摘要
石嘴山市供水以引扬黄河水为主,地下水为辅,在不开辟新的水源的条件下,未来年供水总量很难超过12亿m3。石嘴山市若保持现有水资源利用模式,按照"十一五"规划实现工农业生产、工业新上项目、城市化和生态环境保护等目标测算,到2010年年需水量将达到14亿m3以上;即使将农业用水保持在2005年的水平,到2010年年需水量也达到13亿m3以上,水资源缺口将长期存在。需要开源节流,以提高水资源利用效率为突破口,建立节水型工农业体系和全面节水型社会,摆脱水资源对经济发展的硬约束。
The water supply of Shizuishan City depents mainly on Yellow River. If it did not develop new water source, the amount of water supply would be very difficult to surpass 1.2 ×10^9m^3 per a. If Shizuishan city maintained the existing utility pattern of water resources, the amount of water demands would be over 1.4 × 10^9m^3 per a in 2010. Even if it limited the agricultural water within 1 × 10^9m^3 per a, the total amount of water demands would be over 1.3 × 10^9m^3 per a in 2010. In order to reduce the resources supply - demand gap and get rid of the water resources restraint to economic development, the water - preservation industry and agriculture system and the comprehensive water- preservation society should be established in Shizuishan City.
