Relative pollen productivity (RPP) and relevant source area of pollen (RSAP) are the key to the reconstruction of past land cover quantitatively with Landscape Reconstruction Algorithm (LRA). Ta-pieh Mountains (30°10'~32°30'N,112°40'~117°10'E) is a transitional zone between subtropical evergreen broad-leaved forest and warm temperate deciduous broad-leaved forest, which is sensitive to climate change. The study of RPP and RSAP in this area will contribute to improving the modern process of pollen in subtropical zone. Using modern pollen assemblage and vegetation data at 56 sampling sites from the Ta-pieh Mountains, this paper estimated the RSAP and RPP of the 17 main pollen types in this area, and reconstructed the modern vegetation coverage of the tree pollen taxa. The estimated 17 pollen taxa including Pinus, Quercus,Liquidambar formosana, Castanea and Poaceae exceeded 90.14% of pollen in all sampling sites, and the corresponding average vegetation coverage also reached 90.87%, which approximately represented the sedimentary pollen and vegetation in this study area. Extended R-value(ERV) model analysis showed that the submodel 1 combined with the Prentice model had the highest goodness of fit with the vegetation-pollen data in the study area. Using the maximum likelihood function score, the RSAP was obtained at the distance of 340 m from each sampling point. The smaller RSAP in Ta-pieh Mountains compared with other areas may due to the difference of the vegetation spatial patterns and vegetation survey method. With Quercus as the reference taxon (RPP = 10), the highest RPP came to Pinus (6.202 0.107). And other tree plants were Pterocarya stenoptera(1.5550.080),Castanea (0.5300.026),Platycarya strobilacea (0.4340.040),Alnus trabeculosa (0.266 0.074), Liquidambar formosana (0.148 0.029), Anacardiaceae (0.141 0.018),Cunninghamia lanceolata(0.0230.004); RPP of shrubs and herbaceous taxa were Artemisia (0.3180.065),Aster tataricus type(0.1430.018), Hamamelidaceae(0.0560.022),Leguminosae(0.0230.008),Rosaceae (0.0200.009), Poaceae (0.019 0.001) and Moraceae (0.010 0.007) respectively and the ferns (0.266 0.021). Liquidambar formosana,Pterocarya stenoptera, Platycarya strobilacea,and Anacardiaceae were first estimated all over the world, their RPP were lower(except for Pterocarya stenoptera). The RPPs of one taxon varied sharply among regions may be related to the differences of species and human factors. The Landscape Reconstruction Algorithm analysis showed that the RPP results obtained in this study are reliable and could be applied to the reconstruction of ancient vegetation in subtropical-warm temperate zone deciduous broad-leaved forest.
