Effects of Tree Species Diversity on Fine Root Morphological Characteristics, Productivity and Turnover Rates

Fine roots (φ ≤ 2 mm) play an important role in the process of material and nutrient cycling forest ecosystems, but effect tree species diversity on functional characteristics fine is unclear. In this study, 1−7 subtropical communities with different richness were selected to study morphological characteristics, productivity (PRO), turnover rate (TUR) by continuous soil core extraction, ingrowth method, root analysis system. The effects PRO, TUR are also analyzed. results showed that increase community, including specific length (SRL) surface area (SSA) each community was not significant, PRO increased from 71.63 g·m−2·a−1 (Ligustrum lucidum pure forest) 232.95 (Cinnamomum camphora mixed seven communities), 0.539 times·a−1 0.747 times·a−1. Correlation redundancy richness, traits, physicochemical properties driving factors affecting characteristics. did change roots.
