黄河三角洲盐碱地灌排工程改良技术参数的采集及建议

Acquisition and Suggestion of Technical Parameters for Irrigation and Drainage Projects of Saline Alkali Soil in the Yellow River Delta

摘要: 为了更有效地对黄河三角洲未开发利用的盐碱荒地实施灌排工程改良，本文对东营市利津县汀罗镇未开发利用的盐碱荒地进行数据采集。结果表明：该区域土壤质地多为砂土或砂壤土，土层深度为0.8~2.6 m之间，土壤渗透系数0.03~0.81 m∙d⁻¹之间，均为半透水性土壤，土壤入渗率介于0.7~1.23 mm∙min⁻¹，土层稳定性好，地下水埋深介于1.2~2.4 m之间，大部分浅于当地地下水临界深度。

Abstract: In order to improve the irrigation and drainage engineering of the saline-alkali wasteland in the Yellow River Delta more effectively, data were collected from saline alkali wasteland which was not exploited in Tingluo Town, Lijin County, Dongying City. The results show that the soil texture in this area is mostly sand or sandy loam soil, soil depth is between 0.8 - 2.6 m, the soil permeability coefficient is between 0.03 - 0.81 m∙d⁻¹, the soil is semi permeable, and the infiltration rate is between 0.7 - 1.23 mm∙min⁻¹ and the soil stability is good. The groundwater depth is between 1.2 - 2.4 m, most of which is shallower than critical depth of groundwater.
