<正>引用“双维系统法”作为研究的基本出发点，通过建立立地质量评价模型、经营模型、胶合板材出材量模型及综合地确定合理的主伐年龄，对Ⅰ－６９杨胶合板用材林栽培模式进行了优化研究，提出了在不同立地条件下的优化栽培模式，并对优化栽培模式经济效益进行了分析，认为在Ⅰ－６９杨栽培区进行胶合板用材林的培育是非常适宜的，并为Ⅰ－６９杨胶合板用材林的模式化培育提供了科学的依据。

Based on the investigation data which came from came from pure plantations of Ⅰ-69 [Populus deltoides bartr.cv.“Lux”],site quality evaluation models,cultivation models and plywood volume modelswere fitted with ordinary the least square technique.The cutting ages were determined comprehensively. In order to select the optimum cultivation Patterns of Ⅰ-69 plantation for plywood in each site index, the rank method with relative weight coefficient was used and economic benefil for each cultivation pattern was also evaluated in the paper.As a result,a detail optimum cultivation pattern of Ⅰ-69 industrial plantation for plywood for each site was developed. Finally.we consider that it is very suitable to silviculture industrial plantation for pulpwed in Ⅰ-69 cultral area.
