In this paper,SPC-connectivity in L-topological space was studied.Firstly,the concept of SPC-connectivity was introduced by strong semi-open sets and strong semi-closed sets,and the equivalent characterization of SPC-connectivity was studied;Secondly,some properties of SPC-connectivity were discussed,and it was proved that SPC-connectivity was topologi-cal invariance;Finally,the relationship between SPC-connectivity and connectedness was discussed and it was concluded that SPC-connectivity must be connected in L-topological space,and it was not true the other way,thus further enriching and per-fecting the connectivity theory in L-topological space.
