一、概况阳谷县地处鲁西北黄泛平原,是一个老井灌区。五十年代开展了打砖井、下深泉,六十年代初开始机井建设,七十年代出现高潮,至今全县机井达到1万眼,平均103亩耕地一眼机井。共有排灌机械20817台,24.26万马力。随着井灌事业的发展,特别近几年连续大旱,地下水超量开采,漏斗面积逐年扩大,井灌出现了机井老化、单井涌水量减少、机井耗能高、装置效率低,灌溉成本高
I. Overview Yanggu County is located in the northwest of the Yellow River plain, is an old well irrigation area. In the 1950s, a series of well drilling operations were carried out, including Atsugi Well, Shimizu Shimomura, and well construction in the early 1960s. Since the seventies, a climax appeared. A total of 20817 irrigation and drainage machinery, 24.26 million horsepower. With the development of well irrigation, especially in recent years, continuous severe drought, over-exploitation of groundwater, funnel area expanded year by year, well irrigation wells withered aging, reduced single-well water inflow, shaft high energy consumption, low efficiency, high irrigation costs
