【摘要】：禹門口引黃灌區(qū)作為山西省最大的灌區(qū),是運城、臨汾兩市農作物生產基地,對兩市乃至山西省經濟發(fā)展有重要的影響。由于灌區(qū)內水資源量與供水時空分布不均問題,影響著灌區(qū)內的農業(yè)生產,并阻礙著水資源的可持續(xù)利用。如何使得有限的水資源發(fā)揮最大效益已成為亟待研究的關鍵問題,作者針對禹門口引黃灌區(qū)水資源的合理配置做了如下研究。 本論文收集、調查了禹門口引黃灌區(qū)內10個子灌區(qū)的面積概況、現(xiàn)狀水源和灌溉工程設施的利用情況。分析了灌區(qū)內可供水資源的基本情況以及水庫概況,得出了主要用于農業(yè)灌溉的供水資源,并分析計算了灌區(qū)內農業(yè)灌溉需水量,對禹門口引黃灌區(qū)的水資源進行了供需平衡分析。結果表明灌區(qū)內水資源在總量上可以滿足農業(yè)灌溉需水要求。 針對禹門口引黃灌區(qū)的水資源供需矛盾進行水資源合理配置的分析研究。分別從水量和流量兩個方面對灌區(qū)內的水資源進行合理分配,對時空分配不均問題提出了具體的分配方案和解決灌區(qū)缺水問題的辦法,并闡述了水資源合理配置實施辦法的保障措施。 具體研究成果如下： (1)依據(jù)水資源供需平衡分析得出：禹門口引黃灌區(qū)灌溉需水量為6.4億m3,灌區(qū)內工業(yè)年用水量0.88億m3,沖沙年用水量0.3億m3,生態(tài)補水用水量0.45億m3,總計8.03億m3,而灌區(qū)年提水總量為8.5億m3。從水量平衡分析可知供水可以滿足需水要求。 (2)通過對灌區(qū)內蓄水量和農作物生育期灌溉缺水量矛盾分析,提出了具體的配置方案：將3月20日～3月25日(蓄水量0.09億m3)、4月15日～4月19日(蓄水量0.22億m3)、5月26日～5月31日(蓄水量0.09億m3)、6月1日～6月15日(蓄水量0.627億m3)、7月1日～7月12日(蓄水量0.182億m3)這五個余水期的蓄水量按需分配給3月26日～4月14日(缺水量0.038億m3)、4月20日～5月25日(缺水量0.27億m3)、8月1日～8月15日(缺水量0.627億m3)、11月21日～12月12日(缺水量0.27億m3)四個灌溉缺水期,由此可見,余水期的蓄水量可以滿足灌溉缺水期的缺水量,做到了合理分配水資源。 (3)通過灌區(qū)水資源在流量上的配置研究表明：在農作物四個生育期內(3月20日～3月25日、3月26日～4月14日、4月20日～5月25日、11月21日～12月12日)灌區(qū)所需灌溉流量都超過了50m3/s,因此利用灌區(qū)內水庫蓄水來滿足這四個生育期的灌溉流量要求。通過分析灌區(qū)內需要進行三次蓄水,第一次蓄水(3月20日～3月25日共蓄水900萬m3)和第二次蓄水(4月15日～4月19日共蓄水2200萬m3)可以直接蓄到三泉水庫、西梁水庫和澮河水庫；而第三次蓄水(5月26日～7月12日)總量為8990萬m3,而這三個水庫可調蓄的總庫容3825萬m3,所以建議新建一個調蓄庫容為5165萬m3的水庫。 采用水資源在水量和流量兩個方面的水資源配置方案,解決了灌區(qū)內由于水資源時空分布不均帶來的農業(yè)灌溉的水資源問題,對促進灌區(qū)內人們經濟生活水平的提高和水資源的可持續(xù)利用有重要的意義。
[Abstract]:As the largest irrigation area in Shanxi Province , Yumenkou Yellow River irrigation area is the largest irrigation area in Shanxi Province , which has an important influence on the economic development of the two cities and even Shanxi Province . Because of the uneven distribution of water resources and time - space distribution in the irrigation area , the sustainable utilization of water resources is hindered . How to make the limited water resources exert the greatest benefit has become the key problem to be studied . The author studies the rational allocation of water resources in the Yellow River irrigation area of Yumenkou . This paper collects and surveys the area profile , status quo water source and utilization of irrigation works at Yumenkou Yellow River irrigation area . The basic situation of the water supply resources in the irrigation area and the general situation of the reservoir are analyzed . The water supply resources mainly used in agricultural irrigation are analyzed . The water resources in the irrigation area are analyzed and calculated . The results show that the water resources in the irrigation area can meet the demand of irrigation water demand in agriculture . Based on the analysis of the rational allocation of water resources in the irrigation area of Yumenkou Yellow River , the rational distribution of water resources in the irrigation area is carried out from two aspects of water quantity and flow , the specific distribution scheme is put forward to solve the problem of uneven distribution of time and space and the water shortage problem in the irrigation area is solved , and the safeguard measures for the implementation of rational allocation of water resources are expounded . The results are as follows : ( 1 ) According to the analysis of the water supply and demand balance of water resources , the irrigation water requirement of Yumenkou Yellow River irrigation area is 640 million m3 , the annual water consumption in the irrigation area is 0.888 million m3 , the water consumption of the irrigation area is 0.300 million m3 , the water consumption of the ecological water supply is 0.445 million m3 , the total amount of the ecological water supply is 800 million m3 , and the total amount of water in the irrigation area is 850 million m3 . From the analysis of the water balance analysis , the water supply can meet the water requirement requirement . ( 2 ) Based on the analysis of the contradiction between the amount of water stored in the irrigation area and the irrigation water shortage during the growth period of the crops , the specific configuration scheme is put forward : the water storage capacity of the five remaining water periods from March 20 to March 25 ( water storage capacity is 0.900 million m3 ) , May 26 to May 31 ( water storage capacity is 0.billion m3 ) , from July 1 to December 15 ( water storage capacity is 0.275m m3 ) , from November 21 to December 12 ( water shortage is 0.727 million m3 ) , the water storage amount of the remaining water period can meet the water shortage period of the irrigation water shortage period , and the water resources can be reasonably distributed . ( 3 ) The irrigation flow rate of the irrigation area is more than 50m3 / s , and the irrigation flow rate of the irrigation area is more than 50m3 / s in the four growing periods of crops ( 20 - Mar - 25 , Mar . 26 - April 14 , April 20 - May 25 , Nov . 21 - Dec . 12 ) . The total volume of the third water storage ( from May 26 to July 12 ) is 890.9 million m3 , and the total volume of the third water storage ( May 26 - July 12 ) is 382.5 million m3 . Therefore , it is recommended to build a reservoir with a capacity of 516.5 million m3 . By adopting the water resource allocation scheme of water resources in two aspects of water quantity and flow rate , the problem of water resources of agricultural irrigation due to uneven distribution of water resources in the irrigation area is solved , and it is important to promote the improvement of people ' s economic living standard in the irrigation area and the sustainable utilization of water resources .
