摘要
多矩形图解法(MRD)采用9个相邻的多矩形坐标系,分别代表9种地下水类型,它具有容纳大量地下水化学分析数据的功能。图解结果不但可以清楚地显示地下水中阴、阳离子含量的信息,而且也提供了更明晰、易懂的水化学类型的信息。本文简要地叙述了MRD法的原理,并应用该方法分析了塔里木盆地各流域地下水的水化学类型,结果表明:MRD法可以清晰地表征塔里木盆地地下水水化学类型的空间变化特征。
Multi-rectangular diagram （MRD） uses 9 adjacent multi-rectangles in which each rectangle represents a specific groundwater type. This diagram has the capability to accommodate a large number of data sets. The plotting method not only exhibits information about the cations and anions explicitly, but also provides a more lucid hydrochemical classification. The MRD has been used to classify chemical analyses of groundwater in the Tarim Basin. Using this graphical method, ground water types of calcium bicarbonate, magnesium bicarbonate, sodium bicarbonate, and sodium sulfate and sodium sulfate are differentiated. They are the most abundant ground water types in the Tarim Basin.
