the same time,agricultural and domestic water increased with a small proportion,industrial water was basically stable.Overall information entropy of water utilization structure showed upward trend in the 12 years（1999—2010）.Factor analysis results represented socio-economic factor and natural environment factor is principal driving force of water utilization structure evolution in Jiansanjiang Branch Bureau.关键词
