凉山州植烟土壤颗粒表面的分型特征研究
摘 要：为了解植烟土壤颗粒表面的分形维数D的特征变化规律，以凉山州会理县的植烟土壤为例，研究了不同质地耕层土壤颗粒表面的分形维数（D）特征及其与土壤质地、粒级、有机质及全量养分含量之间的关系。结果表明D介于2.1494~2.8330之间，同一质地类型的土壤分形维数D差异比较大，随土壤质地由紧砂土、砂壤土到轻壤土，分形维数D呈递增趋势；土壤颗粒表面的分形维数D与各粒级颗粒含量之间存在极显著的线性回归关系；各粒级对分形维数D的直接贡献由大到小依次为：粘粒>砂粒>粉粒，无论哪一个粒级的颗粒含量增加，通过其它两个粒级的颗粒含量的间接效应都将使分形维数D增大；土壤有机质含量、土壤全氮含量分别与D有极显著正相关，而土壤全磷含量、土壤全钾含量分别与D有极显著负相关。土壤颗粒组成及全量养分含量等对分形维数D能产生极大的影响，通过对它们之间关系的分析，可以为土壤理化特性的综合定量评定提供科学依据。
关 键 词：土壤颗粒组成；土壤质地；分形维数特征

Answer 1

The surface of liangshan prefecture of soil particle of research
Pick to: for understanding the soil particles on the surface of the fractal dimension characteristic of D, HuiLiXian liangshan in the soil, for example, the different soil particles on the surface of the field quality fractal dimension (D) and its characteristics of soil texture, grain, organic matter and the quantity of the relationship between nutrient content. Results show that 2.1494 between 2.8330 ~ D the same texture types, between the fractal dimension of soil, with differences between D by the tight sand soil texture, sandy loam to light loam, fractal dimension D increasing trend, Soil particle surface fractal dimension of each grain grade D and particle concentration significantly between the linear regression, Each grain of fractal dimension of the level of direct contributions by large D to small as follows: > > sand viscous grain powder, no matter what a grain of particles increases, the content of two other grain by grain content of indirect effects will make the fractal dimension D, Content of soil organic matter, total nitrogen content of soil and D have very significant positive correlation, and soil phosphorus content, soil total potassium content and a significant negative correlation D. And the amount of soil particle nutrient content on the fractal dimension D can produce great influence on them, through analysis of the relationship between soil physical and chemical properties, the comprehensive quantitative assessment provides scientific basis.
Key words: shut soils, The soil texture, Fractal dimension
