摘要
从水文地球化学的角度松嫩平原西部地表水和地下水的碱化特性进行了系统的探讨 ,并利用钠吸附比 (SAR)对该区各种水体的碱化特性进行了定量研究 ,湖泡水体SAR值最高 ,承压水SAR值最低。研究了溶液中离子对相互作用下各种水体的SAR值 ,根据统计结果建立了二者之间的相关关系。同时考虑到农业灌溉用水中碳酸平衡对土壤盐碱化的影响 ,探究了松嫩平原西部河流水、湖泡水、潜水和承压水的SAR。根据计算结果对松嫩平原西部地表水和地下水的农业灌溉特性进行了评价 ,提出了综合利用各种水体进行农业灌溉的可能性。该结果对半干旱的盐碱化地区农业用水灌溉具有指导意义。
Alkaline characteristics of surface water and ground water in the west of Songnen plain are studied systematically from the point of view of hydro-geovhemistry.By the Sodium Adsorption Ratio(SAR),alkaline charactieristics of surface weter and ground water in the Songnen Plain west are quantitatively analyzed and studied.The results show that the SAR of lakes is the highest,and that of confined waters is the lowest,Furthermore,Sodium Adsorption Ratio(SAR)affected by ions each other are researched,and on the foundation of statistics results,their relationships are founded, and on the foundation of statistics results,their relationships are founded. On the other hand taking into account carbonate and bicarbonate in agriculture irrugation water affecting on soil alkaline,we calculate and study SAR(ADJ) of surface and ground water in the west of Songnen Plain.At last,according to the calculation results,we appraise the agriculture irrigation charactiristics of surface and ground water in the west of Songnen plain,and put forward to the possibility of applying synthetically all kinds of water bodies during the course of semi-arid saline-alkaline region.
