- Abstract:
- A continuous fluvial sedimentary profile, Songjiang Hydrological Station is located near Songjiang Town, Jilin province. The environmental and fluvial deposits change indexes are related to the grain size, pollen analysis, with the AMS14C dating. Compared with the definite historical climate records, the climatic environmental change since 1000 years in the research region was discussed. The results show that the climate fluctuated in three stages, that is, the climate was cool and wet during 799~686 a B. P., warm and dry during 686~428 a B. P., wet and cool during 428 a B. P. -present. However, it has the tendency of becoming warm and dry. The results reflect that the climate change in different stages according with the historical records. Sedimentary profile shows that Baihe river bed has undergone three time fluctuation. The water conservation should be undertaken to protect from the loss of river sand and gravel.
