Carbon stocks in Danish forest types

摘要: As part of international agreements, countries are now obliged to monitor their greenhouse gas emissions as well report possible sources and sinks. Carbon dioxide is one the six greenhouse gases listed in Kyoto Protocol, contributing global warming. Research conducted to gain knowledge on how maximise forest carbon storage capacity, albeit, there some constraints and limitations both role forests CO2 mitigation efforts estimation and comparison stocks. Forests provide multiple services which might be conflict a management strategy solely addressing storage. The comparison forest carbon stocks insofar limited for instance studies use different definitions dead wood and different soil depth. With respect a changing climate, subjected changes that not fully predictable yet. In this study, I have examined effect stand age, category, tree species, crown cover, broadleaf fraction, species biodiversity, precipitation previous land biomass, dead wood, floor stock Danish forests. main influence derives from stand age, cover. Depending pool two these variables explain more than 50% variation respective model. In general, older forests contain C younger ones. increasing biomass volume grows forest floor develops, thus, accumulates C. Each category characterized by its properties, which among others determine turnover rate SOM, consequently influencing stock. The significantly due litter quality root system. On average, high cover indicates bigger volumes hence, greater stock. Previous influences only stock. relative similar to absolute ones; here differs most, were e.g. broadleaf fraction and biodiversity enters Furthermore, other factors such management the market products former especially affects wood, market turn, gives an explanation for average age species. total, organic soil category contain most amounts 184 tC ha-1, stock contains 81.2 ha-1 about 1.16 stored 15.3 forest floor.
