摘要

采集三峡库区忠县石宝寨4种不同土地利用类型土壤剖面0-40cm土层3个层次12个土壤样品

通过计算和测定土样颗粒体积分形维数及基本性质

以期说明三峡库区中性紫色土土壤颗粒体积分形特征及其与土壤基本性质间的相关性。结果表明

研究区中性紫色土土壤剖面(0-40cm)土壤颗粒体积分形维数D值介于2.638～2.674之间。随土层深度的增加D值总体呈增加趋势

不同土地利用类型之间的D值存在差异

表现为林地0.05mm)体积百分含量呈极显著负相关关系(P<0.01);D值与土壤有机质、全氮、全磷含量不存在显著相关性。

Abstract

For searching the characteristics of volume fractal dimension of purple soil particle in the Three Gorges reservoir region and the relationship between volume fractal dimension and the main features of purple soil

twelve soil samples from the four kinds of land use and three soil profiles within 0-40 cm depth were presented and tested

and the soil particle size distributions were measured by Mastersizer 2000.Some conclusions could be drawn as follows:The volume fractal dimensions of neutral purple soil(0-40...
