摘　　要：The soil physic-chemical properties of natural mixed stand of conifer and broad-leaved trees in different cutting operation site after 10 years(high intensity,45.8%;over-high intensity 67.1%;clear cutting)were quantitatively analyzed.The results showed that the bulk density of soil and the damage rate of soil structure increased,while the saturated water retention of soil and the total porosity of soil decreased.The content of soil nutrient generally decreased.The soil aggregate,soil water content property and porosity,and soil nutrient were not recovered after 10 years.With the felling intensity increasing,the destruction has deteriorated.The soil physic-chemical properties of natural mixed stand of conifer and broad-leaved trees in different cutting operation site after 10 years(high intensity,45.8%;over-high intensity 67.1%;clear cutting)were quantitatively analyzed.The results showed that the bulk density of soil and the damage rate of soil structure increased,while the saturated water retention of soil and the total porosity of soil decreased.The content of soil nutrient generally decreased.The soil aggregate,soil water content property ...
