Abstract: Equations for estimating diameter distribution, growth, and yield were developed based upon measurement of 230 temporary plots located in natural Dahurian larch Larix gmelinii stands throughout Daxingan mountains. First of all, equations for projecting stand density (basal area or number of trees) and stand volume from stand condition and growth model of basal area were developed using regression analysis technique. Compatible models of estimating diameter distribution—parameter recovery model (PRM) were derived by solving for the parameters of the generalized form of gamma distribution from attributes predicted with the stand-level models. A mathematical compatability exists between two yield forecasting techniques: diameter distribution models and stand-level models. A new method is presented for editing yield table.
