图6 错那湖流域沉积物不同粒级的轻矿物含量对比散点图 注：图中虚线上的数字表示矿物粗、细颗粒百分比相等的样品数量，虚线左边数字表示粗颗粒的百分比大于细颗粒的百分比的样品数量，虚线右边数字表示细颗粒的百分比大于粗颗粒的百分比的样品数量

Fig. 6 Comparative scatter plot of light mineral content of different grain classes in Co Nag Lake basin （The numbers on the dotted line in the figure indicate the number of samples with equal percentages of coarse and fine particles of minerals， the numbers on the left of the dotted line indicate the number of samples where the percentage of coarse particles is greater than the percentage of fine particles， and the numbers on the right of the dotted line represent the number of samples where the percentage of fine particles is greater than the percentage of coarse particles）
