AB -The recent vegetation of Nan Jen Shan has been studied by pollen analysis of surface deposits. Through comparison of present vegetation with pollen spectra, the recent vegetation of Nan Jen Shan was composed chiefly of Fagaceae, Lauraceae, Myrtaceae, Illiciaceae, Daphniphyllaceae, Magnoliaceae, and Theaceae, almost identical to the present ones. The pollen spectra did not reflect the present dominant species well. Generally speaking, they were under-represented, except most taxa of Fagaceae and Magnoliaceae showed over-represented. The vegetation formula can be expressed with the correction factor method (R-value) as:

V=Ca+Cy/2.13+Sy/0.41+Ill/0.04+Da/0.11+Pa/0.23+Li/15.44+Sch/0.81+Ma/2.27+Xpe(0.18Ca)+XSc(0.15Ca).

Aglaomorpha and Davallia, the epiphytic ferns, were almost disappeared in the present vegetation, but abundantly appeared in the spore spectra, thus a close canopy of recent vegetation could be inferred. Dicranopteris and Diplazium, especially D. donianum, the heliophytic and sciophytic ferns, their percentage in the spore spectra could be used as an indicator of open vs. close, or dry vs. humid vegetation of this area.
