Abstract:

Bulk density of soil horizons for all 27 comparative study plots.

Design:

Soil profiles are located directly adjacent to the CSPs. Samples were taken horizonwise from soil profiles ( 3 samples each, averaged to 1). Samples exist according to the soil profile description per CSP (field 61 in the soil profile description sheets). If the specific soil horizon contained too many stones or roots no sample could be taken and the field has been left empty. Samples were dried in the laboratory at 105° C. After cooling the samples were weighted and the weight was divided by the volume of the sampling cylinder.

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 horizonwise from 1 soil profile per CSP

Temporal extent:

Samples were collected 2008 and 2009.

Data analysis:

Bulk density of the soil is the weight of the soil material for a defined volume, here 100 cubic centimeters.
