广西国有高峰林场杉木人工林生物量的研究
|
摘要
以广西国有高峰林场5年生杉木人工林为研究对象,探究林分内的生物量。根据林分调查数据分析,研究结果如下:在8个同林龄的杉木林分中,每个杉木样地的单株生物量各不相同,说明杉木的生物量大小是由各个因素共同作用下的结果。杉木的枝下高和冠幅大小能明显地影响杉木树叶、活枝的生物量,其中又以冠幅的影响作用最大,杉木树高和胸径的大小能明显地影响杉木枯枝的生物量,而枝下高与冠幅对枯枝的影响很小。
Based on the peak of Guangxi state owned forest farms in a field of 5 year old Cunninghamia lanceolata plantation as the research object, to explore the biomass in the forest. According to the analysis of forest survey data, the results are as follows:In the Cunninghamia lanceolata forest stands, the biomass per plant of each fir plot is different, indicating that the biomass of Cunninghamia lanceolata is the result of various factors. The height of the branches and the size of the crown can significantly affect the biomass of the leaves and live branches of the Cunninghamia lanceolata, and the effect of the crown width is the largest. The height of the fir tree and the diameter of the breast can significantly affect the biomass of the Chinese fir. The height of the branches and the width of the crown have little effect on the dead branches.
