Abstract

How did the water conservation in the soil change when the natural evergreen broadleaf forests were regenerated to the plantations ?The aim was to provide a basis to protect the natural evergreen broadleaf forests and manage the plantations .This research studied water conservation in the soil of a natural evergreen broadleaf forest and three plantations , namely Sassafras tsumu , Cryptomeria fortunei , and Metasequoia glyptostroboides plantations , that were formed by artificial regeneration within the natural evergreen broadleaf forest in Muchuan County of Sichuan in July of 2004 and 2005 , by typical sample plots method , statistical analysis and correlation analysis . Results showed that compared with the natural evergreen broadleaf forest , soil organic matter in the three plantations significantly decreased (P 0.05) and bulk density significantly increased (P 0.05).For the C .fortunei plantation soil total porosity and capillary porosity , maximum and minimum water holding capacity , as well as the capillary porosity water holding capacity of the 20 -40 cm soil layer were significantly lower (P 0.05) than the natural evergreen broadleaf forest .S .tsumu and M .glyptostroboides plantations had fewer negative effects on original soil water conservation than the C .fortunei plantation .A close relationship (P 0.05) existed among soil organic matter , bulk density and porosity , water holding capacity , drainage capacity , and infiltration .Therefore , protecting and choosing appropriate tree species for artificial regeneration of a natural evergreen broadleaf forest are important for increasing water conservation in forest soils so as to decrease surface runoff losses .[ Ch , 4 tab .15 ref .]
