Ecosystem Analysis

Some methods of ecosystem analysis emphasize the measurement of short-term process rates (e.g., photosynthesis, nutrient uptake, and evapotranspiration), whereas other methods emphasize the measurement of the size of pools accumulated as a result of these processes, with or without consideration of their internal components (e.g., biomass production, nitrogen stocks …

Eight energy and material flow characteristics of urban ecosystems

The concept of urban metabolism has been widely used to study energy and material flows into and out of cities, with a rapidly growing body of literature over the last 10 years (Decker et al. 2000; Warren-Rhodes and Koenig 2001; Kennedy et al. 2007; Zhang and Hu 2011) has started as a metaphor of likening cities to a living organism, and while there are …

Nevertheless, …

Ecosystem Flow Analysis

The motivation for flow partitioning begins with nondimensional flow intensities (i.e., throughflow-specific flows) which result when flows are divided by throughflows of originating compartments: g ij = f ij /T j.The elements of matrix G = (g ij) give the dimensionless transfer efficiencies corresponding to each direct flow, f ij.Powers G m of this matrix give the indirect …
