Dead Surface Fuel Loading of Pinus tabulaeformis Forest in Henan West Funiu Mountains
摘要
Abstract
Based on the data of field investigation on 102 sampling plots,9 indices which represented surface fuel loading,terrain,and environment were selected to investigate the regularities of spatial and temporal variations of the loading capacity of the fine fuels on the surface of Pinus tabulae formis forest by linear correlation method. Most significant correlations were found between the surface fuel loading and age class, slope,and the canopy density. The loading capacity decreased with the increase of slope degree, and tended to decrease with the increase of age class and canopy density, except that the loadings slightly decreased first and then began to increase at the age class of IV. The maximum loading capacity appeared in 30-year forest. The models of the loadings of the up and bottom layers were established as M1 =793. 533 + 7. 774X1-17. 863X3 and M2 = 1082. 972 + 13. 514X1 +902. 509X2 -34. 197X3,respectively.关键词
