中文摘要	依据Q－型系统聚类分析方法，选取巴丹吉林沙漠湖泊水化学离子为变量，将研究区划分为A、B、C三个分带（区）。同时，利用遥感影像资料提取相应湖泊的面积信息，并进行等级划分，与湖泊水化学特性作对比分析，以探究二者的关系。结果表明：位于沙漠东南边缘的A类湖泊沿东北一西南向呈带状分布，以淡水湖和微咸水湖为主，湖泊面积极小；B类湖泊占据了腹地湖区的绝大部区域，沿西北一东南呈带状分布，以面积大，盐分高为主要特点，且与A湖泊带无交叉区域。C类湖泊数量少，分散在A、B湖泊带的边缘地带，但理化特征却不同于周边湖泊，极有可能是由局部地理环境造成的主要湖泊带周边的特例。聚类结果与面积分级的综合分析表明，沙漠南北湖区水化学与面积不完全相关。
英文摘要	Based on the data of hydro-chemical ions of the lakes in the Badain Jaran Desert, we divided the study area into A, B and C subareas with Q-mode hierarchical cluster method. Besides, lake area information was extracted from the latest RS images to make a further study on the relationship with lake hydro-chemistry data. The results showed that the lakes of type A were all located in the southeast of the desert with a form of northeast southwest belt, which included most of the lakes on the margin of the desert with lower total dissolved solids and least lake area. The type B lakes occupied most parts of the in land desert with a form of northwest-southeast belt. Remarkable differences in the physical-chemical characteristics were noticed in comparison of the two belts of A and B.A few lakes decentralized outside the A and B belts were classified into type C, for their physico chemical property was different from that in the vicinity as special cases of A and B belts, which may be related to the local geographic environment. We found that the effect factors are vitally different between southeast lakes and inland lakes based on the comprehensive analysis in quality and quantity of the lake water.
