  3. Beginning with the analyse of present situation and cause of formation of saline - alkali land, the irrigated area overall water salt trends are analysed, and the irrigated area saline - alkali land and the groundwater level and distribution law of groundwater degree of mineralization are expounded, the trendence of irrigated area saline - alkali land is put forward. then water salt balance model is estanbished according to the relationship of irrigating and drainage. regarding the irrigated area as a balance area, by analysis of mineralization degree of water pumping from the yellow river and drained off water from irrigated area, the change of the draining off water ion is forcasted in water reducing condition

    課題研究主要從鹽堿地現狀與成因及灌區總體水鹽動態分析兩方面入手，闡述了灌區鹽堿地、地下水位、地下水礦化度的分佈規律，分析了灌區鹽堿地的成因及變化趨勢；根據灌區灌溉、排水條件與以上各種因素的關系，建立了灌區水鹽均衡模型；把灌區作為一個均衡區，通過對黃河來水礦化度、灌區排水礦化度的分析，預測了在灌溉引水、排水減少時排水離子量的變化；運用灌區水鹽動態模型原理，對灌區現狀（ 1998 、 2000年）與規劃水平年總體水鹽平衡進行了計算；總結分析了灌區水鹽動態變化趨勢，計算並提出了排水控制標準。
