Abstract
This study is designed to develop the site index curves using data for customized afforestation map production project based on the most appropriate height growth models which are also developed in the study of Betula platyphylla. In addition, it was intended to compare and analyze the index curve developed in the study and the index curve developed by the national policy. The results showed that the Gompertz function was suitable and the site index curve was shown as a sigmoid curve. As a result of comparing and analyzing developed the site index curve and the site index curve of the national, developed the index curve was more diverse. In addition, developed the index curve is a including geographical, ecological, and environmental influences of Jeolla-do. Based on the results of the study, it is expected that it will provide basic data for sustainable forest management and maintenance, and it provides the needs to develop the site index curve suitable for present stand grown by the region in South Korea.
Keywords : Betula platyphylla, height growth model, site index.
