侧柏是泰山的主要树种之一，其可持续发展对泰山森林生态环境的保护和发展具有重要意义。本研究在泰山上选择了大小为30 m * 20 m的具有代表性的侧柏样地。在样地内调查了侧柏母树和苗木的生长和分布情况。结果表明：在一定尺度范围内，样地内母柏树和苗木均呈聚集分布格局，符合大多数自然群落的分布规律;母柏在一定尺度范围内具有促苗作用。虽然侧柏具有良好的天然更新能力，但单纯依靠天然肥力进行林下更新很难成功，不利于林分的长期稳定发展。因此，对侧柏林进行间伐，调整林分结构，人工促进天然更新，不仅可以降低经营成本，而且符合森林近自然经营的思想，保持森林可持续发展。
Platycladus orientalis is one of the main tree species in Mount Tai, and its sustainable development is of great significance to the protection and development of the forest ecological environment of Mount Tai. In this study, a representative sample plot of Platycladus orientalis with a size of 30 m * 20 m was selected on Mount Tai. The growth and distribution of the parent trees and seedlings of Platycladus orientalis were investigated in the sample plots. The results showed that both the mother cypress trees and seedlings inside the plot present an aggregated distribution pattern within a certain scale, which conforms to the distribution of most natural communities; and the mother cypress can promote seedlings within a certain scale. Although Platycladus orientalis has good natural regeneration ability, it is difficult to succeed in understory regeneration solely relying on natural fertility, and it is not conducive to the long-term stable development of forest stands. Therefore, the thinning of Platycladus orientalis and the adjustment of the forest stand structure and artificial promotion of natural regeneration can not only reduce operating costs, but also conform to the idea of forest near-natural management and maintain sustainable forest development.
