摘　　要：A comparison of the geochemical features of loesses of New Zealand and China indicates that the distributions of the elements and their variations reflect the fluctuations of climate which can be compared with the oxygen isotope stages and glacial periods.New Zialand loess is different in source from Chinese loess.Therefore ,some differences are also noticed in their chemical compositions .Loess accumulation in New Zealand is later than that in China.Because of more rainfall in New Zealand and different distributions of loess the elements in loess have suffered stronger leaching than in China.A comparison of the geochemical features of loesses of New Zealand and China indicates that the distributions of the elements and their variations reflect the fluctuations of climate which can be compared with the oxygen isotope stages and glacial periods. New Zealand loess is different in source from Chinese loess. Therefore, some differences are also noticed in their chemical compositions. Loess accumulation in New Zealand is later than that in China. Because of more rainfall in New Zealand and different distributions of loess the elements in loess have suffered stronger leaching than in China.
