摘 要:定量分析轻度择伐对人工林林地土壤理化性质的短期影响,结果表明:轻度择伐后林地土壤理化性质受到一定程度的影响,但并不明显.土壤结构体破坏率、土壤容重略有增加,最大持水量和总孔隙度略减小;土壤养分含量普遍略有下降.从森林生态采运角度出发,提出减轻择伐作业对林地土壤破坏的具体措施.The short period effect of selective cutting ( low intensity) on the physical and chemical properties of soil in plantation forest in rotation was analyzed quantitatively. The results showed that the damage rate of soil structure and the bulk density of soil slightly increased, the saturated water retention of soil and the total porosity of soil slightly decreased. The content of soil nutrient slightly decreased generally after selective cutting. Based on that, some measures of reducing the damage of ecological environment of forest caused by selective cutting were put forward for the ecological harvesting operation.
