Progress was made in the study of the spatial variation of soil enzyme activity.

Various extracellases in soil can catalyze the decomposition of soil organic matter and play an important role in regulating the nutrient cycle process of carbon, nitrogen and phosphorus in ecosystems.
by environmental heterogeneity and its sensitivity to the outside environment, soil enzyme activity still shows a high degree of spatial variation on a small spatial scale, but its influence factors are not yet known.
Researchers at Wuhan Botanical Garden of the Chinese Academy of Sciences analyzed the activity characteristics of soil enzymes within each ecosystem and explored the biological and non-biological factors of spatial variation at two different spatial scales (100m2 and 1m2).
results show that apoptosis and root biomass are the dominant factors that determine the active variation of soil enzymes in woodlands, while soil pH and microbial community composition are the dominant factors that determine the activity variation of soil enzymes in thickets.
and microscale (1m2), the dominant factors in the micro-environment of Tree patch and non-plant plaque (Inter-patch) were significantly different.
results are helpful to further reveal the response process and mechanism of microorganism and soil nutrient cycle to vegetation restoration.
the study was funded by the National Natural Science Foundation of China (31470557, 31770563) and the Chinese Academy of Sciences Strategic Pilot Special B (XDB15010200), the results of which were supported by How do biotic and abiotic factors regulation soil environment activities at the plot and microplot scales under the affor? Published in the international journal Ecosystems, Wuhan Botanical Garden is the first author unit, Li Qianxuan (now working at China University of Geology (Wuhan)) is the first author, and Cheng Xiaoli is the author of the newsletter.
