Estimation of Surface Fuel Loadings of Chinese Fir Plantation and Masson Pine Plantation in Zhangping City Based on Rs

Chinese fir plantation and Masson pine plantation are two fire-prone fuel types distributed in Zhangping city,their fuel loadings determine fire behavior.Based on the calculation of mean vegetation fraction of each Chinese fir plantation stand,mean canopy closures are also estimated by regressive analysis.After careful comparison with the result of field survey,the original canopy closures of some fir stands,which had changed a lot,were corrected with the aid of remote sensing.Then,canopy closure,and other factors such as age,DBH,mean stand height were used to estimate the surface fuel loadings of Chinese fir plantation stands by the existing estimation equation,and each stand's combustibility,fire intensity and fire risk ranking were evaluated according to the result.Finally,the other fuel types of Masson pine plantation's surface fuel loadings were also estimated and analyzed.
