Abstract:
Forest conversion is an important way of land use change, which changes soil ecosystem by changing forest vegetation type. Soil microorganism is an important component of soil ecosystem, and its change is closely related to the improvement of soil fertility. In this paper, phospholipid fatty acid method was used to study the soil microcommunity structure, soil nutrient and the relationship between the evergreen broad-leaved natural secondary forest and Chinese fir plantation in wufang forest farm in shunchang county, nanping city. The results showed that the total carbon content, total phosphorus content, ammonium nitrogen, microbial biomass carbon and C/N ratio of evergreen broad-leaved natural secondary forest were significantly higher than those of Chinese fir plantation (P<0.05), but there was no significant difference in total nitrogen content and available phosphorus content between the two stands( P > 0.05). The gram positive bacteria, fungus, total phospholipid fatty acid (total PLFAs), Gram positive bacteria gram negative bacteria ratio (G+:G-) and bacterial fungus ratio (F:B) of evergreen broad-leaved natural secondary forest were significantly higher than that of Chinese fir plantation.. Pearson correlation analysis showed that bacteria, fungi and total phospholipid fatty acids were significantly correlated with total carbon, total phosphorus, ammonium nitrogen and microbial biomass carbon content, and total phospholipid fatty acids were significantly correlated with pH (P>0.05). Principal component analysis showed that the first principal component and the second principal component together explained 97.86% of the changes in microbial community structure, indicating that there were significant differences in soil microbial community structure among different forest stands after forest conversion. Redundancy analysis showed that the first axis and the second axis explained 89.9% and 6.7% respectively. Soil total phosphorus, ammonium nitrogen and nitrate nitrogen had the greatest impact on soil microbial community structure. The results showed that there was a significant correlation between soil microbial community structure and soil nutrient content under forest conversion, which was of important reference value for improving soil fertility and building sustainable Chinese fir plantation.? ? ?
