摘要:
以分形理论对闽南山地造林密度分别为1 125、1 225、1 325、1 625和2 225株/hm2的桉树人工林土壤结构和理化性质进行研究,建立桉树人工林土壤水稳性团聚体含量与其分形维数相关关系式,以及土壤水稳性团聚体的分形维数和对应的土壤理化性质指标的回归模型。研究结果表明,桉树林土壤水稳性团聚体的分形维数与土壤水稳性团聚体含量及理化性质呈显著回归关系,土壤水稳性团聚体含量与分形维数呈负相关。造林密度为1 325株/hm2的桉树林土壤水稳性团聚体的分形维数最小,林地水稳性团聚体含量最高,土壤结构和稳性性最好。分形理论在林地土壤肥力研究上的应用为林地评价提供了新方法。
Abstract:
The fractal theory was used to study the soil structure in different density include 1 125，1 225，1 325，1 625 and 2 225 tree/hm2 of Eucalyptus plantation in south Fujian mountain. The regression model between the fractal dimension of soil waterstable aggregate constitution and the soil physicochemical properties was build. The results were as follows. The soil fractal dimension showed significant regression relationships with physicochemical properties，specially，showed negative correlation with the content of≥0.25 mm soil waterstable aggregate constitution. The fractal dimension of soil waterstable aggregate structure in density of 1 325 tree/hm2 of Eucalyptus plantation was the least，which showed the best in structural stability and fertility status. Application of the fractal theory on the forest soil fertility provides a new method for forest assessment.
