Environmental quality of Korean coasts as determined by modified Shannon–Wiener evenness proportion

摘要: The coast of the Korean peninsula experiences a range human impacts, including pollution, shipping, reclamation, and aquaculture, that have motivated numerous local studies macrobenthic organisms. In this paper, 1,492 subtidal stations were compiled from 23 (areas) to evaluate environmental quality on broader scale. A common index in biomonitoring, Shannon-Wiener evenness proportion (SEP), could not incorporate azoic or single-species samples. This shortcoming was overcome by developing an inverse function SEP (ISEP), which positively correlated with independent measures water available for nine sites biased size sampling unit. Additionally, at Shihwa Dike, where samples collected before after reinstating tidal connection ocean, ISEP values improved over time, as expected. Thus, it is now possible assign seven "grades" use their trends guide coastal management.
