| 摘 要： | 主伐方式基本上可分为皆伐、渐伐和择伐3大类.从生态角度看,择伐对森林生态环境影响最小,并使森林的3种效益达到最完美的结合,而皆伐对生态的破坏最大1].

| Abstract: | The soil physic-chemical p roperties of natural mixed stand of conifer and broad-leaved trees in differentcutting 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, soilwater content p roperty and porosity, and soil nutrientwere not recovered after 10 years. With the felling intensity increasing, the destruction has deteriorated. |
