Abstract

Abstract: The investment risk assessment of 18-year-old Pinus massoniana Lamb. plantation was carried out in order to provide reference for the cultivation and promotion of the tree. The risk assessment of the investment projects was carried out by means of dynamic sequence analysis, sensitivity analysis and static profit and loss analysis. The results showed that the internal rate of yield reached to 41.75% in the 18-year-old P. massoniana plantation. The financial net present value of the investment project was 64 593.86 CNY/hm², the timber income was 123 850.52 CNY/hm², the income of the turpentine was 481 493.42 CNY/hm², and the profit was 316 713.98 CNY/hm². The investment project of P. massoniana plantation is the most sensitive to the price of turpentine. The internal rate of return was the highest in the 14^th year（at 45.26%）, when it reached to the maturity stage and was also the best time for cutting. In conclusion, the investment economic profit of P. massoniana plantation project is large and the risk is small, thus is suitable to be promoted in Guangxi.

Key words: Pinus massoniana Lamb., plantation, investment risk, assessment, economic benefit
