长白山3种主要林型林分生长过程研究
DOI: 10.3969/j.issn.1000-2006.2014.02.013, PP. 63-67
Keywords: 云冷杉林,杨桦次生林,落叶松人工林,林分生长模型,长白山
Abstract:
利用924株冷杉、844株云杉、183株白桦、158株山杨和227株落叶松解析木的数据,建立了长白山优势树种的直径生长方程。在相同的立地条件下,利用长白山245块云冷杉林、32块杨桦次生林和260块落叶松人工林固定样地,结合优势树种的直径生长方程,分析了长白山3种主要林型林分的平均直径、树高、单位面积林木平均株数和蓄积的生长过程。另外,用未参与建模的28块云冷杉林、4块杨桦次生林和30块落叶松人工林固定复测样地对拟合的3种林型林分生长过程模型进行检验,结果显示预估的相对误差为3.26%～4.96%,估计精度为95.04%～96.74%。
