Gray Correlation Analysis of Fuel Load and Stand Factors

With the 32 pieces of sample data for larch in Daxing´anling region, the gray correlative degree and correlative sequence between stand factors, such as tree age, crown cover, tree height, diameter at breast height(DBH) and so on, and forest surface fuel load were figured out by gray correlative analysis; The main factors affecting forest surface fuel load were determined and the quantitative analysis results for the relation between stand factors and forest surface fuel load were achieved. The research established for the selection of the main factors of forest surface fuel load model provides a more quantitative evaluation of the scientific method, making estimation of forest stand factors according to the main surface fuel load model more reasonable and practical.
