摘　　要：The early growth of Pinus elliottii is rapid,so how to make Pinus elliottii generate economic benefit as quickly as possible is becoming increasing important.We conduct tapping test on man-made forest of perennial Pinus elliottii in Huashan forest farm,Huanjiang Maonan Autonomous County,Hechi City,Guangxi Zhuang Autonomous Region.The results show that the economic benefit of early tapping of Pinus elliottii is obvious,with high profitability;NPV(16 089.13)and IRR(39.2%)of forest stand tapped are much higher than that of forest stand not tapped;at the same time,it can bring considerable demand for labor,with good social benefits;tapping has a certain effect on the growth of Pinus elliottii,and turpentine production is closely related to the trunk diameter.The early growth of Pinus elliottii is rapid,so how to make Pinus elliottii generate economic benefit as quickly as possible is becoming increasing important.We conduct tapping test on man-made forest of perennial Pinus elliottii in Huashan forest farm,Huanjiang Maonan Autonomous County,Hechi City,Guangxi Zhuang Autonomous Region.The results show that the economic benefit of early tapping of Pinus elliottii is obvious,with high profitability; NPV( 16 089.13) and IRR( 39.2%) of forest stand tapped are much higher than that of forest stand not tapped; at the same time,it can bring considerable demand for labor,with good social benefits; tapping has a certain effect on the growth of Pinus elliottii,and turpentine production is closely related to the trunk diameter.
