采用小波分析的方法对黑龙江省大兴安岭兴安落叶松林的林窗分布进行分析,研究结果表明:兴安落叶松林样带内计算林窗分布百分率小波变换的最佳尺度为10m 。林窗分布的疏密变化尺度为20m 左右,在样地中20×20m 2的小区域内具有较为稳定的分布特点。在样带中林窗分布呈斑块状,且斑块分布随样带的海拔的升高呈间断性分布。小波分析被证明是植被空间格局研究的简捷可靠的新方法。
The analysis of the gap distribution of Larix gmelinii forest in Daxing’anling of Heilongjiang Province by wavelet analysis shows that the best scale of the wavelet transform of the percentage distribution of gap distribution in Larix gmelinii forest is 10m. The variation of the density distribution of the forest gap is about 20m, and has a stable distribution in a small area of 20 × 20m 2 in the sample plots. In the transect, the forest window was patchy, and the patch distribution was intermittent with the elevation of the transect. Wavelet analysis has proved to be a simple and reliable new method to study the spatial pattern of vegetation.
