摘要:

以国营雷州林业局纸浆材桉树人工林为研究对象,基于2015年1—2月调查的190块标准地数据,应用SPSS 19.0,ForStat 2.2软件,研究纸浆材桉树人工林生长与收获预估模型。结果表明:密度指数模型为SDI=1.7470No 1.0951 e - 3.7637 t 0.05 - 0.1742 L ;断面积模型为G=16.7828L 0.1529(1- e - 1.0125 × 10 - 8 SD I - 2.1970 t ) 0.5554;蓄积模型为M= e 2.3641 + 0.0988 L - 3.0557 t - 1 G 0.9126 。研究结果可为国营雷州林业局纸浆材桉树人工林生长收获预估、森林成熟龄确定以及森林资源管理提供理论依据。

Abstract:

The eucalyptus pulpwood plantation of State-run Leizhou Forestry Bureau was taken as the research object and the eucalyptus pulpwood plantation growth and yield model was studied based on the data of 190 sample plots surveyed in January to February in 2015. SPSS 19.0 and ForStat 2.2 were used.Results show that density index model is SDI=1.7470N0 1.0951 e - 3.7637 t 0.05 - 0.1742 L ,basal area growth model is G=16.7828L 0.1529 (1- e - 1.0125 × 10 - 8 SD I - 2.1970 t ) 0.5554,volume model is M= e 2.3641 + 0.0988 L - 3.0557 t - 1 G 0.9126 .The research results can provide theoretical basis for forecast of growth and yield,determination of forest mature age and forest resources management for eucalyptus pulpwood plantation in State-run Leizhou Forestry Bureau.

Key words: Eucalyptus pulpwood, plantation, SDI, growth and yield forecast
