摘  要:
Using the value index of net present and the internal rate, this paper make dynamic and static economic evaluation on Cryptomeria japonica plantation. The results show that: the total investment of reforestation project reached 305496.01 yuan / hm~2 in 31a Cryptomeria japonica plantation, the profit rate of total investment was 39.44%, the net present value was approximately 832.72 yuan / hm~2, the overall economic level was higher than the local native species; the internal rate of 26 a Cryptomeria japonica plantation was the highest(13.55%); cedar wood price was higher than the price of breakeven point(307.96 yuan / m~3), and cedar wood price was the most sensitive factor to affect the economic benefit in Cryptomeria japonica plantation. In summary, the economic benefit of Cryptomeria japonica plantation project investment is high, the investment risk is small, the market demand is great, and the best optimal rotation age is the 26 year, so cryptomeria japonica plantation is suitable for planting in Guangxi province.
