图1. 植被含水量指标冠层含水量(CWC, g·m^-2)、叶片等量水厚度(EWT, g·cm^-2)和活体可燃物湿度(LFMC, g·cm^-2)之间的关系框图。DMC, 干物质含量(g·cm^-2); LAI, 叶面积指数; m_dry, 生物量干质量(g·m^-2); m_fresh, 生物量鲜质量(g·m^-2)。

Fig. 1. A diagram showing the relationship of vegetation water content indicators, canopy water content (CWC, g·m^-2), leaf equivalent water thickness (EWT, g·cm^-2) and live fuel moisture content (LFMC, g·cm^-2). DMC, dry matter content (g·cm^-2); LAI, leaf area index; m_dry, dry mass (g·m^-2); m_fresh, fresh mass (g·m^-2).
