Abstract:
Soil physical analyses of all 27 comparative study plots. Mass-% of 8 grain size classes of fine earth < 2 mm of six depth increments per CSP. Total depth is 50 cm. Grain sizes discriminate between sand, silt, and clay.
Design:
Depth increments were taken from systematic corings: 1 coring per subplot means 9 corings per CSP. Samples were bulked from the 9 corings to one sample per depth increment (0-5, 5-10, 10-20, 20-30, 30-40, 40-50 cm.), so that 6 samples exist per CSP.
Spatial extent:
The Gutianshan National Nature Reserve (NNR) is located in the western part of Zhejiang Province (29º8'18" – 29º17'29" N, 118º2'14" – 118º11'12" E, Fig. 1). The Gutianshan NNR has an area of approximately 81 km2. From 27 comparative study plots (CSPs) soil samples were taken in 6 depth increments per CSP
Temporal extent:
Samples were collected 2008 and 2009. Lab analyses were carried from 2009 to 2011
