Influence of tree size, local forest structure, topography, and soil resource availability on plantation growth in Qinghai Province, China

Although diversity-ecosystem functioning relationships have been extensively studied, the impact of forest structure on productivity and the main drivers of this relationship remain unresolved. In addition to forest structure, local abiotic conditions affect tree growth, by influencing the diversity...
