| 摘 要： | 从地统计学角度，应用半方差维数对蒙古栎萌发的种子分布格局进行分析，结果表明：自然条件下蒙古栎的发芽率很高，幼苗难以越冬；在样地内，萌发的蒙古栎种子分布极不均匀，但在不同尺度下，半方差维数为1．820，其空间分布具有空间异质性．

| Abstract: | From the point of view of geostatistics, we researched the distribution configuration of germinal seeds with semirariance fractal. The results showed that: the germination percentage of seeds of Quercus mongolica was very high and the seedings were hard to get through the winter in the sample plot, the distribution of seeds of Querus mongolica was very homogeneous. but under different scale, semivariance fractal was 1, 820, so its distribution was characterized of space heterogeneity. |
