| Abstract: | The principles and methodology of total station used in lofting survey and measurement of tree height and diameter at breast height were introduced,and the precision of measurement was analyzed according to law of propagated error.It was shown that total station used in large-scale plot sampling in forest ecosystem was feasible.The precision of grid vertex,the measurement of tree height and diameter at breast height about 300 meter from the control point was 1/100,1/250 and 1/50,respectively,which satisfied the demand of the specification for forest investigation and will provide referential values for the future large-scale plot setting and tree sampling in forest ecosystem. |
