摘要：以重置成本法,按项目投资的财务效益评估手段,对马尾松中、幼龄林不同施肥处理的经济收益进行对比分析,结果表明:⑴幼龄林不同配比施肥处理的经济收益差异较大,经济收益以P2处理的最优,NP1处理的次之,K2处理的最差;⑵将P肥均分成2次施用到幼龄林的经济收益最佳(明显优于单次施入);⑶中龄林前17年生(施肥8年后)仍未达经济成熟;⑷中、幼龄林均以施P肥处理经济收益最佳。
Based on the replacement cost and the evaluation method of the project investment,the economic profits were compared among the middle-aged and young Pinus massoniana plantations with different fertilization treatments,the results showed that：⑴the young Pinus massoniana plantations with different ratio fertilizer treatments have distinctly different economic profits. In all the economic profits of the treatments,the economic profit from P2 treatment is the first,NP1 treatment the second,K2 treatment the last. ⑵in the young Pinus massoniana plantation,the treatment with P fertilizer divided equally into two halves gets the highest economic profits. ⑶all the middle-age Pinus massoniana plantations before the age of 17 years （ after fertilizing 8 years） haven＇t reached the economic maturity. ⑷by the treatment of P fertilizer,the economic profits of the middle-aged and young Pinus massoniana plantations were the highest in all the fertilization treatments.
