Agricultural Land Fragmentation at Urban Fringes: An Application of Urban-To-Rural Gradient Analysis in Adelaide

摘要: One of the major consequences expansive urban growth is degradation and loss productive agricultural land agroecosystem functions. Four landscape metrics—Percentage Land (PLAND), Mean Parcel Size (MPS), Density (PD), Modified Simpson’s Diversity Index (MSDI)—were calculated for 1 km × cells along three 50 km-long transects that extend out from Adelaide CBD, in order to analyze variations structures. Each transect has different uses beyond built-up area, they differ topography, soils, rates expansion. Our new findings are zones fragmentation can be identified by relationships between MPS PD, these occur areas where PD ranges 7 35, regardless distance transect, use, or growth. This suggests a geometry may consistent, indicates quantification both use land-use change potentially important planning.
