摘要：米老排（Mytilaria laosensis Lecomte）又名壳菜果、三角枫,为金缕梅科常绿乔木树种,天然分布于我国广东、广西和云南省区以及越南和老挝等地,具有速生、干形通直圆满、材质优良,兼具改良土壤、保持水土等优点,是建筑、家具、造纸和人造板的优质原料。鉴于该树种的优良特性及广泛用途,已有学者对其进行了育种、栽培、木材材性及利用开发等基础应用研究；
In this paper,on the basis of the survey of 3 standard sample plots and the stem analysis of 7 trees,and collecting the local technical economic indicators,the replacement cost method was used and the economic indicators of average annual profit,net present value and internal rate of return were selected to evaluate the economic benefits of 28-year-old Mytilaria plantation in Fubo Experimental Field,Experimental Center of Tropical Forestry of Chinese Academy of Forestry,which locates at Pingxiang city of Guangxi Zhuang Autonomous Region.The results showed that： With the increase of forest age,the annual profits could increase every year,the average annual profit and revenue of the 28th year were respectively as high as 155 366 yuan·hm-2 and 5 549 yuan·hm-2;the investment became profitable in the 15th year,as a whole net present value increased at first then declined,the peak appeared in the 23rd year;the movement of internal revenue was similar to that of the net present,rising firstly and then declining,the peak appeared in the 18th year;based on the maximum net present basis for determining,the economic maturity age of Mytilaria plantation was in the 23rd year,when the average annual profit,net present value and internal rate of return were respectively reached 4 593 yuan·hm-2,11 392 yuan·hm-2,and 11.4%.This means the management of Mytilaria plantation can obtain higher economic return.
