| 摘 要： | 根据福建省森林资源连续清查第4和第5次复查资料,研究了福建省天然阔叶林分布格局并进行了动态分析.结果表明,福建省阔叶林大多分布在地形陡峭海拔较高处,但坡位不高,这种分布状况较为稳定;林中大多为小径材林且中幼林较多,年龄结构不合理,林分低龄化明显,但有向合理结构发展的趋势;在坡位、坡向、土壤厚度上的分布较为稳定.总体上福建省阔叶林面积和蓄积量变化不大.

| Abstract: | The data investigated in the fixed plots located in Fujian Province were analyzed from the fourth and the fifth countercheck to reveal spatial distribution pattern and dynamics analysis of broad-leaved forest. The results indicated that the broad-leaved forest was mainly distributed in steep slope and high altitude. Forest stands contained young, immature and old trees all together, but the age structure was irrational. But the forest stands will become rational gradually. However, the distribution of broad-leaved forest was steady on slope, exposure and soil stratification, which will change little in short time. In the general, it showed that the volume change of broad-leaved forest was steady. |
