Spatial problems in long-term forest planning

摘要: In modern forest planning, it is important to account for the value of timber production and other values forest. Important factors such as protection biodiversity, recreational use traditional uses forests are often connected specific places in forests, or spatial structure forests. Moreover, worth these difficult express objective terms because they usually valued based on individual preferences subjective evaluations complex situations. The this thesis analyze issues relating test approaches that can be used them more accurately planning processes. The studies appended approach from different perspectives. Paper I identifies some difficulties associated with consideration processes. II describes development testing a method eliciting preferences. Papers III IV concentrate design evaluation plans considerations. III, fragmentation indices were simulate changes distribution stand types within forested region over time. existing information requirements reindeer husbandry concerning management practices evaluate consequences adopting regimes husbandry. The results highlight importance being careful when Particularly dealing preferences, where represent objectives numerical terms, oversimplification misinterpretation result undesirable outcomes. case examined provide insights tradeoffs must made between objectives. presented herein should useful increasing efficiency process order ensure selected match decision maker's closely possible.
