An elementary study on the distributional rule of canopy gaps of Larix gmelinii forests using wavelet analysis
兴安落叶松(Larix gmelinii)林林窗分布规律的小波分析研究

The distributional rule of canopy gaps of Larix gmelinii forests in Daxinganling, Heilongjiang Province, was studied using wavelet analysis. The results obtained are as follows: The optimum scale of wavelet transformation for estimating the percent of gap distribution in transect of forests is 10 meters. That for variable density of gap distribution is about 20 meters. The gap distribution in small areas of 20×20m 2 in transects is relatively stable and tends to be fragmental and discontinuous with incre...
