Basing on the analysis of effect of Korean pine plantation for different tending-intermediate cutting and forest exploited both seed and timber, the result showed that it had obvious effect on cultivating large-diameter timber and increasing seed output by means of increasing tending-intermediate cutting strength and adopting pollarding measure.

The biomass, productivity and nutrient cycle of Larch plantation and Korean pine plantations in Boli of Heilongjiang Province were studied by selecting the similar stands in stand age, stand structure, site and management practices.
