In order to explore the feasibility of Populus deltoides as a biomass energy forest and to further select more promising clonal varieties suitable for biomass energy forest,a study was conducted with eight clonal P.deltoides as subjects.A ran-domized block design was implemented to establish biomass energy forests,and 17 indicators,including diameter at breast height and plant height,were measured.Data analysis was performed using principal component analysis and multiple line-ar regression analysis.The results showed that all eight clones are important species for biomass energy forests,with clone 2 being the most optimal,followed by clones 4 and 3.Using a stepwise regression approach,a regression equation was de-veloped for individual biomass(W)in relation to diameter at breast height(D)and plant height(H),resulting in W=2.878 7D+0.655 3H-16.528 0.By measuring the diameter at breast height and plant height,biomass can be quickly esti-mated,providing important references for the management of P.deltoides biomass energy forests.
