| Abstract: |
| 【Objective】This paper analyzes the balance between supply and demand of regional water resources to provide basis for the rational distribution and management of regional water resources. 【Method】By analyzing the ooze irrigation area water resources supply and demand balance problems, using the quota method combined with the related development planning forecast lead ooze irrigation water supply and demand of 2018 and 2025 different situations, put forward the regional water resources supply and demand balance index (RWRI), could be divided into water surplus water resources supply and demand situation, balance of water resources, water resources shortage of three types, Furthermore, it is further divided into 9 kinds of conditions and analyzed and explained each condition, so as to evaluate the balance of water resources supply and demand in Yinqin irrigation area. 【Result】 Under the condition that the guarantee rate p=50%, RWRI of the irrigation areas in 2018 and 2025 are 1.06 and 0.92, respectively, which are in a state of water resource balance and can maintain normal production and life. Under the guarantee rate p=75% and p=90%, RWRI of the Irrigated area in 2018 were 1.71 and 2.56, respectively, belonging to the situation of high water shortage and extreme water shortage. In 2025, the situation would be improved, and RWRI were 1.29 and 1.45, respectively, belonging to the situation of mild water shortage and high water shortage. 【Conclusion】In the future, the supply and demand of water resources in the irrigation area of Qinhe River will be better than the present situation, but it still can not meet the water demand of each department in the dry year. |
