Abstract

This study compared 2 strategies, including a high-resolution-data-based resampling (RS) approach and a multisource and multiresolution data (MSMRD) approach, to quantify the grain effects of 9 commonly used landscape metrics determined by FRAGSTATS software. Three adjacent, small watersheds in the central Loess Plateau of China were selected as study sites. Using the RS and MSMRD approaches, 5 and 7 landscape metrics, respectively, were detected to have significant and mostly linear grain effects. This paper also highlights gaps in present scaling research on landscape metrics by their numerical responses to grain sizes, with the conceptual and mathematical formulations largely neglected
