The Research Of Surface Fuel Of Three Different Stand Types In The West Mountain Areas Of Henan Funiu Mountain

Forest fire is a natural disaster which is unexpected, destructively and is hardly to fight.Nearly topping the three nature disasters which are damage forest is the forest fire. Forestfire is a matter of forest resources, ecological safety, people’s lives and property safety. Tograsp the law of forest fire, forecasting forest fire accurately and timely is an importantbasic work of forestry to protect the forest resources and the development theforestry．Funiu mountain is the main forest distribution area in our province. Pinus, quercusand mixed wood are the main forest type in this area. This paper investigated and analyzedthe space-time change law of fuel loading, moisture content, forest factors, terrain andEnvironmental factors. The results are as blow:1. The relationship of combustion of forest and age, canopy density showed a positivecorrelation.2. Mixed forest and fire-insulated forest can decrease the combustion of forest.3. To reduce the risk of forest fires, the dead branches on the ground should be cleanedtimely before the canopy density of the young stand of Chinese pine.4. The fuel loading of Chinese pine and cork oak plantations would be reduced after thecanopy density, the surface fuel loading would be increased with the increasing of canopydensity in the mixed coniferous.5. The lower surface fuel loading was affected significantly by the elevation in the threecommunity types of forests, and was decreasing with the increasing of elevation.6.Age class and fuel loading of Pinus tabulaeformis on the upper,lower surface, moisturecontent of the lower fuel were significantly positively correlated, elevation and lower fuelloading of Pinus tabulaeformis were significantly negative correlated, canopy density andlower fuel loading of Pinus tabulaeformis were significantly positively correlated.7.Age class and fuel loads of cork oak plantations on the upper and lower surface were notsignificant correlated, age class, elevation and moisture content of the lower fuel of corkoak plantations were all significantly positively correlated.8. In the mixed forest, the correlation between the age class, the surface fuel loading andthe moisture content is not significant; the elevation has a strong negative relationship withthe upper fuel loading and is in great positive correlation to the moisture content of combustible on the subsurface. The canopy density and the upper fuel loading in the mixedconiferous have shown a significant positive correlativity.
