Abstract: The present conditions and the potentialities of forest plantation productivities of Cunninghamia lanceolata and Pinus massoniana, with different ownerships and different mangement intensities.were studied.The results showed:(1)The present productivities of the collective ownership and the state owned forest plantation are 11%~18% and 20%~40%.(2)In normal management state,the productivity of the collective ownership forest plantation will be raised over 70% based on its present productivity,and the state owned forest plantation will be raised by 40%.(3)In intensive management, Cunninghamia lanceolata forest plantation will be 50% of the climatic productivity,and Pinus massoniana will be 80% of the climatic productivity.(4)In using good strain and scientific cultivating,the productivity of the state owned plantation will be raised over 80% based on its present productivity.(5)In the same management condition,the productivity of Pinus massoniana stand is 20% higher than that of Cunninghamia lanceolata.
