Soil warming increases soil temperature sensitivity in subtropical Forests of SW China.

ABSTRACT:

Background

Soil respiration (R _S ) plays an important role in the concentration of atmospheric CO₂ and thus in global climate patterns. Due to the feedback between R _S and climate, it is important to investigate R _S responses to climate warming.

Methods

A soil warming experiment was conducted to explore R _S responses and temperature sensitivity (Q ₁₀) to climate warming in subtropical forests in Southwestern China, and infrared radiators were used to simulate climate warming.

Results

Warming treatment increased the soil temperature and R _S value by 1.4 °C and 7.3%, respectively, and decreased the soil water level by
