根据关中中部农灌用水的现状及存在的问题 ,对农灌水高效利用可行性进行了分析。分析认为 :关中中部地区水资源不足且农灌水占总用水比例大 ,因此必须走高效利用的路子 ;关中中部两个重要的城市 (西安、咸阳 )市郊经济发达 ,具备采用先进灌溉技术的条件 ,也有辐射影响的作用 ;渭北塬区地下水开发困难 ,在地表水灌区 ,节水的关键在于提高渠系水利用系数 ,在非地表水灌区应采用先进的节水灌溉技术 ;在河流阶地区 ,应发展高精尖农业 ,采用先进的灌溉技术以井水灌溉为主 ,优化水资源配置
According to the status and existing problems of irrigation and drinking water in central Guanzhong area, the feasibility of efficient irrigation and utilization of irrigation is analyzed. According to the analysis, the central and southern part of Guanzhong area is short of water resources and agricultural irrigation accounts for a large proportion of the total water consumption, so it is necessary to take the road of efficient use. In the suburbs of central and southern Shaanxi, Xi’an and Xianyang have economically developed suburbs and advanced irrigation technologies, But also has the effect of radiation; the groundwater exploitation in Weibei area is difficult. In the surface water irrigation area, the key of water saving is to improve the water utilization coefficient of the canal system. In the non-surface water irrigation area, advanced water- Should develop sophisticated agriculture, the use of advanced irrigation technology to well-water irrigation, optimizing water resources allocation
