Abstract

Subcompartment data updating is required in local forest resource monitoring , and the prerequisits of its realization are to build up both dynamic database and data updating models for the subcompartments .This paper stresses on the latter in which the modelling of real forest stands is dealt with and a great amount of partial cutting took place among them .Based on little variation adjustment , a phase-varied growth model technique is presented .And through its use , annually accumulated and magnified errors is removed and the reliability of subcomparment data updating is improved .

- data updating,
- dynamic database,
- forest stand,
- standing crop,
- mathematical models,
