Land cover change and soil organic carbon stocks in the Republic of Ireland 1851–2000

摘要: Using both historic records and CORINE land cover maps, we assessed the impact of change on stock soil organic carbon (SOC) in Republic Ireland from 1851 to 2000. We identified ten principal classes: arable land, forest, grassland, heterogeneous agricultural areas/other, nonvegetated semi-natural areas, peatland, suburban, urban, water bodies, wetland. For each class, SOC was estimated as product density area. These were summed calculate a national budget for Ireland. The Ireland’s 6.94 million hectares have undergone considerable over past 150 years. most striking feature is decrease 1.44 ha 0.55 Over same time period, forested increased by 0.53 ha. As 2000, lands including (7.85%), grassland (54.33%), areas/other class (7.91%) account 70.09% Irish cover. estimate that Ireland, 1 m depth, has 1,391 Tg 1,469 2000 despite loss due urbanization. This increase largely with its higher stocks when compared lands. Peatlands contain disproportionate quantity stock. Although peatlands only occupy 17.36% area, they represented 36% (to depth).
