Abstract
According to the cultivating practice ofLarix olgensis pulp plantation, IRR (Internal revenue rate) and NPV (Net present value) were taken as two economic indices to study the effect of cultivation measurements on economic benefit ofLarix olgensis pulp forest. The results showed that the economic benefit of this type of forest is closely related to rotation and site class. Higher economic benefit could be obtained when the rotation is shorter and site class is higher. The planting density also had an obvious influence on economic benefit. On the base of assuring survival rate and conserving rate, the less the fee used in soil preparation and young growth tending is, the higher the economic benefit is. The influence of determined six cultivation measures on economic benefit in sequence was the rotation—site class—density—management fee level—young growth tending intensity—soil preparation methods.
