- 摘要：鲁西北地区是黄淮海平原中低产田低洼盐碱地的主要分布区之一.在鲁西北的禹城市具有该类型洼地十余万亩.应用基塘系统工程措施, 使浅层地下水地表化, 解决了洼地季节性积水、蒸发等形成的盐渍化问题, 同时洼地池塘养鱼改碱治水, 使原来偏微咸碱水质达到适合水产养殖高产稳产的水质条件, 改变了洼地原有的自然状况, 并且向良性转化.
- Abstract：The saline-alkali wetland is one of main type of lower yields in Huang-Huai-Hai Plain in China. According to the resource of water, quantity of heat and land, the saline-alkali wetland was integratly treated and utilized with the model of digging fish ponds and buiding raised fields. By regulating water and salt after engineering, the environment condition is better than ever. The monitoring results showed that soil organic matter was increased from 0.582%(1986) to 0.989%(1989), TN and TP contents were increased from 0.02% and 0.14%(1986) to 0.061% and 0.158% separately, and soil salt content was reduced from 0.50—0.29% to 0.06—0.29% year by year in the reformed land. By monitoring the moving of the salt and water, the results showed that the engineering solvs the question for preventing secondary saline-alkali of wetland.The integrated environment condition indicated that the original land condition is soundly transformed, the soil is fertilizing and the ponds are also developed from the barren pond to the fertile pond. All these prove that the planned goal of primary treatment and utilization has been achieved.
