Spatial-temporal patterns of net primary production in Anji (China) between 1984 and 2014

Abstract Long-term and persistent human disturbances, such as the changes in land use types, have degraded the carbon fixation capacity of forest ecosystems. In Anji, China, the changes in land use types, such as the urbanization and increase of Moso bamboo forest, had changed the distribution of the broadleaf forest, needle leaf forest, and Moso bamboo forest, which in turn affected the net primary production (NPP) at the regional scale. This paper used the Carnegie-Ames-Stanford approach (CASA) model to estimate NPP in Anji during the period 1984–2014. The referenced NPP measured by eddy covariance technique was used to validate the simulated NPP, and the results show that the simulated NPP was consistent with the referenced NPP (R2 = 0.90, p
