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 43.699×108 m3 in 2005, 44.119×108 m3 in 2010, and 44.394×108 m3 in 2015 respectively, the available water resources is 49.885×108 m3 in 2005, 49.466×108 m3 in 2010, and 49.190×108 m3 in 2015 respectively; the total water demand is 94.26×108 m3 in 2005, 86.63×108 m3 in 2010, and 84.22×108 m3 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.
