【摘要】：水资源的合理利用对区域经济社会发展,及促进人与自然的可持续发展至关重要.以2004年~2015年中国31个省级行政单元为研究对象,利用重心分析模型测度其时序移动轨迹,并对水资源利用类型的结构变化进行探析,在此基础上,探究我国各省份的水资源利用效率的时空变化特征.研究表明:我国水资源总量的重心移动轨迹有很大的不稳定性,而水资源用量的重心移动轨迹大致呈"Z"型变化;生态用水和工业用水的空间变化差异最大,农业用水和生活用水空间变化差异较小;用水总量的变化差异和农业用水的变化差异空间分布基本一致;我国水资源利用效率基本上呈现出东高西低的阶梯状格局.
[Abstract]:The rational utilization of water resources is very important to the development of regional economy and society and to the sustainable development of man and nature. Taking 31 provincial administrative units in China from 2004 to 2015 as the research object, this paper uses the gravity center analysis model to measure its time series moving track, and probes into the structural changes of water resources utilization types. This paper explores the temporal and spatial characteristics of water resource utilization efficiency in various provinces of China. The results show that the trajectory of center of gravity movement of total water resources in China is very unstable, while the trajectory of gravity center movement of water resource consumption is approximately "Z" type, and the spatial variation of ecological water use and industrial water use is the greatest. The spatial variation of agricultural water use and domestic water use is small, the spatial distribution of the variation of total water use and agricultural water use is basically the same, and the water resources utilization efficiency of our country basically presents the ladder pattern of east high and west low.
