Supplemental Information

The raw data

DOI: 10.7287/peerj.preprints.26916v1/supp-1

Table supplementary 1 Detailed information before density adjustment

35-year-old Larix principis-rupprechtii was the vegetation type of the sample plots above, all the density adjustment work had been done three years before sampling. The data was collected in July 2012, SOC, TN and pH was the average of 5 soil layers 0- 50 cm.

Table supplementary 2. Species list for the understory vegetation of different thinning treatments

Treatments as in Table 1. Results were collected in 2015 July. NP measns “no presence of”. Importance value = RF + RD + RC, Relative frequency (RF) = (frequency of the specie / the sum of all specie s frequency) *100%; Relative density (RD) = (the number of individual specie / the sum of all species number) *100%; Relative coverage (RC) = (the coverage of an individual specie / the coverage of all plants) *100%.
