单一斜率变点分析格氏栲幼苗的竞争范围
DOI: 10.3724/SP.J.1145.2012.00847, PP. 847-852
Keywords: 格氏栲,幼苗竞争,竞争范围,单一斜率变点,林窗
Abstract:
依据改进hegyi单木竞争模型计算林窗和林下不同龄级格氏栲幼苗的竞争强度，采用指数平滑模型对幼苗竞争强度数据进行优化，对优化后数据应用单一斜率变点法确定格氏栲幼苗最佳竞争范围.结果表明：1）在格氏栲天然林中，林窗和林下格氏栲幼苗平均竞争强度随着竞争距离增大而逐步降低，初期下降较快，下降到一定程度后明显变缓，存在变化幅度的转折点，即为幼苗的竞争范围.2）林窗和林下格氏栲幼苗竞争强度的三次指数平滑值在最佳平滑系数α为0.8和0.7时其均方误差值分别为0.4015和0.3851，单一斜率变点分析得出林窗和林下格氏栲幼苗最佳竞争范围分别是距对象木1.70m和1.90m.研究结果可为格氏栲幼苗竞争格局研究中确定幼苗竞争范围提供科学理论依据.表3参20
