对设于松嫩平原嫩江右岸引嫩江水工程区域内的土壤水盐动态观测点多年研究结果表明，基 本无盐渍化的总干段土壤较通水前土壤盐分与ｐＨ值以及地下水ｐＨ值和盐分有减有增，但减多增少，说 明优质、低盐分嫩江水引入后土壤向改善方向发展，而土壤盐渍化重又无排水工程的莎分干段则相反，盐 渍加重重．北部引嫩江水工程是成功的，关键是必需有排水系统和排水出路．
The results of years of dynamic observation of soil water and salt in the Nenjiang River Nenjiang River right bank project located on the Songnen Plain show that the soil salt content and pH value of the soil without salinization and the pH value of groundwater and Salinity decreased but decreased more, indicating that high-quality, low-salt Nenjiang River after the introduction of soil to improve the direction of development, and soil salinization without drainage project Shacha dry segment is the opposite, salty heavier. The north of Nenjiang River project is successful, the key is the need to have a drainage system and drainage outlets.
