Food chain length is a significant ecosystem index and it greatly affects processes their outcomes. In recent decades, determinants or indicators of FCL have been investigated in different ecological contexts, but few studies analyzed the relationships between macrophyte community structure food freshwater ecosystems despite crucial role determining web structure. This study influence on by conducting field survey Lake Poyang, largest lake China. Plant volume inhabited (PVI), Shannon-Wiener diversity Pielou's evenness were used to indicate Our results suggested that intermediate levels PVI (PVI 44% 0.61) with greater could support longer sub-lakes Poyang. We proposed indexes be useful indicating ecosystem. These novel findings also highlight within suitable ranges diversity, better restoration effect achieved higher management. provide new insights for management macrophytes ecosystems.
