Carbon dioxide fluxes in a farmland ecosystem of the southern Chinese Loess Plateau measured using a chamber-based method.

ABSTRACT:

Background

Farmland accounts for a relatively large fraction of the world's vegetation cover, and the quantification of carbon fluxes over farmland is critical for understanding regional carbon budgets. The carbon cycle of farmland ecosystems has become a focus of global research in the field of carbon dynamics and cycling. The objectives of this study are to monitor the temporal variation in the net ecosystem exchange (NEE) and soil respiration in a spring maize (Zea mays L.) farmland ecosystem of the southern Loess Plateau of China.

Methods

A fully automated temperature-controlled flux chamber system was adopted in this study. The system contained nine chambers for CO₂ flux measurements, and three treatments were conducted: with and without maize plants i
