| Abstract: | Based on a survy on Betula alnoides plantation of 1997 to 2010, the Betula alnoides plantation area was 83, 810hm^2 in Dehong Prefecture, Yunnan Province. Randomly choosing 72 sampling plots in which 14 trees were taken to estimate the timber volume, results showed that timber storage was 4, 606, 500 m^3 among 83, 810 hm^2 plantation. The average tree age of mature forest would be 20 year, average DBH could grow to 26 cm, and the timber volume was up to 34, 674, 000 m^3 , the output value would be 350 hundred million Yuan. Unit area output could be 416, 800 Yuan pur hm^2. The economic benefit would be significant. |
