Study on Individual Growth Models of Pinus Koraiensis

摘要

Before correct forest management decision is made, it's a core issue that gripping the forest stand structure and dynamic variation regularity, estimating the production capacity of stands and effects after adopting particular silvicultural technical measures in different site conditions. A variety of stand growth and yield prediction models are precisely to solve these problems to provide effective guidance. In this dissertation, through sampling and researching Meihekou forest stumpage data, the individual growth models of Pinus koraiensis were established, including the crown width growth prediction model and the crown length growth prediction model. These models can reflect the growth of individual growth state, but also the performance of the various factors affecting the growth, and provide a scientific basis for reasonable forest management.
