Fire disaster occurs frequently in Australia. Each year, several large wildfires break out in forests, and induce severe economic loss and serious ecological impacts. It is therefore very imPOrtant for ecologists in Australia to research fire ecology and fire management.This paper focuses on the phenomenon of forest fire, characteristics of fuel, fire behaviour and its effect on environment, and ways to control and minimize the hazard of forest fire.

The paleoclimate effects of six asteroid impact events on the Earth happened in Cenozoic are studied by employing a energy-balance model. The result shows that when the dusts produced by these impacts entered the stratosphere, the average temperature of the Earth decrease to below 0℃, the disturbances caused by the impacts on temperature are last for about 30 years in maximum. It is first time that greenhouse effect of the carbon diozide produced by global fire and decomposition the died animals and plants is considered in modeling. However, at maximum, carbon dioxide produced by these two effects (global fire and decomposition of the died animals and plains) only makes an increase of 67% the atmospheric carbon dioxide, the greenhouse effect is so small that it can be negleted while compared with the effect of the antigreenhouse effect of the dusts. When the global carbon cycle is considered,these two effects on atmospheric carbon dioxide are last for 100 years.

对发生于新生代的6次巨大天体撞击作用(65Ma,34Ma,15Ma,2.4Ma,1.1Ma,0.7Ma)的气候效应进行的模拟表明,这6次巨大天体撞击作用产生的尘埃进入平流层后,可使全球平均温度下降至零度以下,降温效应持续时间最长可达30年之久。首次在模拟中考虑全球性森林大火产生的CO2和死亡生物分解生成的CO2的温室效应,研究表明这两种作用使大气中CO2增量最大仅达67%,其增温效应远远低于尘埃层产生的降温作用.但考虑全球碳循环,这两种作用对大气中CO2影响可达100年左右.
