Abstract

A comparative study of systematic sampling and regression estimate for controlling total volume was conducted.The result implied that when doing regression estimate , the integrated information from sampling investigation and subcompartment investigation could be fully made use of to improve the precision for controlling the volume of forest management inventory .The efficiency of regression estimate was usually higher than systematic sampling .The utilization efficiency of the sampling statistics could be improved by regression analysis .The regression model could be used to monitor the quality of forest management inventory and correct the statistics of the forest management inventory .In addition , the systematic error could be adjusted by the regression mode so that the rejection and waste caused by systematic error could be avoided .[ Ch , 16 ref .]
