Study On Farmland Water Conservancy Construction In Wuyuan County(1950-1978)

Wuyuan County,located in the heart of Hetao Plain,is affiliated to Bayannaoermeng,Inner Mongolia Autonomous Region.The total land area is2492.9 square kilometers,accounting for 1/4 of the total area of Hetao Irrigation District.Wuyuan County with abundant water resources has a flat terrain,fertile soil.It is a typical irrigated agricultural area,and it is necessary to renovate the saline-alkali wasteland to expand the cultivated land area.Before the founding of New China,due to years of war and frequent natural disasters,farmland water conservancy was in disrepair all year round,and farmland water conservancy facilities in Wuyuan County were severely damaged,seriously restricting the development of agricultural production.After the peaceful uprising of Suiyuan on September 19,1949,the Communist Party of China took over Wuyuan County and established the people's regime.After the establishment of the new regime,faced with a situation where there is still a lot of waste,there is an urgent need to restore and develop production.In the case of serious shortage of human,material and technical power,the Wuyuan County People's Government decided to take the method of restoring the old water conservancy restore and develop agricultural production.This measure has achieved good results and laid the foundation for the recovery and development of the agricultural economy.With the consolidation of the people's political power,further development of agricultural production has become both a matter of urgency and feasible.Since 1953,in the face of backward water conservancy facilities,in order to resist severe drought,Wuyuan County has organized forces to adjust and expand canal systems at all levels.At the same time,Wuyuan country takes effective water-saving measures and drought-resistant irrigation according to local conditions.Therefore,the area and grain output have increased significantly.In 1958,with the establishment of the "three mains" water control policy and a comprehensive plan for the eradication of the Yellow River,the water conservancy construction in Wuyuan County entered a new period.At this stage,due to the gradual maturity of irrigation facilities,the irrigation area has expanded and the amount of water diversion has increased greatly,making the soil secondary salinization more and more serious.Drainage treatment has become the center of farmland water conservancy construction during this period,and Wuyuan County has begun large-scale reconstruction and expansion of irrigation and drainage projects.At this stage,compared with the past,farmland water conservancy construction is characterized by large investment,large scale,and high efficiency.Through three stages of farmland water conservancy construction in Wuyuan County,irrigation and drainage facilities have been basically improved,flood and drought disasters have been controlled,and gravity irrigation has gradually transitioned to planned regulation.The development of soil salinization has also gradually improved and make sure that the region economy and social undertakings develop stably.
