Based on the test of 23-year and 10-year old slash pine,this papersystematically studied the effect of different thinning intensity and different densityof plantation on the wood qualities and properties.Many statistical means such asanalysis of variance and cluster analysis were used to analyze the difference of thewood qualities and properties among the different silvicultural measures.

本文分别以23年生、10年生的湿地松为实验材料，全面地研究了不同间伐强度、不同种植树密度对人工林湿地松材质材性的影响规律，并利用方差分析、聚类分析等统计手段，定量地分析了不同栽培措施之间材质、材性的差异。

The nonlinear regression function of mathematic tool software SPSS was used to build models about DBH, high of tree, volume of single timber and stand volume slash pine plantation, and these models are have a certain extant applicability.

In comparison with slash pine, which was introduced earlier from abroad, and the native mason pine, the five-year-old loblolly pine families, which was introduced into Fujian Province, were evaluated.

火炬松原产美国东南部，是美国南方松类中极重要的速生建筑和纸浆用材树种，因其具备早期速生、适应性强等优良性状而被许多国家和地区广泛引种，作为工业原料林和用材林树种[1，2]。

The results were as follows: After the slash pine stands cover-overheaded, the average DBH and crown diameter are very negative correlative to stand density, the average high of branch and high of tree are a certain extent correlative to stand density; high stand density can be a certain extent accelerate high growth, but the effect is limited.

结果表明：湿地松人工林林分郁闭后，林木平均胸径、平均冠幅与密度呈极显著负相关；林分平均枝下高、平均树高与密度有一定程度的相关性，高密度一定程度上可以促进林木的高生长。
