The objective of the study was to introduce a simultaneous approach to extracting growth trends from diameter increment series by combining tree- and stand-level information in the framework of mixed-effects modeling. The model results are compared with those of the sequential modeling approach according to Yue et al. Can J For Res 41:1577–1589, (2011).(More)

The analysis of soil thickness and slope gradient in natural secondary forest of the Wudaohe forest farm showed that the area of the secondary forest whose soil thickness was lower than 30 cm and slope gradient was higher than 25 degrees was 2390.1 hm2, covering 83.5% of its total area, while the area with soil thickness of higher than or equal to 30 cm and(More)
