【摘要】：水与能源之间有着复杂而密切的联系,两者之间的相互关系已成为国际社会关注的热点问题。论文通过能源耗水这一概念,试图探究能源生产与用水之间的内在关联,通过空间自相关分析和脱钩分析寻求其发展变化规律,以期为实现水与能源的可持续发展提供借鉴。结果表明:我国几类主要能源的耗水空间分布差异较大,且与能源自身的空间分布特征有相似之处。火电、水电和原煤耗水强度具有明显的空间集聚特征,H-H集聚区范围逐渐扩大,集聚程度不断增强,而原油和天然气耗水强度呈随机分布特征,无空间自相关性。全国范围内,各类能源耗水与总用水量和GDP之间的协调关系均呈不断恶化的趋势,能源耗水的增长速度在逐步超越经济发展和总用水量变化的速度,节水将是未来产能耗水研究领域中的重要方向。
[Abstract]:There is a complex and close relationship between water and energy. The relationship between water and energy has become a hot issue of international concern. This paper attempts to explore the inherent relationship between energy production and water use through the concept of energy consumption. The spatial autocorrelation analysis and decoupling analysis are used to find out the law of its development and change in order to provide reference for the sustainable development of water and energy. The results show that the spatial distribution of water consumption of several main energy sources in China is quite different. The characteristics of water consumption of thermal power, hydropower and raw coal have obvious characteristics of spatial agglomeration, and the range of H-H agglomeration area is gradually expanded, and the concentration degree is continuously enhanced, which is similar to the spatial distribution characteristics of energy itself, and the characteristics of water consumption of thermal power, hydropower and raw coal are obvious. However, the intensity of water consumption of crude oil and natural gas is randomly distributed, and there is no spatial autocorrelation. In the whole country, the coordination relationship between all kinds of energy consumption and total water consumption and GDP is deteriorating. The growth rate of energy consumption is gradually surpassing the speed of economic development and total water consumption. Water saving will be an important direction in the research field of water consumption in the future.
