Abstract

Update the location and scope as determined in the young stand Daxingan Mountains Xingan Larch and birch mixed forest over cutting and replanting measures more science, discusses the relationship between the regeneration pattern, location update and location in the tree. Cut-over forests of Larix gmelinii （larch）, Betula platyphylla（birch）, and Populus davidiana （poplar） were used with six aggregated indexes in test stands. Distribution of regeneration patterns was also aggregated. A correlation analysis of relative coordinates for diameter D10 cm was conducted. Results showed that the L. gmelinii forest with D10 cm was significantly correlated （correlation coefficent was －0.564－0.895, P =0.000－0.036） to regeneration location and pattern. The regeneration pattern was also affected by stand structure, the types of trees in the quadrats, and their mutual differences. Larch with D10 cm accelerated regeneration of Japanese white birch; whereas, Japanese white birch with D10 cm inhibited regeneration of larch. Regeneration layers, from top to bottom, had a vertical ladder distribution with B. platyphylla, then L. gmelinii, and then P. davidiana. The average forest height changed as follows: 13.7% to 75.0% （birch）, 12.8% to 72.8% （larch）, and 27.8% to 61.9% （poplar）. In the future, spatial patterns should be adjusted so the D10 cm parameter controls forest regeneration patterns, and for replanting so the D10 cm tree location and pattern choice, litter thickness, soil seed inaccessible locations as replanting position, and the position of potential natural regeneration avoid overlap thereby saving costs, promoting forest regeneration, and providing a more reasonable structure.［Ch, 1 fig. 6 tab. 15 ref.］
