| Abstract: | The effectiveness of water and soil conservation by intensive managements in the forest converted from farmland was done in Liping county and Majiang County, Guizhou province. The results showed that the vegetation interception, soil water holding capacity and the total water holding capacity of the various stand types were increased with biomass and soil thickness. Water holding capacity of above ground was lower than that underground in mature stands. The effectiveness of soil conservation in all stand types were obviously better than the control, and the average soil erosion modulus was 57.1% less than that of control. |
