The Interior Northwest Landscape Analysis System (INLAS) project demonstrated a method for assembling teams of scientists to conduct integrated landscape analyses at the mid- or subbasin scale in the interior Northwestern United States. A state and transition modeling system (STM) with transition probabilities calibrated by using a stand-level silvicultural model to estimate rates of vegetative change was used as a central vegetative “modeling engine.” It connected to a variety of resource-related models including: wildlife habitat quantity, insect activity, grazing by ungulates, timber management, and wood utilization potential. Where appropriate, the study team examined other vegetation modeling approaches including an optimization approach based on heuristic methods and modifications to an existing stand-level projection tool, which was integrated with existing fire and insect behavior models. The STM approach provided a relatively simple interface for most resource models. These were connected to examine the influence of vegetative succession, natural disturbances, and management over a 100–200-year horizon under three management scenarios: (1) background natural disturbance, (2) fire suppression only, and (3) active fuel management. Taken all together, the results suggest to us: (1) maintaining abundant large-tree multistoried structure in cool, moist forest conditions is likely to be difficult, (2) both active fuel treatment and passive management scenarios increased the proportion of large-tree single-story forests in dry forest conditions, and (3) fire suppression only was least effective in producing and maintaining these “legacy” structures in either dry or moist forest conditions.  相似文献

Amenity values of forest environment are integrated into the planning of timber production with the help of computer simulation. In this way planners can evaluate the impacts of silvicultural management on the scenic value of a selected view. The assessment of the scenic value of landscape is based on figures drawn by the computer program and on an adjective sum, a numerical estimate of the amenity of the view. In addition to the scenic value, the simulation method gives an estimate of a great number of outputs associated with the simulated treatment regime, such as volume production, the value of harvested timber and the volumes of different assortments. The method can help the management of an individual stand. Because the impact of one stand in the landscape depends also on its surroundings, a method for evaluating several stands at the same time should be developed.  相似文献

Implementation of sustainable landscape policy directions can be held back by various constraints. These limitations may include: an absence of reliable integrated landscape character predictions, unproductive tensions arising from poorly informed public and institutional debate, low levels of political resolve due to uncertainty, and limitations on program and project design due to either inadequate availability, or ineffective use of ecological and social data. The need for new methodologies to speed the attainment of sustainable land use is pressing when considered in the context of information indicating that the condition of the world's ecosystems remains in decline. This decline is measurable by the changes in ecosystem services. Taking an ecosystem services view offers an opportunity to address some of the limitations noted earlier. The ecosystem services concept links natural resource management more clearly to the broader functionality of natural systems. Ecosystem services like clean water, productive soils and distinct flora and fauna are generated or maintained by healthy functioning ecosystems. Dwelling on these services and the practices that alter them defines the reasons for natural resource management. Modelling these ecosystems and their services is the key way to understanding these relationships. The utilisation of land use modelling methods to inform, and be informed by community and stakeholder landscape preferences, represents a potential step forward in the evolution of approaches to deliver sustainable landscape policy objectives. This paper presents a summary of examples of a multi-criteria land use optimisation technique that has been used to envision land use combinations most likely to achieve sustainable landscapes in Germany. A number of the sustainable landscape principles arising from Victoria's rural land stewardship project, such as use of an ecosystem services framework to better inform long-term land use planning along with calls to better connect community input to landscape function and land use decisions, are also considered.  相似文献

An important institution for regional resource governance is civic engagement in local affairs, including resource use issues. Local civic engagement has traditionally been structured around local government and, more recently, to catchment-based decision-making bodies. If citizens are to participate in regional resource management in ways that are meaningful to them, it is important that both the landscape units being discussed and the jurisdictional boundaries are meaningful. We have been examining how boundaries for resource management regions might be identified. Three considerations are believed to be important if regional resource management is to be meaningful to the citizens involved. Firstly, that the regional boundaries maximise the areal proportion of the region that residents consider to be part of their ‘community’, which should lead to greater commitment to civic engagement in resource management. Secondly, that the character of the landscape units within the region possess a high degree of homogeneity, reflecting greater coincidence of interest among the inhabitants of the region. The third consideration is a hierarchical multi-scaling capacity to deal with externalities of resource use. The approach was tested through identification of a series of nested ‘eco-civic’ resource management regions for north-eastern New South Wales in Australia. The results delineate resource governance regions that nest at local to regional scales for integrated natural resource management. Such ‘eco-civic’ regions demonstrate a better spatial representation of social and ecological characteristics than existing regional frameworks.  相似文献

