Other AbstractTo understand the differences in soil respiration and the factors influencing the different levels of recovery in earthquake-affected areas, we selected different field plots: destroyed and treated areas, and undestroyed areas; and areas with different climate: natural recovery areas in the dry-hot valley climate and the humid subtropical climate. Soil respiration, plant biomass, soil enzyme activity, and their seasonal variation and correlations were studied from September 2015 to September 2016. The results demonstrated that the seasonal variation characteristics of soil respiration rate and nine biological properties (underground biomass and total biomass, microbial biochar and biological nitrogen, catalase, alkaline phosphatase, urease, cellulase, and sucrase activity) in the two climatic areas are lower in winter and spring and higher in summer and autumn. Soil respiration rate, biomass, microbial biochar and biological nitrogen, urease and sucrase activity were measured in the areas in both climatic regions; alkaline phosphatase and cellulase in the humid subtropical climate, and catalase activity in the dryhot valley climate. The biological properties appeared in different quantities in the different field plots: undestroyed areas > destroyed and treated areas > natural recovery areas. The recovery rate of each indicator was between 11% and 114% in destroyed and treated natural recovery areas. The influencing factors of soil respiration in the two climatic regions are different. In the dry-hot valley climate areas, total biomass, underground biomass, and soil urease activity were crucial. In the subtropical humid climate areas, underground biomass and soil phosphatase activity were predominant. This study shows that there are differences in soil respiration rates in different recovery areas. Plant biomass, microbial biomass, and soil enzyme activity were the main factors affecting soil respiration.
