| Abstract: | Ground Plot Design techniques for National Forest Inventory(NFI) of major countries in the world are reviewed.They cover sample unit,plot configuration,plot size,selection of trees in sample unit,and investigation variables and interval.Clustered circular plots are commonly adapted.Forest health,biomass,biodiversity and soil carbon are also included in the investigation variables besides normal ones.The authors put forward corresponding suggestions on ground plot design of NFI in China based on existing problems. |
