【摘要】：基于疏勒河中游绿洲不同生态环境需水量类型的计算,估算了流域绿洲生态环境需水规模。计算结果表明,疏勒河中游绿洲最大、最小和最适生态环境需水量分别为7.22×10~8 m~3、5.58×10~8 m~3和7.09×10~8 m~3,分别占疏勒河中游绿洲水资源总量(15.65×10~8 m~3)的46.4%、35.7%与45.3%。在不考虑河流输沙和考虑输沙需水量的情况下,疏勒河河流生态环境需水量分别为2.49×10~8 m~3和2.62×10~8 m~3。提出了基于水资源合理配置的生态需水调控与管理、节水型社会建设、信息化管理技术、法律法规和政策体系的水资源管理对策。
[Abstract]:Based on the calculation of different ecological environmental water demand types in the middle reaches of Shule River, the water demand scale of the oasis was estimated. The results show that the maximum, minimum and optimum ecological environmental water requirements of the middle reaches of Shule River are 7.22 脳 10 ~ (8) m ~ (3) and 7.09 脳 10 ~ (8) m ~ (3), respectively, accounting for 46.435.7% and 45.33% of the total water resources of the oasis in the middle reaches of Shule River (15.65 脳 10 ~ (8) m ~ (3). The ecological environmental water requirement of Shule river is 2.49 脳 10 ~ (8) m ~ (-3) and 2.62 脳 10 ~ (8) m ~ (3) respectively without considering the sediment transport and sediment demand of the river. The countermeasures of water resources management based on the rational allocation of water resources are put forward, such as the regulation and management of ecological water demand, the construction of water-saving society, the information management technology, the laws and regulations, and the policy system.
