Phytolith analysis in the surface soils is not only an important approach of studying phytolith assemblages in the Quaternary sediments,but also a basis of Quaternary environment reconstruction.Phytolith from 41 sites of 6 areas and 3 climate belts of Northeast China were extracted and classified into 11 types: dumbbell-shaped-saddle-shaped,fan-shaped,square-shaped,rectangular-shaped,ladder-shaped,cap-shaped,point-shaped,crenate-shaped,elongate-shaped,and other-shapes.Analysis showed that,there were relations between the phytolith distribution and the latitude,the altitude,temperature and heat: with the increase of the latitude and altitude,the contents of dumbbellshaped,saddle-shaped,fan-shaped,square-shaped,rectangular-shaped and ladder-shaped phytolith decrease,or vice versa;a warmer temperature is always corresponding with higher contents of fan-shaped and dumbbell-shaped phytolith,the more humid,the higher content of fan-shaped phytolith.
