Site-specific critical loads of acid deposition on soils in the Edmonton 83H West map sheet, Alberta /
Notice bibliographique
Résumé
relatively low amounts of organic matter are the most Highly Sensitive to acid deposition.All other soils in the grid cell, being of finer texture and having A horizons rich in organic matter, were rated based on the basis of previous studies as being of Low Sensitivity.Acidification sensitivity categories of soils examined in this study were compared to sensitivity classes in mapping carried out by Holowaychuk and Fessenden (1987).In the Holowaychuk-Fessenden mapping, the Cooking Lake moraine (i.e., the Islet Upland Land System) was identified as having soils with potentially Moderate Sensitivity, and the Graminia Plain was categorized as being of High Sensitivity.All other soils were categorized as being of Low Sensitivity to acidification.The ARC modelling results suggest that the predominantly Luvisolic soils of the Islet Upland have Low Sensitivity to acidification.Other differences between the Holowaychuk-Fessenden mapping and the ARC model results pertain to the sandy Brunisolic soils of areas such as Redwater Plain, Eldorena Plain and Halfway Lake Dunefield, in the north part of the Edmonton West grid cell.These are mapped as being of Low Sensitivity in the Holowaychuk-Fessenden map.In the current study, some of the soils that characterize these Land Systems were indicated as being Sensitive or of Moderate Sensitivity according to the ARC model.A map depicting the Land Systems, land cover and soil sensitivity to acid inputs in the Edmonton West map sheet was developed based on the soil sensitivity assessment and on land cover information.Proportions of soil series within Land Systems were estimated from information provided in AGRASID, and from this, the proportions of soils in Moderate to Sensitive (Nestow and Primula), Moderate to Low (Helliwell and Mundare), and Low (all other soils) acidification sensitivity categories were derived.The assignment of Sensitive, Moderate and Low Sensitivity categories was applied only to lands classified as having grassland, tree or shrub cover, on the basis of land use mapping by the Prairie Farm Rehabilitation Administration in 1993-1995.Wetlands, including peatlands, were considered to be of Low Sensitivity.Cultivated soils were not rated, nor were lands categorized as 'Other Lands'.Two sensitivity map units were developed: Low Sensitivity and Low-Moderate-Sensitive Mix.Portions of three land systems in the Edmonton 83H West Half grid cell were characterized as having a component of Sensitive and Moderately Sensitive soils.These are the Eldorena Plain, Redwater Plain, and Halfway Lake Dunefield.Other Land Systems likely have small components of Sensitive and Moderately Sensitive soils, but of too low extent to enable mapping at the scale applied in this assessment.Sensitive soils account for 0.65% and Moderately Sensitive soils account for 2.3% of the entire grid cell area.As defined in the Acid Deposition Management Framework (Clean Air Strategic Alliance and Alberta Environment 1999), this finding does not support the assignment of this grid cell to a Sensitive or Moderate Sensitivity rating.1.0

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
