| 摘 要： | 在北京西山林场建立侧柏、栓皮栎、黄栌、元宝枫和油松5种森林类型内建立观测点,从2008年12月至2009年9月,在各个类型内测定活可燃物和死可燃物含水率,并且建立可燃物含水率预测模型预测可燃物含水率。结果表明:1)可燃物含水率与气象要素中的温度、湿度、风速、降水量和连旱天数显著相关;2)可燃物含水率在每日变化呈现谷状,13:00—14:00达到每日最小值;3)可燃物含水率在1—3月初始值较低,4—6月活可燃物含水率急速增加,7—9月可燃物含水率基本达到一年内最大值。

| Abstract: | Observation points were set in 5 different types of forest including Platycladus orientalis forest,Quercus variabilis forest,Cotinus coggygria forest,Acer truncatum forest and Pinus tabulaeformis forest.Living fuel moisture and dead fuel moisture content of forests were measured from December 2008 to September 2009.Fuel moisture was used for establishing prediction model.The result showed that :(1) fuel moisture was significantly correlated with temperature,humidity,wind speed,precipitation and number of continuous drought days;(2) daily fuel moisture curve presents wave shape,with a trough in 13:00-14:00;(3) fuel moisture content is low between January and March but increases dramatically from April to June and reach the maximum of the year from July to September. |
