moist climate
4.The loess features appear mainly wind phase with the wind--water two phases by calculating grain size prameters and analysing the grain--size. The high content of clay(<5 μm), with the average of 54.32%, and mulistory calcareous loess layers indicate that it is formed in the condition of moist climate, dominating summer monsoon.
5.They have survived the destructive influences of man through their location in precipitous topography and the moist winter micro-climate.
6.By using various oxide ratios in argillite, the paper discussed the situation of Paleoclimate and its evolutioary law from Carboniferous to Jurassic Period in Shanganning Basin. From Mid - Carboniferous to mid - Triassicepoch and late Triassic epoch to Antinian, the ratios of various oxides in argillite show two unsimilar cycles which gradually increase or decrease in vertical profile,accordingly, during the same period the paleoclimate exists the early and late two cycles i. e. from the moist to semimoist and semiarid climate.
7.during 3.75-3.47 Ma the vegetation belonged to mountainous,warm-temperate,mixed needleleaf and broadleaf forest and the climate changed from cool-dry to warm-moist;
