| Abstract: | The important features of forest resource inventory of BC Province of Canada are using the growth simulation system to predict fast growth and harvest, and using the geographic information system to show the current area of forests, thus revealing the role of a survey on the forest growth and harvest. Development of the prediction model is based on the data collected from the fixed and temporary sample plots for forest growth and harvest. This paper describes briefly the measuring technique and its characteristics. Emphasis is placed on describing the prediction method concerning forest growth and harvest, including the determination of the units of prediction, evaluation of site quality, compatible growth simulation system, and the principal prediction method. |
