The bifurcation of the Korean pine forest is not only very common in natural forests, but also in the plantations. In recent years, due to the small Hinggan Mountains and other places, into a piece of Korean pine forest bifurcation serious, dry bending, loss of its business value, serious losses, which attracted great attention. In order to understand the law of broussation and bifurcation of korean pine wood, the authors conducted a series of surveys on natural and artificial korean pine forests in areas such as Xiaoxing’anling and Zhangguangcailing. Now the survey is as follows. First, the environmental conditions of the Korean pine bifurcation (a) the slope and the relationship between Korean pine bifurcation 1 Korean pine natural forest
