Surface Fuel Loads in the Low Mountain Coniferous Forest of Ming Tombs Forest Farm and Relevant Affecting Factors

Abstract

Abstract: Based on the stand factors,topography factors and surface fuel loads in 21 plots of the artificial Platycladus orientalis forest and Pinus tablaeformis forest of Beijing Ming Tombs Forest Farm,the correlation analysis between fuel load and influential factors was conducted. The results showed that,to the whole coniferous forest,the shrub fuel load had positive correlation with the height to branch and negative correlation with the density,the herb fuel load had positive correlation with the average DBH and the average height of trees,the 1h and 10h dead branch load had positive correlation with crown coverage,to the Pinus tablaeformis forest,the shrub fuel load had negative correlation with the average DBH,the 1h and 10h surface dead fuel load had positive correlation with the altitude and the average height of trees,to the Platycladus orientalis forest,the shrub fuel load had positive correlation with the average height of trees,the herb fuel load had positive correlation with the average DBH and the average height of trees,the 10h surface dead branch load had positive relation with crown coverage.These results provide scientific basis for the fuel management in the study area.

Key words: Ming Tombs Forest Farm, correlation analysis, fuel load, fuel management
