| 摘 要： | 侧柏疏林草原是陕北黄土高原森林草原地带东部重要群落类型之一,现仅残存于东北部的神府地区,常见者有4个类型:①茭蒿-侧柏疏林草原;②白草-侧柏疏林草原;③茭蒿+长芒草-侧柏疏林草原;④细叶柴胡+长芒草-测柏疏林草原。根据群落中乔木的更新状况分析,今后在气候不发生明显波动的情况下,侧柏疏林草原仍为该森林草原地带稳定的群落。

| Abstract: | The Platycladus orientalis open forest is the important one of the community-type in forest steppe zone of the loess plateau in northern Shaanxi Province, it survives only in Shenmu and Fugu county of northeast part, four types are often met: (1) Artemisia giraidii-Platycladus orientalis open forest; (2) Pennisetum flaccidum-Platycladus orientalis open forest; (3) Artemisia giradii+Stipa bungeuna-Platycladus orientalis open forest; (4) Bupleurum scorzoneri folium+Stipa bungeana-Platycladus orientalis open forest. According to analysis of the arborous regeneration, if climate doesn't happen great changes from now onwards, the Platycladus orientalis open forest is still stable phytocoenosium in forest steppe zone. |
