Abstract

This study estimated the carbon fixation by 2 successional stages of biological soil crusts (BSCs) based on 4 years of field observations in the Shapotou region, located in the south-eastern fringe of the Tengger Desert, in Inner-Mongolia. Carbon fixation by 2 BSCs has been compared via estimating daily carbon fixation using measuring net photosynthesis with 10 sampling plots per crust stage in situ, combining with calculating the wet daytime of crustal cryptogam thallus. However, diurnal carbon fixation of both BSCs was largely determined by crustal water content rather than photosynthesis photon flux and temperature. These findings indicate the recovery of BSCs is expected to significantly increase carbon input into sandy desert ecosystems
