Three land cover types,Caragana jubata shrub,Kobresia huinilis grassland and mixture cropland of Brassica juncea and Avena sativa in the southern region of the Qinghai Lake,were seleted to investigate their soil physical-chemical properties and soil organic carbon and total nitrogen content.

Study on the hierarchical classification method of land cover in the water-wind erosion region ——Taking Hengshan as an example;

Tupu analysis on the land cover evolving patterns in the new-born wetland of the Yellow River Delta;

Effect of land cover on sediment yield in the middle Yellow River basin;

Due to the significant effect of forest cover to soil loss,the Chinese government mandated that forest cover would significantly increase in the loess Plateau.

In the paper, the distribution of ambient CO_2 concentration of two different land-covers, Deyeuxia angustifolia and Carex lasiocapa, in the Sanjiang Plain was studied.
