Surface pollen from various montane vegetations in Shalixian Mt. and Lepei Mt. of central and northern Taiwan have been explored and analyzed. The pollen data were used to simulate vegetation types by using the biomisation technique. Computing three matrixes of pollen taxa, plant functional types and combined biomes, vegetation types at each site have been finally defined through the fuzz selections of a tie-breaking rule. The results show that surface pollen data can simulate the subtropical Castanopsis and Cyclobalanopsis forests, alpine warm-temperate Quercus and Quercus-Pinus forests, and alpine temperate/cool-temperate conifers of Tsuga-Picea and Picea-Abies forests. Simulated elevations of the forests are similar to actual locations of the forests. This study can add vertical surface pollen data for extending investigation of various vegetation types in China, provide PFT schemes and vegetation types in low-latitude and montane areas, and be applied as modern analogues for fossil pollen in order to reconstruct Quaternary vegetations.
