英文文献：Environmental Values And The Optimum Rotation Problem In Forestry Economics
英文文献作者：Nguyen, Dung
英文文献摘要：
The model shows that, even for a forest that provides environmental services, it is always optimal to harvest, and the optimum harvesting age must be somewhere on the rising portion of the growth curve. Furthermore, an analysis based on the economist's criteria would not necessarily result in a much shorter cutting age compared to the forester's optimum.
