位于广西南宁的高峰林场是我国重要的林木种植基地,其中,桉树人工林的种植为林场带来了重要的经济效益。但是,桉树人工林的生长周期短,连栽频率高,其生长土壤与其他树种人工林之间的土壤便存在着较大的差异。分析桉树人工林与其它树种人工林之间土壤差异性程度,并归纳找出原因,对有效提高桉树人工林的土壤肥力、维持按树人工林的土壤肥力,确保高峰林场的经济效益与生态效益,有着重要的作用。本文也将从土壤结构和养分状况的角度,提供可参考的理论依据,基于经济效益与生态效益兼顾的角度,为按树人工林可持续经营提供可参考的依据。
Gaofeng Forest Farm, located in Nanning, Guangxi, is an important forest planting base in China. Among them, the planting of eucalyptus plantations has brought important economic benefits to the forest farm. However, Eucalyptus plantations have short growth cycle and high frequency of continuous planting, and there is a big difference in the soil between their growing soil and other tree plantations. Analyze the degree of soil difference between plantations of eucalyptus plantation and other tree species, and find out the reasons, which can effectively improve the soil fertility of eucalyptus plantation, maintain the soil fertility of tree plantation and ensure the economic benefits and ecological benefits , Has an important role. This paper will also provide a theoretical basis for reference from the perspective of soil structure and nutrient status. Based on the consideration of both economic benefits and ecological benefits, this paper will provide a reference for the sustainable management of tree plantations.
