摘要/Abstract

摘要： 对北京十三陵林场人工油松林和侧柏林进行踏查,并根据地型、林分因子的差异性设置21块样地,调查样地的林分、地型因子及可燃物负荷量,进行可燃物负荷量及其影响因子的相关性分析。研究结果表明:对针叶林整体而言,灌木可燃物负荷量与枝下高呈正相关,与林分密度呈负相关,草本可燃物负荷量与平均胸径、平均树高呈正相关,1h,10h时滞枯枝负荷量与郁闭度呈正相关;对油松林而言,灌木可燃物负荷量与平均胸径呈负相关,1h,10h时滞枯枝负荷量与海拔、平均树高呈正相关;对侧柏林而言,灌木可燃物负荷量与平均树高呈正相关,草本可燃物负荷量与平均胸径、平均树高呈正相关,10h时滞枯枝负荷量与郁闭度呈正相关。

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
