利用松嫩平原西部水体化学特征的测试数据 ,对其钠吸附比进行了系统的探讨 .总体上 ,湖泡水体SAR值最高 ,承压水SAR值最低 .研究了仅考虑溶液中Na+ 、Mg2 + 和Ca2 + 情况下的钠吸附比值 (SARP)及离子对相互作用条件下的钠吸附比值 (SART) ,据统计结果建立了其相关关系 .同时 ,探究了松嫩平原西部各种水体受碳酸平衡影响下的钠吸附比 (SARP (ADJ)和SAPT (ADJ) ) ,并对几种水体钠吸附比的计算方法进行对比 ,根据Richards ( 195 4)的分级标准和松嫩平原西部水体的实际情况 ,将之应用于地表水和地下水的灌溉特性评价 ,提出了适合于当地水体碱化特征评价的钠吸附比评价标准
Based on the test data of the chemical characteristics of the western Songnen Plain, the sodium adsorption ratio was systematically investigated.At the whole, the highest SAR value of the lake water body and the lowest SAR value of the confined water were studied.The results show that only the Na +, Mg2 + And the ratio of sodium adsorption (SARP) in the case of Ca2 + and the sodium adsorption ratio (SART) under the interaction of ion pairs, the correlation was established according to the statistical results.At the same time, (ADJ) and SAPT (ADJ) under different conditions were compared. According to the classification criteria of Richards (195 4) and the actual situation of western Songnen Plain , Applied it to the evaluation of irrigation characteristics of surface water and groundwater, and proposed the evaluation standard of sodium adsorption ratio which is suitable for the evaluation of alkalization characteristics of local water bodies
