亚热带季风区不同林型可燃物理化性质及燃烧性研究
A Study on the Physical-chemical Properties and Flammability of Different Forest Types in Semi-tropical Monsoon Area
摘要
Abstract
It is very important to study and use the difference in physical-chemical properties and flamma-bility of different forest types in the Semi-tropical monsoon area. The physical-chemical properties and combustion time of different forest types in the Semi-tropical monsoon area were determined and analyzed, with the following result: (1) In different forest types, the coniferous forest the moisture content, ignition point, and crude ash content were the lowest in the coniferous forest; but the crude fiber content, crude fats content, and lignin content were the highest, so the flammability was the strongest. (2) In different species components, the ignition point of leaves was the lowest with the highest crude fat content; the crude ash content and crude fiber content were the highest in branches, so leaves were easier to start burning, while the flammability of branches was stronger. (3) In different forest types, the combustion time of leaves had a significant correlation with moisture content, and had a very significant correction with crude ash content and crude fiber content , the combustion time of brancheshad a significant correlation with moisture content, crude ash content andcrude fiber content. Correlative models could reveal the influencing mechanism of physical-chemical properties of different forest types to flammability.关键词
