  3. 2. Optimal thinning : a theoretical investigation on individual-tree level

    Författare :Peter Fransson; Åke Brännström; Ola Lindroos; Oskar Franklin; Per Lundberg; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forest management; Simulation; Optimization; Spatially explicit model; Individual-based model;

    Sammanfattning : Paper I: In paper I, we asked how a tree should optimally allocate its resources to maximize its fitness. We let a subject tree grow in an environment shaded by nearby competing trees. The competitors were assumed to have reached maturity and had stopped growing, thus creating a static light environment for the subject tree to grow in. LÄS MER

  4. 3. Trade-off analysis of forest ecosystem services – A modelling approach

    Författare :Xi Pang; Ulla Mörtberg; Berit Balfors; Brian Fath; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Forest bioenergy feedstock; Landscape simulation; Forest simulation; Ecosystem services modelling; Integrated sustainability assessment; Spatial optimization; Optimization heuristics; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : Forest is a resource that is increasingly utilized for multiple purposes. The balance between energy demands and the long-term capacity of ecosystems to support biodiversity and other ecosystem services is crucial. LÄS MER

  5. 4. A Systems View of Advancements in Biomass Supply Chains

    Författare :Johanna Enström; Aron Larsson; Leif Olsson; Lars Eliasson; Anders Eriksson; Daniel Nilsson; Mittuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forestry logistics; Supply Chain Management; Discrete Event Simulation; Forest fuel;

    Sammanfattning : Forest fuel is an important source of energy with potential for increased use in the Nordic countries. Profitable forest operations are dependent on logistics as the forest is a natural resource with varying conditions over widespread areas. LÄS MER

  7. 5. Individual-tree-selection in uneven-sized Norway spruce stands in southern Sweden : Developments of tools for simulation and optimization

    Författare :Nils Fagerberg; Johan Bergh; Peter Lohmander; Stergios Adamopoulos; Hubert Hasenauer; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; continuous cover forestry; selective cutting; Picea abies; uneven-aged; single-tree-selection; growth model; knot size model; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Individual-tree-selection (ITS) is a continuous cover forestry method that aims to utilize the uneven-sized stand structure through optimized individual tree selections. ITS is an interesting management alternative to rotation forestry in terms of production of multiple benefits and forest owner profitability. LÄS MER
