Basin-scale vegetation (Chapter 12). In: Overton, I.C., Colloff, M.J., Doody, T.M., Henderson, B. and Cuddy, S.M. (eds). (2009). Ecological Outcomes of Flow Regimes in the Murray-Darling Basin. Report prepared for the National Water Commission by CSIRO Water for a Healthy Country Flagship. CSIRO

[摘要] This chapter presents a simple conceptual model of vegetation, as one component of ecosystem function, that is applicable to the entire Murray-Darling Basin, and demonstrates an application of the use of time-series satellite image data to measure changes in vegetation, within the context of this framework, at a range of spatial and temporal scales. The outline and design of the conceptual model is presented in Section 12.2, including descriptions of its four basic components: flow/connectivity, productivity/metabolism, habitat and disturbance. The analysis of satellite images to assess changes in vegetation commences in Section 12.3. This analysis interprets a time series of Normalised Difference Vegetation Index (NDVI) images from the MODIS sensor in terms of changes in vegetation biomass and/or productivity due to climatic conditions and water resource development levels. This work is conducted at two scales: within reporting regions defined for the Murray Darling Basins Sustainable Yields (MDBSY) analysis (CSIRO 2008), and within each of the 93 eco-hydrological zones defined for this project
