Using soil moisture monitor(ThetaProbeML2x) and soil ring sampler methods

we analyzed the soil moisture and water capacity of the main landscape(forest

grassland)soil with a 300 cm depth in the water conservation forest region in the Hani terraces landscape in Yuanyang County

Yunnan Province. The results indicated that:(1) The distribution features of the three soil profile sample plot Ⅰ(forest)

sample plot Ⅱ(forest)

sample plot Ⅲ(grass) were "double-peak fluctuation" type with turning points at nearby the 60

140 and 230 cm.(2) The coefficient of variation of sandy soil moisture was higher than clay soil(sample plot Ⅰ

Ⅲ)

and the coefficient of variation of forest was higher than grass while both soil samples were clay.(3) The water storage capacity of both sample plot Ⅰ(forest) and on of sample plot Ⅲ(grass) were higher than sample plot Ⅱ(forest)

and values were similar

the water storage ability of clay loam was better than that of silty sand soil.(4) Both the max water holding capacity and capillary moisture capacity at the 0-160 cm depth were ordered as: sample plot Ⅰ(forest) higher than sample plot Ⅲ(grass) and higher than sample plot Ⅱ(forest)

this indicated the water retention function of sample plot Ⅰ(forest) and sample plot Ⅲ(grass) were higher

however

soil water regulation function of sample plotⅡ(forest) was higher.
