Effects of Topography on Radial Growth of Tree Species with Different Mycorrhizal Types

In the dynamic monitoring fixed sample plot of 25 ha coniferous broad-leaved mixed forest in temperate zone Northeast China, we used data from two surveys (2013 and 2018) microtopography plot, mycorrhizal type tree species to explore whether different types single terrain factors will affect radial growth with on a regional scale. We studied adaptability north end Changbai Mountain south slope Laoyeling mountain, which provided basis for further revealing response mechanism this area. found that: have higher rates gentle slopes than steep slopes. Tree sunny survival same shady The quantity AM (Arbuscular mycorrhiza) type, EcM (Ectomycorrhiza) ErM (Ericoid were significantly positively correlated types. slope. species, negatively aspect. position. believe that reasons these conclusions may be caused by differences soil temperature, humidity, water distribution
