【摘要】：通榆县位于吉林省西部,降雨少,旱灾、风灾十分严重,农业产量不高。通过实施“节水粮行动”,可以促进当地农村经济发展,提高农民收入,而且还确保当地的粮食安全和水资源安全。本文通过对通榆县“节水增粮行动”水资源论证方案进行研究,提出了该地区开发利用水资源的方针举措,对水资源的配置进行了调整和改良,达到了合理开发、有效保护水资源的目的,具有非常重要的实际意义。首先,本文对以往研究成果进行了调研,就研究区水资源开发利用状况进行了定性分析。然后,在参考相关技术文件并结合当地降雨量及土壤性质的基础上,采用定额法确定了需水量。同时,本文还参考了已有灌溉工程近几年的灌溉经验,对灌溉需水量进行了综合分析,确定了灌溉需水量。最后,根据地下水资源分区模型,计算出可采水量,确定了机井的布置方案。经分析计算,确定出的水资源保障方案如下:方案区设计取水量7584万m3,其中,新增面积取水3953.28万m3,改造面积取水3630.72万m3,改造面积较方案实施前节水6226.38万m3。由于改造面积大、节水多,方案实施后比实施前节水2273.10万m3,全县取用水总量可减少到15348.2万m3,地下水开发利用率可下降到36.9%,提高了通榆县地下水开发潜力。通过地表水、地下水联合供水,可保障通榆县“节水增粮行动”对水资源的需求,可以取得明显的环境效益和经济效益。
[Abstract]:Tongyu county is located in the west of Jilin Province, less rainfall, drought disaster is very serious, agricultural production is not high. Through the implementation of the "water-saving grain", can promote the development of the local rural economy, increase farmers' income, but also to ensure food security and water resources security. Through the local county of Tongyu "water saving increasing grain" study on water resources demonstration project, put forward the development and utilization of water resources in the area of policy initiatives, the allocation of water resources has been adjusted and improved, to rational development, effective protection of water resources, it has very important practical significance. Firstly, this paper has conducted a survey of the previous research results, a qualitative analysis on the development and utilization of water resources in the study area. Then, in reference to the relevant technical documents and combining the local rainfall and soil properties, water demand is determined by using the quota method. At the same time, this paper also With reference to the experience in recent years, the existing irrigation irrigation project, on irrigation water requirements are analyzed, the irrigation water requirement. Finally, according to the groundwater resource partition model, calculate the recoverable water, determine the layout of wells. Through analysis, the water resources protection program to determine the design scheme: take the water of 75 million 840 thousand M3, of which, the new area of the water area of 39 million 532 thousand and 800 m3, 36 million 307 thousand and 200 m3 water transformation, transformation of the area is the first implementation of the program of 62 million 263 thousand and 800 m3. due to the transformation of water-saving area, water saving, after the implementation of the program than before the implementation of section 22 million 731 thousand M3 water, the water quantity can be reduced to 153 million 482 thousand M3, groundwater utilization rate can be reduced to 36.9%, improve the development potential of Tongyu county. The groundwater surface water, groundwater supply, can guarantee Tongyu County "increased water-saving grain" demand for water resources, can obtain obvious Environmental and economic benefits.
