水资源系统在长时间尺度下的综合水资源量不仅与天然来水相关,同时受下垫面及人类活动的影响较大,故长时间尺度综合水资源量变化的影响因素较多且与社会发展联系密切,但目前有关结合多个因素评估长时间尺度综合水资源量变化的研究尚未... 水资源系统在长时间尺度下的综合水资源量不仅与天然来水相关,同时受下垫面及人类活动的影响较大,故长时间尺度综合水资源量变化的影响因素较多且与社会发展联系密切,但目前有关结合多个因素评估长时间尺度综合水资源量变化的研究尚未达成共识。利用层次分析法分天然来水、综合用水、社会因素3个方面构建了包含10个指标的区域综合水资源量评估体系。以汉江上游流域为例进行计算,发现该流域综合水资源量年际间波动较大,但总体上呈现下降的趋势。将综合水资源量状态按照不同的得分区间划分为5种类型,并在此基础上对汉江上游流域综合水资源量的发展趋势进行分析,结果表明未来汉江上游流域综合水资源量短缺的风险较大,需采取合理的措施提高用水效率。 展开更多

Based on the synergetic development of new industrialization, rapid urbanization and agricultural modernization(IUAM), and from the viewpoint of interactive relationships between water resources and regional population, eco-environment, economy and society, the concepts of water resources intensity(WRI), water environment intensity(WEI), water resources relative efficiency(WRRE) and water environment relative efficiency(WERE) are defined with reference to energy intensity, resources efficiency and environment efficiency theory. On the basis of benchmarking theory, the quantitative characterization and evaluation method of "Three Red Lines"(the upper limit of water resources allocation, the baseline of utilization efficiency of water resources and the upper limit of sewage discharge) is proposed. According to these concepts and models, an empirical analysis of the Three Red Lines of water resources on the Chinese mainland between 2003 and 2012 was carried out. The results showed that total water consumption in eastern, central and western parts of China possesses "club convergence" characteristics, which means these areas have similar internal conditions appeared convergence in the development. Inter-provincial differences in water consumption continue to decrease, but the north–south differentiation characteristics in the eastern and central regions were still relatively obvious, while provincial differences in the eastern part were at a minimum and the central region had the largest. Water Resources Efficiency(WRE) of all four sectors in the Southwest rivers and Huaihe River basins were generally high. Industrial WRRE in the Songhua River, Yangtze River and Pearl River basins, agricultural WRRE in the Songhua River, Yellow River and northwestern river basins and domestic WRRE in the Liaohe River, Yangtze River and Pearl River basins were all low. Eco-environmental WRRE in the southeastern rivers and Yangtze River basins were low but showed an upward trend. Other river basins, except for the Northwestern rivers basin, had high eco-environmental WRRE with a downward trend. Western China, especially the northwestern part,had a low relative intensity of the water environment(WERI) and high integrated water environment management(IWEM) performance, but the relative intensities of the water resources(WRRI) were fairly high, and the comprehensive performance of integrated water resources management(IWRM) in these regions was low. In southern China, especially the southeastern part, the IWEM was fairly high, but the overall IWRM was lower. 展开更多
