摘要

Land development is one of the major anthropogenic processes shaping environmental sustainability. However, no standard method exists for evaluating this spatial process. This article proposes a method of modeling a spatially explicit representation of land development pressure, resorting to an inverse distance weighting interpolation. The study area encompasses four Macaronesian islands where land development has caused dramatic changes to the landscape: Sao Miguel, Madeira, Gran Canaria, and Tenerife. The method is demonstrated over 1990-2006, a period marked by a rapid increase in land development which ended with the 2007-2008 financial crisis. First, centroids of land change in/into artificial surfaces were used as a proxy of land development pressure. Second, these centroids were coupled with ancillary sampled points, which took into account a topographic resistance factor representing areas absent of land change. These ancillary points allowed for confinement of the interpolation values while acting as structural information for the rescaling of the interpolation into a higher resolution of a digital elevation model. The results show that the method captured the overall trend and magnitude of artificial land change. Quantifying and identifying the islands' pattern of land development pressure creates a variable that can play an important role in further modeling of anthropogenic spatial processes.
