广州市城市供水及用水量与气候因子的关系

针对中小尺度区域气象因素与城市供水、用水量之间的作用关系问题,选用了年均温度、年均湿度、年降水量和年日照时数等四个气象因子指标研究,广州市供水及用水量与各气象因子的关系进行了相关性分析,进一步分析了用水量对气候变化的敏感性,以及气候变化对用水量的影响趋势。结果表明,广州市供水及用水量与年均湿度、日照时数成负相关,而与年均温度、年降水量成正相关,生活用水对气候变化的敏感度大于生产用水,且气候变化对用水量的影响越来越显著。

The water supply and consumption responding to meteorologic change in Guangzhou city

The study on meteorologic change affecting the water consumption before was more concerned about water resource macroscopic allocates. Oppositely the study about meteorologic factor affecting the water consumption in middle and small-scale district are not so much. This paper intends to analysis water supply and consumption's response to the meteorologic change in Guangzhou city. It selects four meteorologic factors:the annually average temperature, humidity, precipitation and sunshine hours. It makes correlate analysis on water supply and consumption with each meteorologic factor. Also it analyzes water consumption's sensitivity to meteorologic changes. Finally it makes a tendency analysis about the meteorologic change's effect on the amount of water consumption. The study suggests that water supply and consumption have direct proportion relativity with the annually average humidity and sunshine hours, and have inverse proportion relativity with the annually average temperature and precipitation in Guangzhou city. The living water consumption's response to meteorologic change is more sensitive than that of productive water consumption. And the influence of meteorologic change on the amount of water consumption will be in an increasing tendency.
