图4. 属水平丰度热图
注：基于属水平微生物丰度的Z-score标准化热图及层次聚类分析。红色表示相对丰度较高，蓝色表示相对丰度较低；样本分为C2组（绿色）和N2组（紫色）。

Fig. 4. Heatmap of genus-level abundance
Note: Z-score scaled heatmap and hierarchical clustering analysis of genus-level microbial abundance. Red indicates higher relative abundance, while blue indicates lower relative abundance. Samples are divided into group C2 (green) and group N2 (purple).
