本文通过对“南水北调”后梁济运河沿线土壤可能产生次生盐渍化问题的调研与预测分析,认为:梁济运河沿线的洼坡、滨湖洼地为土壤次生盐渍化易发区;古湖洼地、滨河洼地、梁山县境内运河西部地区、东平湖二级湖区为轻度次生盐渍化和沼泽化威胁区.防治对策:尽量缩短高水位蓄水和输水时间;健全排水系统,增强排水能力,发展浅机井灌溉;发展暗管排水和台(条)田种植;开展水盐运动与水量平衡定位监测、预报工作等.
In this paper, through investigation and prediction of possible secondary salinization of soils along the Liangji Canal after the “South-to-North Water Diversion Project”, it is concluded that the depression along the Liangji Canal and the depressions along the lake are the areas prone to secondary salinization of soils ; Ancient lake depression, river depressions, western part of the canal within the territory of Liangshan County, Dongping Lake Lake area for the mild secondary salinization and swamp threat areas. Prevention and treatment measures: to minimize high water level impoundment and water delivery time; sound drainage System to enhance drainage capacity and develop shallow well irrigation; to develop concealed tube drainage and planted paddy fields; to carry out water and salt movement and water balance positioning and monitoring and forecasting work.
