Shrub Diversity and Niche Characteristics in the Initial Stage of Reconstruction of Low-Efficiency <i>Cupressus funebris</i> Stands

The upper reaches of the Yangtze River are a very important ecological barrier in China, but the ecological benefits of large-scale <i>Cupressus funebris</i> Endl.plantations are low. This study investigated 12 plantations of different compositions and densities, including two densities...
