Multi-year rainfall reduction treatments lead to carbon dynamics in Xishuangbanna tropical rainforest...

In the 8th to 9th year of water control, the increase in mortality of large trees led to a sharp drop in plant carbon pools; the litterfall input and heterotrophic output of the rain reduction treatment were both greater than those of the control, and the net carbon sink was also greater than that of the control, resulting in the top soil layer 1 Rice carbon and nitrogen nutrients increased, but this could not compensate for the loss of plant carbon pools and the reduction of seedlings.

This study's focus on seedlings and analysis of intra-annual timescales expands our understanding of the relationship between tropical rainforests and drought

The result was published in " Agricultural and Forest Meteorology" under the title " The cumulative drought exert disruptive effects on tropical rainforests in the northern edge of Asia - Based on decadal dendrometric measurements and eddy covariance method " .
