浙江省用水趋势及影响因素分析

摘要

As water resources problem is more and more serious ,the accurate analysis of the water use trend and influencing factors of water is significant to the control of the total water and the most stringent water management.Through the analysis of water consumption from 2005 to 2014 in Zhejiang province by trend method and correlation analysis,get the following conclusion:the total water consumption gradually became less,farmland irrigation,industrial water,residential water is about 80.89%;Total water consumption and GDP, industrial water service and industrial added value negative correlation ,residential water and population is positive correlation with water,agricultural water presents the downward trend,and the proportion to drop,re-lated to the effective irrigation area ,precipitation.%随着水资源问题越来越严峻, 准确分析用水的趋势与影响因素, 对地区用水总量的控制及最严格水资源考核具有重要意义. 采用趋势法及相关分析对浙江省2005—2014年用水量进行简单的分析, 得到以下结论:总用水量整体上呈逐渐较少趋势, 农田灌溉、 工业用水、 居民生活, 三者之和约占80.89%; 总用水量与GDP、工业用水与工业增加值呈现负相关性, 生活用水与人口表现为正相关性, 农业用水呈现下降的趋势, 且所占比例下降, 与有效灌溉面积、 降水有关.
