Landscape ecology
Landscape ecology is the science of studying and improving relationships between ecological processes in the environment and particular ecosystems. This is done within a variety of landscape scales, development spatial patterns, and organizational levels of research and policy.〔Wu, J. 2006. Cross-disciplinarity, landscape ecology, and sustainability science. Landscape Ecology 21:1-4.〕〔Wu, J. and R. Hobbs (Eds). 2007. Key Topics in Landscape Ecology. Cambridge University Press, Cambridge.〕〔Wu, J. 2008. Landscape ecology. In: S. E. Jorgensen (ed), Encyclopedia of Ecology. Elsevier, Oxford.〕
As a highly interdisciplinary field in systems science, landscape ecology integrates biophysical and analytical approaches with humanistic and holistic perspectives across the natural sciences and social sciences. Landscapes are spatially heterogeneous geographic areas characterized by diverse interacting patches or ecosystems, ranging from relatively natural terrestrial and aquatic systems such as forests, grasslands, and lakes to human-dominated environments including agricultural and urban settings.〔〔Turner, M.G., R. H. Gardner and R. V. O'Neill 2001. Landscape Ecology in Theory and Practice. Springer-Verlag, New York, NY, USA.〕〔Forman, R.T.T. 1995. Land Mosaics: The Ecology of Landscapes and Regions. Cambridge University Press, Cambridge, UK.〕 The most salient characteristics of landscape ecology are its emphasis on the relationship among pattern, process and scale, and its focus on broad-scale ecological and environmental issues. These necessitate the coupling between biophysical and socioeconomic sciences. Key research topics in landscape ecology include ecological flows in landscape mosaics, land use and land cover change, scaling, relating landscape pattern analysis with ecological processes, and landscape conservation and sustainability.〔Wu & Hobbs 2002〕
== Terminology ==
The German term ''Landschaftsökologie''–thus ''landscape ecology''–was coined by German geographer Carl Troll in 1939.〔Troll, C. 1939. Luftbildplan und ökologische Bodenforschung (Aerial photography and ecological studies of the earth). Zeitschrift der Gesellschaft für Erdkunde, Berlin: 241-298.〕 He developed this terminology and many early concepts of landscape ecology as part of his early work, which consisted of applying aerial photograph interpretation to studies of interactions between environment and vegetation.
