辽东山区油松建筑材林立地质量评价研究
|
摘要
为评价辽东山区油松建筑材林的立地质量,以辽东山区大量不同立地条件下的油松人工林临时样地数据、解析木数据、油松人工林二类清查数据为依据,开展了辽东山区油松建筑材林划分标准与立地质量评价表的编制等方面的研究。结果表明:根据辽宁省用材林龄组划分标准和辽东山区油松人工林的生长过程,提出了辽东山区油松建筑材林按幼龄林、中龄林、近熟林、成熟林4个龄组,每1龄组分别划定了小径材、中径材、大径材3个径材规格的胸径分级标准。使用数量化理论Ⅰ方法计算出坡度、坡向、坡位、土层厚度、土壤质地、枯落物层厚度、腐殖质层厚度等7个立地因子所有水平的得分,编制出辽东山区油松建筑材林立地质量得分表;构建了7个立地质量数量化预测方程,并经χ2检验查表所得值与方程预测值无显著性差异;根据得分值范围编制立地质量等级评价表,辽东山区油松建筑材林立地质量由高到低分为Ⅰ,Ⅱ,Ⅲ,Ⅳ,Ⅴ共五级。为进一步与辽东山区油松建筑材林按龄组径阶划分标准相对应,使用Richard方程拟合了辽东山区油松人工林优势木树高与胸径生长曲线,构建了辽东山区油松建筑材林按胸径划分的立地质量等级评价表,并基于ArcGIS地理信息系统平台绘制了辽东山区3个地级市的油松建筑材林立地质量等级分布图。辽东山区油松人工林的立地质量大多为II,III,IV 3个等级,I级地块数量很少,没有V级地块,其中I,II级地块可以用来生产大径材,III级地块只可以生产中径材,IV级地块可以生产中径材和小径材。
Based on a large number of sample plots, stem analysis, forest management inventory under different site conditions,divided standard and site quality evaluation table was studied to evaluate the site quality of of Pinus tabulaeformis building timber forest in the mountainous area of eastern Liaoning Province. According to the classification standard of timber age group and the growth process of Pinus tabulaeformis Plantation, the DBH(diameter at breast height) grading standards of small, medium and large diameter timber was established for Pinus tabulaeformis building timber forest in the four age groups of young, middleaged, near-mature and mature forests in the mountainous area of eastern Liaoning Province. The scores of slope angle, slope aspect, slope position, soil layer thickness, soil texture, litter layer thickness, humus layer thickness at all levels of 7 site factors were calculated by using the quantitative theory I method, and the site quality score table of Pinus tabulaeformis building timber forest in the mountainous area of eastern Liaoning Province was compiled, then 7 quantitative prediction equations of the site quality were established. There was no significant difference between the predicted value and the measured value byχ2 test.According to the score range, the site quality grade evaluation table was established. The quality grade of Pinus tabulaeformis building timber forest in the mountainous area of eastern Liaoning Province was divided into five levels, which are expressed by Rome letters I, II, III, IV and V. In order to correspond to the DBH grading standard of age groups for Pinus tabulaeformis building timber forest in the mountainous area of eastern Liaoning Province, the growth curve of dominant tree height and DBH of Pinus tabulaeformis Plantation was fitted by Richard equation, the site quality grade evaluation table of the Pinus tabulaeformis plantation forest was constructed by DBH, and the quality grade distribution map of Pinus tabulaeformis was plotted based onArcGIS. The site quality of Pinus tabulaeformis Plantation was mostly II, III, IV grade. The number of I grade plots was very small, and there was no V grade plot in the mountainous area of eastern Liaoning. I and II grade plots can be used to produce large diameter timber, III grade plots can only produce medium diameter timber, and IV grade plots can produce medium and small diameter timber.
