摘要
以重点调查与全面搜集已有研究成果相结合的方式 ,对杉木、马尾松人工林生产力现状与潜力 ,分别不同所有制、不同经营水平 ,进行了全面的调查研究。结果表明 ,集体杉木人工林现实生产力多为气候生产力的 11%～ 18% ,国有林多为 2 0 %～ 4 0 % ;若达正常经营状态 ,集体、国有杉木人工林其生产力可在现有水平上分别再提高 70 %以上和 4 0 %。集约经营条件下 ,杉木可达气候生产力的 50 % ,马尾松可达 80 %左右。良种、良法条件下 ,国有林生产力可在现有基础上再提高 80 %以上。相同条件下 ,马尾松同杉木相比 ,生物生产力高 2 0
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.
