Robust estimation and analysis of investigation data in forest resource.

Liang Changxiu; Feng Zhongke; Lang Nanjun; Huang Huaguo; Zhou Keliang.College of Resource and Environment,Beijing For.Univ.,100083,P.R.China.  
In the survey of forest management previously, the statistic relationship between the photo interpretation volume of the plot and the practical measurement is based on the classical principle of MLS. If there is no gross error in the data of survey, MLS estimation can show people good results. Therefore, because of the effect of a variety of factors, there are always some errors left in the results. With the help of Robust estimation, more accurate result can be obtained from the data including rude errors.
