Abstract
Studies on the weak decays of charmed baryons provide useful information for understanding the interplay of weak and strong interactions in the charm sector.
In 2014, the BESIII experiment accumulated a data set of 567 pb$^{-1}$ at the center-of-mass energy of $\sqrt{s}$=4.6 GeV, an energy point slightly above the $\Lambda^+_c \bar{\Lambda}^-_c$ mass. This is the world first threshold data of the $\Lambda^+_c$ baryon and provides systematical measurements on the production and decay properties of the $\Lambda^+_c$. So far BESIII has published 17 papers of about 30 reaction channels based on the data set taken at 4.6 GeV. In this proceeding, I summarize the BESIII results on the $\Lambda^+_c$ decays in the recent three years. In addition, some prospects on the future programme of charmed baryons are discussed.
