Abstract:
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.
