摘要:
 以辽东山区不同林龄红松人工林为对象，设置30块不同立地条件样地，调查分析红松生长、林下灌草和土壤养分水分等特性，选取乔木层碳储量、土壤养分维持、土壤水源涵养、生物多样性维持、生产力和木材生产等生态功能，利用平均值法量化其多功能性，探讨不同功能间的协同-权衡关系和驱动多功能性的主要因子，以期为红松人工林的持续健康经营提供支撑。结果表明，辽东山区红松人工林多功能性指数在0.38~0.78，随林龄增加而显著上升。不同功能间以权衡关系占据主导地位；10龄红松人工林乔木层碳储量、生产力和木材生产三者之间权衡度为0、10、34龄和43龄土壤养分维持功能与其他功能间权衡度最高。红松活枝下高、优势木高、坡度、坡位、土壤C∶N、C∶K和N∶K是影响红松人工林多功能性指数的主要环境因子。为实现红松人工林的森林多功能性，在造林时立地条件尽量选择小坡度、阴坡和低坡位，营林过程中应避免高强度修枝，注重林下生物多样性保育，加强修枝剩余物和凋落物管理，必要时进行林地施肥，促进林分因子、地形因子和土壤养分间的协调发展，推动红松人工林持续健康经营。
Abstract:
 Taking Pinus koraiensis plantations with different ages in the mountainous area of eastern Liaoning Province as the research objects,30 plots with different site conditions were set up to investigate and analyze the characteristics of P.koraiensis growth,understory shrub and soil nutrients and water,and select the ecological functions of tree layer carbon storage,soil nutrient maintenance,soil water conservation,biodiversity maintenance,productivity and wood production.The average value method was used to quantify the multifunctionality,and the synergy-trade-off relationship between different functions and the main factors driving multi-functionality were discussed.The results showed that the multifunctional index of P.koraiensis plantation was 0.38-0.78,which increased significantly with plantation age.The trade-off relationship between different functions was dominant.Among them,the trade-off degree between tree layer carbon storage,productivity and wood production in the tree layer of 10-year-old P.koraiensis plantation was 0.And the trade-off between soil nutrient maintenance function and other functions was the highest in 10-,34- and 43-year-old P.koraiensis plantations.Under branch height,dominant tree height,slope,slope position,soil C∶N,C∶K and N∶K were the main environmental factors affecting the multifunctionality index of P.koraiensis plantation.In order to realize the forest multifunction of P.koraiensis plantation,the site conditions should be selected as small slope,shady slope and low slope position as far as possible during afforestation.In the process of forest management,high-intensity pruning should be avoided,understory biodiversity conservation should be paid attention to,pruning residues and litter management should be strengthened,and forest land fertilization should be carried out when necessary,so as to promote the coordinated development of stand factors,topographic factors and soil nutrients,and promote the sustainable and healthy management of P.koraiensis plantation.
