Leaf area index (LAI) was developed to describe the number of layers of foliage in a monoculture. Subsequent expansion into measurement by remote-sensing methods has resulted in misrepresentation of LAI. The new name foliage layer index (FLI) is applied to a more simply estimated version of Goodall's "cover repetition," that is, the number of layers of foliage a single species has, either within a community or in monoculture. The relationship of FLI with cover is demonstrated in model communities, and some potential relationships between FLI and species' habit are suggested. FLI is a new formulation for the number of layers of foliage in a mixed-species' community. LAI should now be reserved for remote-sensing applications in mixed communities, where it is probably a nonlinear measure of the density of light-absorbing pigments.
叶面积指数（LAI）最初是为描述单一栽培作物中的叶层数量而提出的。随后扩展到通过遥感方法进行测量，这导致了LAI的误判。新名称叶层指数（FLI）应用于对古道尔“覆盖重复率”的更简单估算版本，即单一物种在群落内或单一栽培作物中的叶层数量。在模型群落中展示了FLI与覆盖度的关系，并提出了FLI与物种习性之间的一些潜在关系。FLI是用于混合物种群落中叶层数量的新公式。现在，LAI应保留用于混合群落的遥感应用，在这种情况下，它可能是光吸收色素密度的非线性度量。
