摘　　要：以大兴安岭林区落叶松林地为研究对象,利用相关分析和通径分析方法,分析无降水条件下,落叶松林地表细小可燃物含水率变化与相对湿度、气温和风速间的相关关系和途径。结果表明:可燃物含水率变化与前2时刻的相对湿度、气温、前3时刻的风速相关性最大;可燃物含水率的变化受前1时刻含水率的直接影响最大,相对湿度次之,气温和风速的影响较小。We studied the correlation between surface fine moisture and temperature, relative humidity, wind speed of non-rain- fall larch forest in Daxing＇ an Mountain by using correlation analysis and path analysis. The correlation is the most maxi- mum between moisture and temperature before 2 h, relative humidity before 2 h, and wind speed before 3 h. The influence of moisture by that before 1 h is the greatest, followed by relative humidity, temperature and wind speed.
