Abstract:

The UK Forestry Commission seeks to expand forestry and provide more non-market benefits. It must therefore identify areas where afforestation will bring a high amount of particular benefits at acceptable costs. This thesis aims to develop a systematic framework to identify the best locations for specific forestry benefits and demonstrate its use in the existing policy context. Literature shows that economic instruments are being adapted to capture some of the spatial variability of the costs and benefits of land use change, but that a systematic framework for assessing this variability for po

Precise planting geometries, intensive silviculture and genetic selection are used to achieve this homogeneity. However, a natural variability is still introduced by micro-‐site conditions and disturbances. A substantial source of variation is caused by edge effects of neighbouring stands or other land use forms. The

Abstract:

High-severity disturbances are the primary drivers of Engelmann spruce-subalpine fir ecosystems in the southern Rocky Mountain. Recently, an unprecedented, landscape-wide (at least 250 km2) spruce beetle outbreak killed virtually all the Engelmann spruce on the Markagunt Plateau in southwestern Utah, USA. Results from dendroecological analyses suggested the combination of antecedent disturbance history and drought-driven stand development was responsible for creating suitable host conditions prior to the recent outbreak.

Our goals for this dissertation were to test the efficacy of spatial analysis tools in a forestry setting and make recommendations for their use. Reliable spatial analysis tools will lead to more effective statistical testing and can lead to useful mapping of spatial patterns. The data for this p

The conversion of UK even-aged conifer plantations to continuous cover forestry (CCF), a form of forest management that maintains forest cover over time and avoids clear-cutting, requires more frequent and spatially explicit monitoring of forest structure than traditional systems. Key aims of CCF management are to increase the spatial heterogeneity of forest stands and to make increased use of natural regeneration, but judging success in meeting these objectives and allowing an adaptive approach to management requires information on spatial structure at a within-stand scale.

Abstract:

У роботі зазначається необхідність аналізу просторового розвитку лісового господарства в рамках регіональної економіки в контексті формування підходу ,що дає можливість вивчати особливості еколого-економічних систем, механізми інтегрування їх елементів до регіонального простору, встановлювати закономірності функціонування, формувати на цій основі оптимізаційні моделі територіальної організації та стратегічні пріоритети розвитку територіальних та галузевих систем.<br>В работе отмечается необходимость анализа пространственного развития лесного хозяйства в рамках региональной экономики в контек

Abstract:

Les images à très haute résolution spatiale (THR) telles que les images Pléiades (50 cm en Panchromatique, 2m en multispectral) rendent possible une description fine de la structure forestière (distribution et dimensions des arbres) à l'échelle du peuplement, en exploitant la relation entre la structure spatiale des arbres et la texture d'image quand la taille du pixel est inférieure à la dimension des arbres. Cette attente répond au besoin d'inventaire spatialisé de la ressource forestière à l'échelle du peuplement et de ses changements dus à la gestion forestière, à l'aménagement du territoi

Magistro darbe yra nagrinėjamos neparametrinio knn (k-nearest neighbor) metodo taikymo galimybės Lietuvos sąlygomis vertinant tradicinius miško taksacinius rodiklius bet kokiame šalies teritorijos taške. Darbo objektas – Dubravos miškų urėdijos Dubravos miškas. Darbo tikslas – įvertinti neparametrinio knn (k-nearest neighbor) metodo taikymo Lietuvos miškų inventorizacijose galimybes. Darbo rezultatai. Nustatyta, kad taksacinių rodiklių įvertinimo knn metodu tikslumas kyla didinant apskaitos vienetų, išmatuotų vietovėje, skaičių. Pagrindiniai knn metodo parametrai, kuriais gauti geriausi rezu

Abstract:

Die Nutzung von terrestrischen Ökosystemen zur Befriedigung der Grundbedürfnisse der Menschheit hat tiefgreifende Auswirkungen auf das Erdsystem und führte zur Ausprägung von anthropogen dominierten Landsystemen. Diese sind von hoher Komplexität, da sie aus einer Vielzahl von unterschiedlichsten Einflussfaktoren angetriebenen Landnutzungsveränderungen hervorgegangen sind. Aktuelle Forderungen nach einer nachhaltigen zukünftigen Landnutzung erfordern ein fundiertes und integratives Verständnis dieser Komplexität. Das Hauptziel dieser Arbeit ist es, ein besseres Verständnis der raum-zeitlichen M

Abstract:

У роботі зазначається, що сучасні орієнтири в напрямку постіндустріального сталого розвитку обумовлюють формування нової методології дослідження лісового комплексу, коли територія розглядається не тільки як фізичний (природно-географічний) базис лісогосподарювання, а перш за все як простір розгортання інформаційних, інноваційних та знанняємних процесів.<br>В работе отмечается, что современные ориентиры в направлении постиндустриального устойчивого развития обусловливают формирование новой методологии исследования лесного комплекса, когда территория рассматривается не только как физический (при

Abstract:

The accurate assessment of forest persistence under environmental change is dependent on the fundamental understanding of the genetic consequences of human intervention and its comparison to that of natural processes, as declines in genetic diversity and changes in its structuring can compromise the adaptive ability of a population. The European beech, Fagus sylvatica, has experienced prolonged human impact over its 14 million ha range with contemporary forests harbouring high ecological, economic, and cultural value. Historical traditional management practices, such as coppicing and pollardin

Abstract:

O presente trabalho teve como objetivo principal a aplicação de uma metodologia, empregando técnicas de estatística clássica, geoestatística e geoprocessamento, para o mapeamento da variabilidade espacial do potencial produtivo em um talhão com clones de Eucalypt us grandis, aos 6,3 anos de idade, e analisar sua relação com atributos do solo e do relevo, dentro de uma abordagem denominada Silvicultura de Precisão. A investigação foi conduzida numa área de 8,4 ha, com relevo acidentado, pertencente à Suzano Bahia Sul Celulose, em Paraibuna, SP. Foi instalada, na área experimental, uma gr
