Boundary form effects of timberline ecotone on colonization of woody plants and timberline dynamics in Changbai Mountain
长白山林线交错带形状与木本植物向苔原侵展和林线动态的关系

With transect sampling,effects of forest boundary forms on specie composition and its distribution and on growth and death of colonizing woody plants were measured at the birch forest tundra ecotone in Changbai Mountain,Northeastern China.The boundary microclimate relative to forest boundary forms,causes of colonizing patterns,and timberline dynamics were also studied. Betula ermanii and Alnus mandshurica predominated in the colonizing woody species on forest boundaries.In general,transects facing c...
