云南省水资源利用的时空变化特征与区域差异分析

Analysis on the Characteristic of Water Resources Utilization and Regional Differences in Yunnan Province

利用2007~2011年水资源拥有量数据、水资源消耗量数据和用水结构数据对水资源利用的时间变化特征与空间差异特征进行分析。研究表明：从水资源供需看,水资源拥有量的减少明显大于水资源消耗量的减少,水资源供需状况不容乐观;从水资源利用的时间变化特征看,水资源利用结构以农业用水为主,但工业用水比重与生活用水比重呈上升趋势,二者在水资源利用结构中的比重将继续增大;从水资源利用的空间差异特征看,怒江与迪庆水资源利用相对变化率最大,玉溪与昆明水资源利用相对变化率最小。

According to the water resources data and water utilization structure data analyze the characteristic of water resources utilization and regional differences during the period from 2007 to2011.Research shows：from the water resources supply and demand to see,reduction of water resources supply significantly greater than water demand reduce,water supply and demand situation is not optimistic.From the change characteristics of water resources utilization to see,the main water use structure is agricultural water,however,the proportion of industrial water and living water is rising,and both of the proportion in water resources structure will continue to increase.From the space differences of water resources utilization to see,the maximum change of relative rate is Nujiang and Diqing,and the minimum change of relative rate is Yuxi and Kunming.
