Báo cáo lâm nghiệp:"A height-diameter model for Pinus radiata D Don in Galicia (Northwest Spain)" docx

... whole-stand growth model for radiata pine (Pinus radiata D. Don) stands in north-western Spain is presented. In this model, the initial stand conditions at any point in time are defined by three state ... [48,51,98]. In addition, model errors in inventory data may be magnified by individual-tree models but remain less al- tered by simpler models such as whole-stand mode...
