【摘要】 本文以辽东地区不同针阔比例、间伐强度和间伐方法的红松阔叶混交林为研究对象，通过5年的定期观测和对比分析，研究结果表明：间伐明显促进了保留木的生长，减少了林木枯损，提高了林分蓄积，降低了红松分杈，改善了林分的的土壤和植被状况，并能取得一定间伐收入。通过本项研究，制定出的一套适合该地区红松阔叶混交林较为直观、简便的抚育间伐技术，以指导林业生产。更多还原

【Abstract】 The Thinning effects and technologies were studied on the mixed forest of planted Pinus koraiensis and broadleaf trees in Liaodong region for 5 years. The results are as follows: the growth of residual trees significantly promoted, the death amount reduced, the stand volume increment increased, the forking rate of Pinus koraiensis decreased, the stand soil and vegetation ameliorated, and a certain thinning income acquired. A simple systemic thinning technology adequate for the mixed forest of planted Pinus koraiensis and broadleaf trees in Liaodong region were carried, conducting the forestry management and production.更多还原
