Dataset Abstract

Coarse roots play important role in the storage of carbon in forest ecosystem. The coarse root density is a key index to explain the relationships between coarse roots spatial distribution and biotic and/or abiotic factors. By TreeRadar, we scanned the subplots (10m*10m) in each CSP to know the coarse root spatial distribution without destroying the environment.

Dataset Design

In each csp, there are nine sub-plots, we scanned three of them by radar with 10 lines. The length of each line is 10m and 1m interval between two lines. All csps (25 plots) have been studied.

CSP
Reasearch plots of the Biodiversity - Ecosystem functioning experiment (BEF-China). There are three main sites for research plots in the BEF Experiment: Comparative Study Plots (CSP) in the Gutianshan Nature Reserve, having a size of 30x30m^2, measured on the ground.
