Study On Characteristics Of Carbon Monoxide Distribution In Great Xing'an Mountain

This study analyzed analyzed the Great Xing`an Mountain Forest region CO distribute characteristic in atmosphere with troposphere pollution remote sensor(MOPITT) and XP-100 carbon monoxide measure apparatus. and analysis of characteristics and influencing factors of CO content in the thickness of permafrost of the cool temperate zone, content of CO in the atmospheric and soil changes in the forest fire, it reveals basic Characteristics in the affects of permafrost , and relation between forest fire and flammability gas .which refers strong evidence for forest fire. Change of forest ecosystem climate and the permafrost protection.The results show that:1.The CO content in the atmospheric is high in April and may, mixing ratio of concentration of the CO is higher negatively correlated with the elevation every month , the column content of the CO increases year after year.2. The near surface CO is no changes before forest fire; the CO in the center of the near surface is zero during forest fire; the CO obviously increase in anaphase forest fire. The main affecting factors of the CO characteristics horizontal distribution are independent of forest fire incomplete combustion release of the Great Xing`an Mountain Forest.3. Forest fire reduce the content of combustible gas, and change the CO distribution pattern in the soil.4.The CO content distribution pattern is high during snow melt period based in the may , and CO content has a tendency of increasing with the depth of soil layer, and very stable under 55cm soil depth .5. The content of the CO in the individual soil is otherness in the different cutting degrees, shows Successive Cutting Forest> cutting-blanks > Virgin Forest, the CO content on Influence of the Soil-Rock Ratio is obviously, shows complex linear functional relationship; And has little influence on the soil temperature and the soil water.
