Research on the relationship between stand productivity and site condition of Larix kaempferi

In this research, five plots are selected based on stand storage and productivity of planted forest of Larix kaempferi (Japanese larch) as well as their relationship with factors such as forest age, site condition and stand density. Through standard plot investigation and method of trunk analysis, systematic research is conducted on storage and productivity of the planted forest and their relationship with site condition. As shown in the research, productivity of planted forest of Larix kaempferi in low latitude area is higher than that in high latitude area while stand productivity is higher in slight acid soil. Contents of potassium element in the soil have considerable influence on productivity of the Larix kaempferi forest.
