艾比湖流域土壤机械组成测定与分析

The Soil Mechanical Composition Determination and Analysis in The Ebinur Lake Basin

土壤机械组成是构成土壤结构体的基本单元[1],土壤机械组成决定土壤保肥蓄水和通透性能。土壤机械组成,不仅是土壤质地分类、命名的基础,而且直接关系着土壤松紧程度、孔隙数量,进而影响着土壤通气、透水及土壤环境背景值、能量转化等性能,是评价土壤基本性质和形成环境的一个重要指标[2]。文章针对艾比湖流域的土壤机械组成进行测定和分析,通过对其研究为当地的农业土壤改良和防止土地沙化提供一些科学性的参考。

The soil mechanical composition is the basic unit of soil structure, soil fertilizer and permeability to water are decided by it. It is standard not only soil texture classification and the naming foundation of the soil, but also direct relation on the extent of the soil elastic, pore number, thus is affecting the ventilation of the soil , the water percolation and environmental background values of the soil and energy conversion. It is an important indicator to evaluate the fundamental property and the environment of the soil forms. In this paper, by determination and analysis the soil mechanical composition of the Ebinur Lake Basin, given some scientific reference about transformation of agricultural soils and the prevention of land desertification.
