摘　　要：侧柏人工林在山东省生态建设中发挥了重要作用,但目前多数林分由于长期密度大、郁闭度高,导致生态稳定性较差,急需采用适当抚育措施进行合理调控,以构建稳定的森林生态系统。研究发现,林分密度、郁闭度、土壤水分、坡向、土壤速效钾含量和阳离子交换量等是影响侧柏人工林生态稳定性指数的重要因素。因此,提出了间伐、修枝、修建集雨池、选择适宜坡向、合理施肥等多项措施作为侧柏人工林稳定生态系统构建技术。Platycladus orientalis plantation plays an important role in the ecological construction of Shandong province,but at present,most of the long-term stands have poor ecological stability due to their high density and high canopy density,so it is urgent to adopt scientific and effective tending measures to reasonably regulate and control in order to build a stable forest ecosystem.It was found that soil moisture,stand density,canopy density,slope direction,soil available potassium content and cation exchange were important factors affecting ecological stability index.Therefore,some measures,such as thinning,pruning,rainwater harvesting,selecting suitable slope direction and reasonable fertilizer application,are put forward to construct stable ecosystem of Platycladus orientalis plantation.
