| 摘 要： | 对木麻黄沿海防护林的林内降水特征的研究表明 :惠安木麻黄沿海防护林的林外年降水总量为 2 0 0 1 1mm ,年穿透降水量为 16 0 9 4mm ,占林外年降水量的 80 4% ,年树干径流量为 171 7mm ,占林外降水量的 8 6 % ,年林冠截留量为2 2 4 0mm ,占年降水量的 11 2 %。穿透降水与降水量以及树干径流与降水量之间存在着明显的直线相关关系 ,可分别描述为 y =0 8972x - 4 4974和 y =0 10 5 4x 0 2 5 4。

| Abstract: | The study results reveal that the annual total rainfall amount is 2001.1mm outside the coastal protection forest of Casuarina equisetifolia in Hui’an,the annual penetrative rainfall amount is 1609.4mm,accounting for 80.4% of the annual rainfall amount outside the forest;the annual stemflow amount is 171.7mm,accounting for 8.6% of the annual rainfall amount outside the forest;the annual canopy interception amount is 224.0mm,accounting for 11.2% of the annual rainfall amount outside the forest;and there exists the evident linear correlation between the penetrative rainfall amount and the rainfall amount and between the stemflow amount and the rainfall amount,which may be described as y=0.8972x-4.4974 and y=0.1054x-0.254,respectively. |
