Description
Summary:The relationship between species diversity and ecotope diversity has long been debated. But these debates seem meaningless because most of them were based on different definitions. In this paper, diversity has two components: richness based on the total number and evenness based on the relative abundance. Species diversity is distinguished into individual‐counting diversity and biomass‐based diversity. Ecotope diversity is divided into individual ecotope‐counting diversity and ecotope‐area based diversity. Under this definition, we make a comprehensive investigation into Dongzhi tableland of Loess Plateau by cooperating with local technicians. We find that individual‐counting diversity is significantly correlated with biomass‐based diversity in grassland ecosystems; individual ecotope‐counting diversity and ecotope‐area based diversity have a significant correlation. Therefore, it is unnecessary to divide species diversity into individual‐counting diversity and biomass‐based diversity in grassland ecosystems and to distinguish ecotope diversity into individual ecotope‐counting and ecotope‐area based diversity for the issues that have no special requirement for accuracy. But the analyses of the investigation data demonstrate that species diversity has no significant correlation with ecotope diversity.
