Agricultural Water Structure System Based On Efficient Utilization Of Water Resources

The growing demand for water resources makes the contradiction between supply and demand of water resources become more and more serious,the relationship between water objects has gradually aroused people’s concern.The scientific and reasonable adjustment of water use structure can improve the efficient utilization of the water resources,to maintain the balance between supply and demand of water resources,and stimulating the local economy and ensuring the sustainable and stable development of the society.Hebei province is a lack of water resources of the provinces,agricultural overexploitation accounted for a large proportion of the overexploitation,so this paper mainly studies the establishment of agricultural water structure reasonable,guaranteeing the supply and demand balance of water quantity.This paper takes Guantao County of Hebei Province as an example to study.Guantao County of Hebei province belongs to water resources shortage area,Groundwater overdraft situation is grim,causing the underground water level to continue to decline,it has been a serious threat to regional water resources and water environment security,therefore,agricultural water conservation urgent needs to be strengthened.In view of the present situation problems of development and utilization of water resources in Guantao County,and the current contradiction between water supply and demand,studying on the establishment of the system of scientific and reasonable structure of agricultural water.This paper mainly includes the following research contents: Firstly,by summarizing the relevant research on the adjustment of water use structure at home and abroad,summarizing and sorting out the main production and ecological environment problems that need to be solved,the research progress of high efficient utilization of water resources is introduced,and the structure system of agricultural water use based on the efficient utilization of water resources is proposed;Secondly,taking Guantao County in Hebei Province as an example,introducing the basic situation of Guantao county’s natural environment and social economy region,and the current situation of Guantao County for the supply and use of water to do the analysis;Thirdly,we perform an irrigation contrast experiment.Making an comparison of irrigation water under different water sources and water saving measures.According to the experiment,we obtain the irrigation water of different water-saving measures;Fourthly,we forecast the water demanded for GuanTao and analyze the distributable water whatever it has definitized weight.According to the contradiction between supply and demand of water resources,some solutions was put forward.Fifthly,introducing the groundwater in Guantao County of Hebei province over mining comprehensive control project of the pressure recovery situation,combining with the contradiction between supply and demand in Guantao County,optimizing combination of water saving measures and allocating water,establishing the system of agricultural water structure based on efficient utilization of water resources,evaluating agricultural water structure system of pressure recovery effect,assessing the function of water allocation and water resources control system.Research results show after the establishment of a reasonable system of agricultural water use in Guantao County,meeting the crop water demand and not over exploitation of groundwater.The relevant research results of this paper can provide technical support for the future implementation of underground water underground hydraulic mining engineering,water resources allocation and integrated management of water resources in Guantao county.
