| 摘 要： | 通过对2001年人工模拟林窗的调查,得出霍山地区山地灌丛林窗恢复的早期动态及环境特征,初步分析了林窗内植物的来源和地下生物量。表明,在彻底破坏的模拟林窗内,先锋植物多为阳性,在破坏程度较小的林窗内趋向于恢复原状植被,且恢复速度快。从林窗中心林窗边缘非林窗,地表温度逐渐下降,地表湿度未出现一定梯度。林窗内的植物来源有三种:林窗原有植物根、枝或残留种子,以及外来因素随机带入的种子。由地表向下(至土深60cm),地下生物量递减,成倒金字塔形。

| Abstract: | Through the investigation on gap simulation in the year of 2000,early trends and environmental situation of shrub gap resumption in the hilly region of Huoshan were obtained,the origin of plants and under-ground biomass in gab were analyzed.The results showed that,pioneer plants seemed positive in the gap broken completely,However,in the gap broken to some extent,vegetation was tend to restore rapidly to original state.The earth's surface temperature gradually decreased from the middle of gap to the edge to no-gap,yet the earth's humidity kept steadily.There were three originations of plants in the gap,that is the roots or twigs of original plants,remained seeds,and the seeds randomly brought by outside factors.The underground biomass decreased progressively into the inverted pyramid-shape from the surface to under-ground(the depth of 60 cm) |
