What is Spatial Analysis and Ecosystem Classification?
Ecosystem classification is the identification, description, and logical ordering of relatively homogeneous basic units of nature--landscape or geographic ecosystems. Landscape ecosystems are structured, volumetric segments of earth space and not abstract entities or units defined by plant or biotic communities. Using multiple ecosystem components we distinguish ecosystem units from the continuity of the landscape and map them at multiple scales. Spatial analysis refers to the theory, methods, and technologies associated with proper handling and use of map-based data for the analysis and management of environmental problems and processes. Core technologies include geographic information systems (GIS), remote sensing, and spatial statistics.
Spatial Analysis and Ecosystem Management
Because ecosystem management is implemented on heterogeneous landscapes, it is necessary to characterize that heterogeneity and adapt management strategies that are sensitive to the spatial patterns and interactions. Ecosystem classification and mapping provide a concise overview of the spatial and volumetric structure of landscapes that can be used to support analysis and modeling of ecosystem processes and decisions about where various management approaches ought to be implemented. Spatial analysis involves the identification of spatial interactions on the landscape that characterize both the connections between various ecosystems and between ecosystems and human activity. Ecosystem classification involves a combination of field, photo and map based analysis, and is often complemented by computer-based analysis. The tools of spatial analysis are quantitative and computational. Methodological and technological developments in several areas support the work of spatial analysis, including remote sensing, geographic information systems, global positioning systems, and spatial statistics.
