Pollen analysis of five surface samples on Liangwang Mountain of Chenggong (N24°57',E102°37') provides information about the quantitative pollen-vegetation relationship for major plant taxa. Vegetation data with coverage are estimated from each sampling site within the range of 20m.
Acorrding to the difference of R-values, the pollen types could be divided into two groups: 1. R> 1 .over-represented, the type containing Pinus, Ainus, Coriaria, Artemisia and some ferns; 2 . R< 1 , under-represented, the type containing Keteleeria, Castanopsis+Lithocarpus, Cyclobalanopsis Quer-cus, Myrsine.
The pollen deposition of Pinus is dependent on the pollen production and on the wind velocitie and wind direction in the April-May flowering seasons. The west wind is mainly reason to affect distribution of Pinus pollen.
