摘要
斯洛伐克条件下的大规模扰动,特别是风暴和树皮甲虫引起的扰动,除了带来其他负面后果外,还带来了该国碳预算的急剧下降。斯洛伐克林业现代史上最大的动乱是2004年11月发生的风暴破坏。塔特拉国家公园(TNP)是受影响最严重的地区之一。因此,在这一地区,建立了两个样带(T1 - Danielov dom遗址和T2 - Horný Smokovec村附近),以调查灾后建立的幼林树木的基本树木特征。利用树干基部测量的树高和树径,结合区域特异异速生长关系,计算了2014年春、秋两季林分地上生物量蓄积量。在此基础上,估算了树木覆盖的地上净初级生产量(ANPP)及其组成部分(茎、枝、叶)。ANPP为315 g m−2 /年(样本T1), 391 g m−2 /年(样本T2)。在样带T1和样带T2之间,发现了ANPP结构的差异,即树成分的贡献。它们是由树种组成的对比引起的,特别是挪威云杉和阔叶树种之间的比例。阔叶树比云杉将更多的生物量分配给叶片。这种现象加上较高的叶片周转量(一年一次),导致阔叶比木质部分(茎和枝)的固碳量表现出更高的快速循环碳份额。在样带内,即样地(微点)之间,ANPP具有较高的变异性。对于TNP境内干扰后地区地上部分乔木蓄积量和ANPP的代表性估算,应在一个研究样地网络上进行调查。只有这种方法才能可靠地估计木本部分的固碳量,并最终估计幼林每年吸收的碳量。
Aboveground Net Primary Production of tree cover at the post-disturbance area in the Tatra National Park, Slovakia
Abstract Large-scale disturbances under the conditions of Slovakia, caused especially by storm and bark beetle, bring dramatic decline in carbon budget of the country, besides other negative consequences. The largest disturbance in modern history of the Slovak forestry was the storm damage that occurred in November 2004. The Tatra National Park (TNP) was one of the most affected regions. Thus, in this territory, two transects (T1 – the Danielov dom site and T2 – near the Horný Smokovec village) were established to survey basic dendrometric properties of trees in young stands established after the disaster. The standing stock of aboveground biomass in tree cover for the spring and autumn 2014 was calculated using the recorded variables, i.e. tree height and diameter measured at the stem base, together with the region-specific allometric relations. Then, the Aboveground Net Primary Production (ANPP) in tree cover was estimated with respect to its components (stem, branches and foliage). ANPP was 315 g m−2 per year (Transect T1), and 391 g m−2 per year (Transect T2). The differences in the structure of ANPP, i.e. contribution of tree components, were found between transects T1 and T2. They were caused by the contrasting tree species composition, specifically the ratios between Norway spruce and broadleaved species. Broadleaves allocated more biomass production to foliage than spruce. This phenomenon together with higher turnover (once a year) of foliage caused that broadleaves manifest higher share of fast-cycling carbon in comparison to the amount of carbon sequestrated in woody parts (stem and branches). High variability of ANPP was found within the transects, i.e. among the plots (microsites). As for the representative estimation of the standing stock of aboveground part of tree cover as well as ANPP at the post-disturbance area in the TNP territory, the survey should be performed on a net of research plots. Only this approach enables reliable estimates of carbon amount sequestrated in woody parts, eventually carbon yearly absorbed by young forest stands.
