摘要
通过对207块油松飞播标准地材料整理分析,编制了我省秦巴山区油松飞播林林分密度控制图。编图的理论精度,等直径线为95.58%,等树高线为95.42%。适用性检验结果也表明该图可应用于生产。
Through the analysis of 207 plots of Pinus tabulacformis air seeded plantation,the stand density control map was produced. The theoretical precisions of the map,for iso-diameter line is 95.58%,for isoheight line is 95.42%,the test result of suitability showed that the map can be applied in forestry production.
