Climatological Significance of Pollen Factors Revealed by Pollen-Climate Response Surface Functions in Dajiuhu,Shennongjia

Quantitative reconstructions of the mean July temperature and annual precipitation are performed based on pollen percentage contents from surface and stratum pollen samples,together with vertical meteorological observations across 700-2800 m in Dajiuhu,Shennongjia in Hubei Province of China.Canonical correspondence analysis and robust locally weighted regression of surface pollen samples are employed to investigate the relationship between plants and climate,and to build the seven pollen-climate response su...