Abstract

Landscape has become widely accepted as a concept for embracing the natural sphere as well as human society. There are, however, challenges in implementing the somewhat overarching rhetoric. This article takes a conceptual and deconstructive approach and elucidates complications in integrated landscape management, with a certain focus on landscape and time. Cases from some European areas, where integrative planning instruments are applied, serve as examples. The drawing of borders and the categorisation of areas are central aspects in understanding what constitutes integration, implying that negotiations and the weighing of different values are vital elements in integrated landscape management. Landscape management is inevitably an activity in the present, which is why landscape management needs to be based on good knowledge about the present conditions. In order to retain landscape qualities it is necessary to continuously reveal contemporary processes and reconsider and elaborate on functions and contexts that connect humans and their physical environment.  相似文献

The new community of Harmony, Florida stands out in the sustainable community landscape for its commitment to promoting the human–animal bond. Based on ethnographic fieldwork, this paper tracks Harmony's development from concept to community, and explores residents' perceptions and experiences of Harmony. Despite contradictions between philosophy and everyday practice, Harmony offers insights into the design of more sustainable communities built around ideals of human–animal coexistence – or “zoöpolis”.  相似文献

Rapid urbanization, as a result of population growth and migration from rural to urban, has been recognized as a critical process in urban areas. This study analyzed the spatiotemporal landscape dynamics using multi-temporal satellite images in two petroleum-based cities: Houston, Texas in the United States and Daqing, Heilongjiang province in China. Both cities expanded rapidly on the basis of the petroleum industries during the last 50 years; however, under different socio-political contexts. Comparing the landscape pattern and dynamics in these two cities, we can identify how the urbanization in these two petroleum-based cities affects the landscape pattern, especially in the natural landscapes. A set of landscape indices with supplementary ecological meanings was chosen to facilitate our analyses of spatial dynamics over a span of 20 years. On the basis of the derived indices, a general trend of landscape change was revealed in these two cities: natural landscapes such as grassland and wetland were degraded or fragmented into a more heterogeneous pattern, while the human landscapes such as residential area expanded greatly by replacing other natural classes.  相似文献

In landscape studies, at the turn of the twenty-first century, the concept of representation has been high on the agenda. Representation has often been understood as the expression of particular cultural politics of landscape, accentuating the socially biased and incomplete nature of textual and visual mediations of the world. In more recent work, it is possible to discern a shift from this emphasis on cultural representation to a fuller engagement with political representation. The concern here, crucially, is to understand representation as a core concept of justice, entwined with the social and material struggle over the right to landscape. In effect, to understand how landscapes materialise struggles over justice, an engagement with political representation is indispensable. As this paper elucidates, one potential consequence of the rediscovery of the political logic of representation is a rapprochement of landscape studies with environmental justice.  相似文献

Recent years have witnessed much debate on the turn towards community within landscape management and planning. This is particularly evident in the European Landscape Convention which asserts the legitimacy of local preferences and citizen involvement in policy processes. This paper explores a bottom-up perspective on people–place relationships in a changing landscape, through assessing the after-use potential of industrially mined peatlands in Ireland and the rehabilitation of degraded landscapes. The mining of the peatland resource has a longstanding tradition in Ireland, however, significant attention has now focused on exploring market and non-market uses of remains after harvesting has finished resulting in a cutaway landscape. We argue that local people's everyday experiences of the landscape is a legitimate form of knowledge and should provide a key input into deliberative planning and management processes. Drawing largely on an interpretive research approach, we assess key local narratives in relation to harvested peatland landscapes and explore local people's after-use preferences. There appears to be strong support among the local community for amenity/biodiversity after-uses, which are currently not reflected in public policy debates. We review people–place relationships and discuss the role of ethnographic research in a peatland context as well as defining the relevant stakeholders. Finally, conclusions are developed to identify wider lessons for people/place relationships within the context of landscape management and planning.  相似文献
