| 摘 要： | 通过对塞罕坝林区9月至翌年6月中旬整个森林防火期枯草、落叶松枯落物、樟子松枯落物、落叶松嫩枝、樟子松嫩枝含水率的观测,研究了含水率随时间变化的动态规律;以当日气象因子中的温度、湿度与连续无降水日为自变量,利用多元统计的方法建立了3种可燃物类型的含水率回归方程,并编制了适合塞罕坝林区的森林火险预报系统.

| Abstract: | Based on the water content of grass,litter and 1a branches of Larix princinpis-rupprechtii forests and Pinus sylvestris forests from September 2007 to June 2008 in Saihanba forest area,the dynamics of water content with time was studied.The regression equations of water content in three finds of fuel with the air temperature and humidity as well as continues non rainfall dry days were established.Thus the system of forest-fire risk prediction was also suggested in this area. |
