摘 要: | 在阐述水资源支持能力涵义的基础上,计算了关中地区生态需水量、75%保证率时可利用水量、75%保证率时总需水量以及水资源支持能力的供需平衡指数。结果表明:关中地区生态需水量2005年为43.699×10^8m^3,2010年为44.119×10^8m,2015年为44.394×10^8m^3;2005年75%保证率时可利用水量为49.885×10^8m^3,2010年为49.466×10^8m^3,2015年为49.190×10^8m^3;2005年75%保证率时总需水量为94.26×10^8m^3,2010年为86.63×10^8m^3,2015年为84.22×10^8m^3。最后计算水资源支持能力的供需平衡指数,2005、2010、2015年,供需平衡指数小于0,说明流域可供的水资源量不具备对这样规模的社会经济系统的支撑能力,流域水资源对应的人口及经济规模是不可承载的,供需平衡的差值主要靠侵占河道内的生态需水量来实现的,河道内的生态破坏就是很好的证据。

Abstract: | This paper firstly explicates the idea of regional Water resources supporting capacity, and then calculates the ecological water requirement, the available water resources, the total water demand and Index of Water Supply and Demand. By calculating, the ecological water requirement is 43. 699× 10^8 m^3 in 2005, 44. 119× 10^8 m^3 in 2010, and 44. 394× 10^8 m^3 in 2015 respectively, the available water resources is 49. 885 × 10^8 ma in 2005, 49. 466 × 10^8 ma in 2010, and 49. 190× 10^8 m^3 in 2015 respectively; 'the total water demand is 94. 26 × 10^8 m^3 in 2005, 86.63 × 10^8 m^3 in 2010, and 84. 22 × 10^8 m^3 in 2015 in Guangzhong region. Finally, the formula is applied to calculate the Ib in 2005, 2010 and 2015 which are negative so that the available water resources can not support Social economic system in Guangzhong region. The industry and agriculture demand for water resources mainly depended on using the ecological water in river leading to the damage of primitive ecological system in river. |
