The objective of this research was to examine the effects of
different landuses within the A-Li San forest land, Taiwan. The
experiments were carried outby both bench and field soil
tests to investigate the water conservationcapacity in the
test sites.
1.The final infiltration rates for the different areasare
compared as flow: (a)Forest District #7: forest > marstard
garden (b)Forest District #146:
bamboo > tea > alameda (c)Forest
District #151: forest > bamboo > betel nut > tea
The results also demonstrated that the rate of the upper-
layer-soil at District #146 was higher than the lower-layer-
soil''s. 2.The regression equations for
estimating final infiltration rates with influencing
factors are listed below:
forest : Ft= -27.5555 + 1.3446Pc
bamboo : Ft= -60.4407 + 2.3522Pc + 0.6494O.M
marstard : Ft= 11.6564 + 0.0430Pc - 0.3785Clay
betel nut : Ft= -26.1088 + 1.2463Pc
tea : Ft= -27.6102 + 1.2931Pc
In these equations, Ft is the final infiltration rate of soil(
mm/min), Pc isthe macroporse content(%), O.M is the organic
matter content(%),and Clayis the clay content of soil
texture(% ).
