The Lhasa detachment is of the PAP Tibet corps; think of the tibet corps like the tibet autonomous region's "Army National Guard".
Duties units of local PAP units are used to protect the nearby area of important structures, such as railroads(as seen here), prisons(they are not prison guards but are stationed nearby) along with dams. In fact, the 8th Duties Battalion, Lhasa Detachment's main role is protecting the qinghai-tibet railroad.
Think of the PAP like National guard + RCMP; Many PAP units have lineage tracing back to the PLA, and PAP troops go through the same basic recruitment process and standards as the PLA. They are active service members and are eligable for veterans benefits.
