Abstract

Eucalyptus pulpwood plantation is the main forest type in Leizhou State Forestry Bureau.In this paper,based on the data collected 190 temporary sample plots which were investigated in January 2015 and getting rid of the sample plots with average height of superior trees having three times standard deviation,there are 164 standard sample plots which meet the requirements.Using sampling with equal probability to select 16 standard sample plots as testing data.The 9 models were compared by dummy variable guiding curve fitting method.The results show that the Logistic curve fitting effect is the best,and the difference between the observed value and the regression value is not significant in α=0.01.The standard age of Eucalyptus pulpwood Plantation is 2 years old,the distance of age-class is 4,index number is 8.The relatively advantage high method was used to calculate status index and impact testing showed that there were 160 standard sample plots in the site index table,accounted for 97.6%.Status index table can be a very good response to the site quality of eucalyptus pulpwood plantation in Leizhou State Forestry Bureau.
