Mean values in all seasons and flats were 2.83 mg·m-2·d-1 for CH4 production, 2.27 mg·m-2·d-1 for CH4 oxidation, 35.27% for CH4 transportation ratio, 0.39 mmol·dm-3 for CH4 concentration and 6.18 mg·m-2 for CH4 pool.
The equalized electronegativity along with a large pool of topological indices are used for the purpose.
The results from enzyme-linked assay and dot blot experiment show that an enrichment pool has been obtained after four rounds selection, which can specifically recognize ricin.
lanceolata, soil microbial biomass and nutrient pool decreased significantly.
Less litter and slower decay rate in pure Chinese fir plantation were the crucial factors leading to the decrease of soil microbial biomass and nutrient pool in this area.
In order to accurately estimate the size of the carbon pool and the capacity of the carbon sink in the forested areas of Xiaolong Mountain in Gansu Province, we have established regression equations of organ biomass of eight tree species.
