Estimating Aboveground Biomass of Submerged Vegetation Using Landsat 5 TM Imagery: a Case Study of Jiangxi Poyang Lake National Nature Reserve,China

Firstly,the methods used to estimate the aboveground biomass of submerged vegetation are briefly reviewed.Secondly,on the bassis of the reviewing,the process using Landsat 5 TM imagery to estimate aboveground biomass of submerged vegetation in Jiangxi Poyang Lake National Nature Reserve is discussed in detail.The results showed that it was infeasible to estimate the aboveground biomass using Landsat 5 TM imagery combined with traditional field sampling method and computation technologies in this particular study area.Finally,the reasons causing this infeasibility were analyzed,and suggestions for future research were presented.
