ABSTRACT: Research is presented that statistically analyzes the relationship between lake area and precipitation. These hydrologic variables are assessed in part using LANDSAT MSS satellite data and digital-image processing techniques. Results show dramatic regional hydrologic differences in lake area fluctuations and in lake area response to short term climatic variation. 相似文献

Federal land management agencies, such as the USDA Forest Service, have expanded the role of recreation partners reflecting
constrained growth in appropriations and broader societal trends towards civic environmental governance. Partnerships with
individual volunteers, service groups, commercial outfitters, and other government agencies provide the USDA Forest Service
with the resources necessary to complete projects and meet goals under fiscal constraints. Existing partnership typologies
typically focus on collaborative or strategic alliances and highlight organizational dimensions (e.g., structure and process)
defined by researchers. This paper presents a partner typology constructed from USDA Forest Service partnership practitioners’
conceptualizations of 35 common partner types. Multidimensional scaling of data from unconstrained pile sorts identified 3
distinct cultural dimensions of recreation partners—specifically, partnership character, partner impact, and partner motivations—that
represent institutional, individual, and socio-cultural cognitive domains. A hierarchical agglomerative cluster analysis provides
further insight into the various domains of agency personnel’s conceptualizations. While three dimensions with high reliability
(RSQ = 0.83) and corresponding hierarchical clusters illustrate commonality between agency personnel’s partnership suppositions,
this study also reveals variance in personnel’s familiarity and affinity for specific partnership types. This real-world perspective
on partner types highlights that agency practitioners not only make strategic choices when selecting and cultivating partnerships
to accomplish critical task, but also elect to work with partners for the primary purpose of providing public service and
fostering land stewardship. 相似文献

U.S. Forest Service managers are required to incorporate social and biophysical science information in planning and environmental
analysis. The use of science is mandated by the National Environmental Policy Act, the National Forest Management Act, and
U.S. Forest Service planning rules. Despite the agency’s emphasis on ‘science-based’ decision-making, little is known about
how science is actually used in recreation planning and management. This study investigated the perceptions of Forest Service
interdisciplinary (ID) team leaders for 106 NEPA projects dealing with recreation and travel management between 2005 and 2008.
Our survey data show how managers rate the importance of social and biophysical science compared to other potential ‘success
factors’ in NEPA assessments. We also explore how team leaders value and use multi-disciplinary tools for recreation-related
assessments. Results suggest that managers employ a variety of recreation planning tools in NEPA projects, but there appears
to be no common understanding or approach for how or when these tools are incorporated. The Recreation Opportunity Spectrum
(ROS) was the most frequently used planning tool, but the Visitor Experience and Resource Protection (VERP) framework was
the most consistently valued tool by those who used it. We recommend further evaluation of the strengths and weaknesses of
each planning tool and future development of procedures to select appropriate planning tools for use in recreation-related
NEPA assessments. 相似文献
