| 摘 要： | 针对辽西地区水土保持林中油松纯林比例过大造成的松毛虫危害严重、水土保持性能和经济效益低下等问题,开展了树种结构调整研究。20多a的试验结果表明,油松纯林经调整后,松毛虫危害减轻,水土保持性能提高,植物多样性增加,经济效益显著提高,形成了"有虫不成灾"、稳定性强的林分。

| Abstract: | Based on the problems of occurrence of pine moth in soil and water conservation forest of Pinus tabulaeformis in west of Liaoning and the lower soil and water conservation benefits and economic benefits,the adjusting researches in species structure were done.More than 20-year experimental result showed,after adjusting of pure forests of Pinus tabulaeformis,the damage of pine moth was no more serious.The soil and water conservation benefits and the plant diversification have increased.Economic benefits have remarkably grown.The stands had pine caterpillars but not seriously. |

| Keywords: | soil and water conservation forest Pinus tabulaeformis pure stand species structure benefit |
