分析了2001-2010近10年来陕西省工农业用水、生活用水以及生态用水的结构变化,并引入信息熵的方法对用水结构的演变趋势进行了探讨,同时阐述了造成这些变化的主要驱动因子。分析表明:陕西省用水总量近十年来在波动中缓慢上升,年均增加0.61亿m3;农业用水量和比重都在下降;工业用水总量变化较缓;生活用水和生态用水呈持续增长趋势。
This paper analyzed the change of water use structure,included industrial,agricultural,domestic and ecological water consumption from 2001 to 2010 in Shaanxi Province.Information entropy was introduced to discuss the trend of water use structure evolvement.Furthermore,the major driving forces of the change were analyzed.Results manifested that water consumption slowly grew in the last 10 years,with an annual increase of 61 million m3,the proportion of agriculture water use gradually decreased,industrial water consumption changed slowly,and the proportion of domestic and ecological water use obviously increased.
