新疆吐鲁番地区用水结构变化及驱动力分析

Study on the Changes of Water Use Structure in Turpan Oasis and Its Driving Forces

引用信息熵计算模型,分析2004年~2014年吐鲁番地区工业、农业、生活用水和生态用水等用水结构的变化及其驱动力因子。结果表明,吐鲁番地区用水总量2004年~2009年上升较大,变化幅度也明显较大;2009年以后呈现缓慢上升的趋势,但整体年均增加0.364亿m^3;农业用水量及所占比重逐渐减小,工业用水量及所占比重呈现下降态势;生活用水量和生态用水量呈现继续快速增长趋势。

The changes and driving forces of water use structure of industry, agriculture, domestic and ecological water consumption in Turpan Prefecture in 2004-2014 are analyzed by using information entropy model. The results show that, （a） the total water consumption in Turpan Prefecture is significantly increased from 2004 to 2009 and slowly increased after 2009 with a annual increase of 36.4 million m3; （b） the proportion of agricultural water use is gradually reduced, the proportion of industrial water consumption appears a downward trend, but the domestic and ecological water use emerge continue and rapid growth trend.
