Effect of Coarse Woody Debris on Soil Microbial Functional Diversity Following a Huge Ice Storm in South China

Abstract:

Soil microbe’s response to coarse woody debris (CWD) was assessed in two contrasting stands. The volume, percent cover and weight of CWD in the damaged stand were significantly much higher than the undamaged stand. Redundancy Analysis showed that CWD and soil nutrient had a significant effect on soil microbial community (p < 0.005). Decay class of CWD had the greatest influence on soil microbial communities, and soil nutrient was next to it. With increasing decay class, CWD was favorable for soil microbial functional diversity. Alkali-hydrolyzable nitrogen, available phosphorus and available potassium showed a positive correlation with decay class and made a positive contribution on soil microbial functional diversity. Stands without ice storm impact temporarily had higher soil nutrient content than those suffered severe damage at the early stage after ice storm. Soil microbial functional diversity had no difference between both slopes. Findings reflected that there were other factors affecting the soil microbes in forest ecosystem except for the CWD decomposition and soil nutrient.
