Objectives]Crown architecture is one of important determinants of productivity and yield of plantations since it comprises branches and leaves orientation and distribution,thereby affecting canopy density,light interception and carbon assimilation. Identifying and quantifying the underlying factors contributing to crown architecture are therefore important for a better understanding and optimization of stand productivity. However,the measurement of crown architecture of a tree is difficulty and consuming. [Method]To make the crown architecture measurement work easier,more precision and less consuming,a new method of obtaining architecture character parameters with 3 D laser scanner was studied. To analyze precision of the method,the diameter at breast height ( DBH ) and height of poplar 03-04-171 ((Populus deltoides cl.‘55/65’ × P. deltoides cl.‘2KEN8’) × (P. nigra‘Brummen’× P. nigra‘Piccarolo’) ) in a 6-year-old forest planted in a stand density of 2 m × 3 m were measured with direct ( harvest) and scanner method. The crown architecture parameters ( the primary branch length, branch angle, azimuth, branch curvature and ratio of branch bow to string of proletpic branch and sylleptic branch ) were measured to analyze the feasibility of the new method. Regression analysis was used to compare the method of direct measurement ( harvest) and indirect ( 3 D laser scanner) measurement of the crown architecture parameters. [Result]The results showed that the 3 D laser scanner had a high precision(DBH: R2 =0. 967 72,P=8. 26 × 10 -13; Height: R2 =0. 965 27,P=1. 440 29 × 10 -12 ) in measuring the crown architecture parameters and could be used in crown architecture measurements. The scanned results showed that the primer branch length,branch angle and branch azimuth had a similar rhyme in each growth unit ( the aboveground part that the temperate trees growth in one year) of the trunk,and the six-years-old tree had five growth unit. The branch was short in the bottom of the growth unit and longer in upper side of each growth unit. The branch angle in the lower and middle side of growth unit was larger than that in the upper side. The azimuth was larger in the middle part of growth unit,however smaller in lower and upper site of the growth unit. The proleptic branch distributed in upper side of each growth unit while the sylleptic branch distributed in middle and lower side. Proleptic branches accounted for 1/3 of the total number of crown branches. In conclusion,in each growth unit of stem,branches in the top of growth unit ( proleptic branch) were longer and upstanding,while the branches in the middle of growth unit ( sylleptic branch) were relatively short and had a large branch angle. The branches in the top of crown were short and erect,the branches in the middle crown had a larger angle in origin,and the lower branches had a lager azimuth. The ratio of bow and string branches was steady in all branches of the crown. [Condusion]The obtained results through 3D laser scanner were consistent with other measured results,suggesting that the 3 D laser scanner method could be used in measuring and analyzing crown structure.
