research on characteristics of soil water-holding and infiltration were carried out.

③Characteristics of soil capillary,non-capillary porosity water-holding capacity,soil total absorption precipitation and effective precipitation show this order: Robinia pseudoacacia > Populus euramericana > Fraxinus chinensis > bare land,and soil water-holding capacity in 0-20 cm is better than that of 20-40 cm.

Through the multipoint location determination on soil water storage of different vegetation types in the middle and lower reaches of Nenjiang River Valley,the results show that the soil water storage of Pinus sylvestris var.

Based on the observational material from the experimental plots, we describe the roles of dynamic changes in rainfall, evapotranspiration, surface runoff, subdrainage and soil water storage on soil water cycle in latosolic red soil.

Soil water storage decreased 12.

tereticornis and Acacia mangium plantations on the soil physical properties and soil carbon storage in Hainan Island, China is studied in the paper.
