A Study On The Monetary Yield Estimate Model For Crytomeria Fortunei Plantation

The monetary yield estimate model can connected stand growing elements with the indexes of economic. It can offer the stand's output , corresponding monetary yield and dynamics change rule. The monetary yieldestimate model is divided into three kinds------individual tree monetary yield model,diameter distribution monetary yield model and whole-monetary yield model. These three kinds of monetary yield models are established by the gathering information and their bases are growth and yield models. Next ,density effect model which is based on monetary yield is established and how the density change influences individual tree's monetary yield is discussed .Then ,the result of how each the indexes of economic change influence individual tree monetary yield model and size-class distribution monetary yield model. Finally, the application of monetary yield model in the optimized control on Chinese Fir plantation density, the economic maturity and the assessment of forest resource assets is discussed in this paper.
