A new method for estimating the carbon pool of forest ecosystems

Abstract

The proposed method is based on combining regression models for carbon conversion factors with the forest inventory data bank. Its specific feature is that the models for carbon conversion factors involve as regressors the same four volume-determining indices (age, site index, mean stem diameter, and stand density) according to which the stem volume data are assorted in the forest inventory data bank. This combining procedure was performed and the biases essential for the existing methods of the carbon pool estimation (compared to the proposed method) were calculated by means of a special program developed on the base of the PARADOX system of database control, DOS version 4.5, using as an example birch forests of the Nev'yansk forest enterprise in Sverdlovskaya oblast. © 1998 MAHK Hayka/Interperiodica Publishing.
