In this paper the functions of water resources conservation were studied on three kinds of artificially recovering plantations of soil and water conservation, grass planting, arbor mixed with shrub, mixed arbors(called patternⅠ,Ⅱand Ⅲ for short respectively) and control(not improving), in seriously eroded areas of subtropical granite red soil. The results showed that: the order of the maximum gross water capacity of stands was pattern Ⅱ pattern Ⅲ patternⅠ, respectively higher than control by 24.97%, 17.57% and 9.58%; the water capacity of ground vegetation of stands was respectively 49.2, 27.2 and 15.8 times of control; the ability of water conservation of bush, herbaceous and bryophyte was lower; the quantity of holding water in the 40?cm soil layer of patternⅡ was the best, patternⅠwas the worst. The ratio of initial and stable infiltration of different patterns were higher than that of the control in surface soil, ability of the infiltration in soil was improved to some extent. Protecting and improving soil structure for enhancing soil conserving water ability and soil infiltration, should be the key in improving the functinons of water resources conservation of forests of soil and water conservation in severely eroded soil.
