Abstract We extend the study of economically optimal carbon storage to a previously unexplored forest type, mixed-species size-structured stands. The ecological model applied in is transition matrix with growth functions for boreal Norway spruce ( Picea abies (L.) Karst.), birch Betula pendula Roth and B. pubescens Ehrh.), other broadleaves. broadleaved trees are assumed have no commercial valu...

Abstract The feature extraction of a point cloud fragment model is the basis splicing, which provides technical support for research on segmentation, and restoration surfaces. High-quality extraction, however, complicated process due to diversity surface information model. For this subject, high-efficient method was proposed address new extracting lines. First, projection distance calculated id...
