The Lopingian is one of the fastest rising periods of seawater strontium isotopic ratios (^87Sr/^86Sr) in earth history, and its mechanisms and increasing rates of the ^87Sr/^86Sr evolution were still disputed widely. These disputations among researchers were caused mainly by timeframe selection (sections' thickness or data of radiometric ages), and different stratigraphic boundaries and un-upmost dated ages. This paper examined published ^87Sr/^86Sr data of the Lopingian, and projected them on timescales based on evolutionary and age constrained conodonts fossils. ^87Sr/^86Sr evolution vs fossil constraining timescales was re-established in this period. This research suggests: (1) ^87Sr/^86Sr excursion projects on fossil zones can truly support ^87Sr/^86Sr evolutionary pattern in the period; (2) ^87Sr/^86Sr evolution provides a new approach for stratigraphic research of marine carbonate sections in lieu of biostratigraphic data; (3) ^87Sr/^86Sr stratigraphy works on marine carbonate sections of different sedimentation rates even between different basins; (4) the ^875r/^86Sr data and its shift was dependent on samples materials and chemical treatment methods; (5) the increasing rate of marine water ^875r/^86Sr in the Late Permian is suggested as 5.4× 10^-5/Ma or slightly lower; (6) sedimentation age and its ^875r/^86Sr of the Lopingian marine carbonate suggested as: Dpro=259-(Rs- 0.70695)/5.4×10^-5 (Ma).
