Through synthesizing the methods of fire weather forecast home and abroad,and taking the peculiar conditions of the forest areas in Heilongjiang province into account,the feasibility of applying the fire danger forecasting scale to fire weather forecast on the basis of records of relevant meteorological factors was studied and reported in this paper.

本文综合了国内外的火险予报方法,结合我国小兴安岭具体情况,提出了利用火险予报尺,通过气象因子予报,间接作森林火险予报的方法。

This paper has treated the forest fire as a combustion system.The

森林火灾作为燃烧系统,和森林可燃物的数量,含水量以及分布状态有关,也和当时的蔓延速度和可燃物的燃烧速率有关。按照不同的要素,包括初始燃烧速率,蔓延速度和地表杂草枯枝落叶层单位面积上的负荷量,以确定林火强度。火爬坡时,蔓延速度增加,火强度相应地增加;相反,下坡火的蔓延速度减缓,火强度也相应地变小。根据计算结果,林火强度不超过1×10~3千瓦/米~2是低强度,这时1立方米内的可燃物被烧掉的数量不超过3公斤,地表杂草枯枝落叶层的可燃物数量(W_0)不超过2.5公斤。即便地表可燃物保持在2.5公斤以下,蔓延速度大于3米/分时,火强度均将超过1×10~3千瓦/米~2。地被物数量大,火蔓延速度也大的林型中将产生最大的火强度,这和过去的经验是完全符合的。

In the western part of Liaoning Province the topography is varied, the vegetation scarce,the soil barren,the erosion serious,and the climate extremely dry.The established large-area plantations there are only pure forests of Chinese Pine.These forests are always under the threat of insect pests,diseases and forest fire.Moreover,they are unstable in ecology and have little effect on soil amelioration and water conservation. At present,the urgent task in afforestation is to establish mixed forest of Chinese Pine by strenuous effort.There are many tree species which can be mixed with Chinese Pine,such as oak,larch,maple,Chinese Arbovital, ash,Siberian apricot,black locust,and many shrubs as well. The main problem in developing mixed forest is that the broad-leaf trees can not grow well at first becouse of the severe conditions of heat and light.There fore,Chinese Pine on Shrubs should be Planted Prior to or simultaneously with broad-leaf trees to provicle better ecological condi- tions for the ertablishment of mixed forest.A number of mixing types such as in rows,in belts,in patches or in irregular patterns can be chosen, according to the site and species available.

辽西地区地形起伏,植被稀少,水土流失严重,土壤瘠薄,气候异常干旱。这里造林面积较大的只是油松,油松纯林病虫害严重,火险性强,改土保水作用差,生态上不够稳定,目前造林的迫切问题是大力发展油松混交林。本文对辽西地区现有几种混交林类型进行了评价,并提出在营造油松混交林时,由于辽西燥热强光等恶劣自然条件的限制,使得阔叶树种初期不能生长,因此应在栽植阔叶树前或同时栽植油松和灌木,待生态条件有一定改善之后栽植阔叶树才可成林。混交方式根据立地条件与树种的不同可选择行混、带混、块混以及不规则的混交方式。
