摘  要:
准确地分析、研究城市用水结构的演变规律,对于制定城市水资源规划以及水资源合理配置具有重要的指导意义。在对包头市近11年用水结构演变规律分析的基础上,引入信息熵理论对包头市用水结构的发展趋势进行了分析。结果表明:包头市用水结构的特点是以农业用水为主,而工业和生活用水所占比重较小。2000-2010年,包头市用水总量呈上升趋势,年均增加473.76万m3,农业用水量及其所占比重逐渐减小,从2000年的74 517.37万m3和75.31%分别减小到2010年的69 969万m3和67.48%;工业用水量及其所占比重则逐渐增加,从2000年的17 135万m3和17.32%分别增加到2010年的26 157万m3和25.23%;生活用水量增长缓慢,年均增加26.40万m3,其比重基本稳定,维持在7.48%左右。包头市用水结构的信息熵总体上呈现出增加的趋势,但增幅不明显,由2000年的0.71增加到2010年的0.80,说明包头市用水结构有较小的向无序化方向发展的趋势。用信息熵理论可以较好地分析城市用水结构的演变。

摘  要:
Accurate analysis and research of the evolution law of urban water consumption structure has important guiding significance to decide the planning and rational allocation of water resource of cities.Based on the analysis of the evolvement law of water consumption structure in Baotou city during near 11years,the development trend of water demand structure is analyzed by using information entropy theory.The result shows that the characteristics of water consumption structure of Baotou City is that agricultural water demand accounts the dominant position,while the industrial and domestic water consumption occupy for a small proportion.In 2000-2010year,the total water consumption presented a slight rise tendency with annual increase by 4,737.6thousand m3.Agricultural water consumption and its proportion decreased gradually from 745,173.7thousands m3 and 75.31%in 2000year to 699, 690thousands m3 and 67.48%in 2010year,respectively.While industrial water consumption and its proportion increased gradually from 171,350thousands m3 and 17.32%in 2000year to 261,570thousands m3 and 25.23%in 2010year,respectively.Domestic water consumption increased slowly with an annual 2,640thousands m3,while its proportion was basically stable,maintained at around 7.48%.The information entropy of water consumption structure in Baotou City have a increasing trend,but the amplification is not very notable,just increased from 0.71in 2000year to 0.80in 2010year.This indicates that the water consumption structure in Baotou city have a smaller development trend to disorder.The case study indicates that using information entropy theory can better analyze the evolution of water consumption structure.
