Evaluating optical measurements of leaf area index against litter collection in a mixed broadleaved-Korean pine forest in China

Key messageWe evaluated the error caused by optical measurements of leaf area index using a direct method in a mixed broadleaf-coniferous forest in China.AbstractIndirect optical methods to measure leaf area index (LAI) have been previously developed, but it is difficult to evaluate the accuracy of these methods in a mixed broadleaf-coniferous forest. In this study, the LAI in a mixed broadleaved-Korean pine (Pinus koraiensis) forest in China …
