The Forest Regeneration and Fuel Load on the Burned Areas of Beijing Xishan Forest Farm

Abstract

Abstract: Based on the field investigation data,the post-fire forest regeneration and fuel load in Platycladus orientalis forest、Pinus tablaeformisforest forest、Robinia pseudoacacia forest and Fraxinus chinensis forest were studied in Beijing Xianshan Forest Farm.In which,the first two forests was burned in 2003 and the other two stands burned in 2006,also,the artificial regeneration mode was used in the first forest and the natural regeneration mode was used in other three stands,and the potential combustibility of regeneration forests was discussed.The results showed that the post-fire biodiversity index decreased,but the total fuel load increased in the Platycladus orientalis forest compared with the unburned site;on the contrary,the biodiversity index increased,and the total fuel load decreased in the other three forest types compared with the unburned sites.The accumulation of post-fire fuel load indicated the positive relation with the regeneration time;also,the flammable fuel load increased after burning,thus the potential combustibility is increased in the post-fire forest.

Key words: burned area, fuel load, regeneration mode, biodiversity index
