摘要

这项研究的目的是提出两个北欧国家混交林定义的统一标准,描述其主要混合类型,并概述其目前的范围。我们使用了芬兰和瑞典编制的国家森林清查数据,考虑了可用于木材供应的森林(FAWS),不包括冠层关闭前的幼苗和幼树样地。混交林的定义是基于阈值标准,该阈值标准表示一个林分中优势树种的基底面积占总面积的比例。随着阈值标准的提高,混交林的比例增加:芬兰从21%增加到42%,瑞典从24%增加到49%,阈值标准从65%增加到85%。在75%的阈值标准下,芬兰的混合FAWS面积为560万公顷(占FAWS的31%),瑞典为650万公顷(36%)。芬兰的优势混合类型为松-云杉-桦木混合(31%),瑞典的优势混合类型为松-云杉混合(29%)。各国泥炭地混交林的比例相似,均为9-10%。混交林比例由北针叶林向半针叶林增加,随着发育等级的增加而增加。

Current state of mixed forests available for wood supply in Finland and Sweden
This study’s objectives were to suggest harmonised criteria for the definition of mixed forests for two Nordic countries, describe their principal mixture types, and provide an overview of their current extent. We used national forest inventory data compiled in Finland and Sweden, considering the forest available for wood supply (FAWS), excluding seedling and sapling plots before canopy closure. The definition of the mixed forest was based on the threshold criteria, which indicate the basal area proportion of the dominant tree species of the total in a stand. The proportion of mixed forests increased with higher threshold criteria: 21% to 42% in Finland and 24% to 49% in Sweden, as the threshold criterion was changed from 65% to 85%. With a threshold criterion of 75%, the area of mixed FAWS was 5.6 million ha (31% of FAWS) in Finland and 6.5 million ha (36%) in Sweden. The dominant mixture type was the pine-spruce-birches mixture (31%) in Finland and the pine-spruce mixture (29%) in Sweden. The proportion of peatland forest of mixed forests was similar in the countries: 9–10%. The mixed forests proportion increased from north boreal to hemiboreal, increasing with more mature development classes.
