摘要
近年来退化柞蚕场栽植红松成为辽东山区一种被林农广泛接受的生态恢复模式;但是,目前对这种恢复模式的适用范围、具体技术和实施效果还不甚了解。通过对辽东山区典型退化柞蚕场营建的柞树-红松混交林林分生长规律、红松结实规律的调查分析,初步揭示了该区域退化柞蚕场营建柞树-红松混交林的生长情况,确定了退化柞蚕场生态恢复柞树-红松混交林的最适造林密度。研究结果可为辽东山区退化柞蚕场生态恢复提供科学参考。
In recent years,planting Pinus koraiensis in degraded tussah becomes one kind of ecological recovery mode in degraded tussah which were widely accepted by farmers in mountainous area in Eastern Liaoning Province.However,at present the scope of application of this recovery mode,the specific techniques and its effects are still poorly understood.The growth and fruition of mixed forest of Quercus mongolica-Pinus koraiensis planted in degraded tussah in mountainous area in Eastern Liaoning Province was investigated.It is initially revealed the growth of mixed forest of Quercus mongolica-Pinus koraiensis planted in degraded tussah in this region,and determined the optimum density for ecological restoration in the mixed forest of Quercus mongolica-Pinus koraiensis in degraded tussah.Result can be provided scientific references for ecological restoration in degradation tussah in mountainous area in Eastern Liaoning province.
