摘要:
针对土壤磁学在中国近海和河口城市的的研究相对比较缺乏的情况,本文应用土壤磁学的方法,按土地利用方式的不同,对日照市东港区的表土样品进行土壤粒度和土壤磁化率的实验.通过对土壤粒度与土壤磁化率进行皮尔逊相关分析,得到在土壤矿物组成基本相同的背景下,粘粒、胶粒的百分比与磁化率的相关系数为-0.576,粘粒、胶粒含量与土壤磁化率的相关系数在0.05水平上显著,呈负相关关系,砂粒含量与土壤磁化率呈正相关,粉砂含量与土壤磁化率呈负相关; 不同的农业土地利用方式以及土壤耕作措施对土壤质地与土壤磁性有不同的影响; 由粒度分析可看出在各采样点粘粒、胶粒所占的比例都是最少的,砂粒的含量相对较高.这是由于日照市属于正地形,在流水作用和风沙作用的影响下,使表土发育的细颗粒物质被带走,留下粗颗粒的物质的缘故.
Abstract:
There are few studies of soil magnetism in China's coastal and estuarine cities. The soil texture and soil magnetism in Donggang area of Rizhao City are studied according to different use with the method of soil magnetism. A Pearson correlation analysis of the clay content and soil magnetic susceptibility is made with the application of SPSS software. In the background of almost same soil mineral compositions, the correlative coefficient of clay content and soil magnetic susceptibility is 0.576, and their relationship is negatively correlated with a level of higher that 0.05. The sand content and soil magnetic susceptibility are positively correlated, while silt content and soil magnetic susceptibility are negtively correlated. Different ways of agricultural land use and soil tillage measures have different effects on soil texture and soil magnetism. The fine particulate in surface soil is taken away by water and sand in Rizhao, so in all sampling areas,clay content is minimal while sand content is relatively high.
