张掖市北郊湿地土壤有机质与全氮、全磷的相关性分析

湿地是一类特殊的生态系统,其独特的环境及生物地球化学过程孕育了特殊的土壤类型。以实地调查及分析测试数据为基础,在张掖市北郊湿地区域内,通过同一深度水平方向上和不同取样点垂直方向上的有机质与全氮的线性相关分析,表明二者的相关性十分显著,利用确定的相关方程,可直接用湿地土壤中全氮的数值来推测有机质的含量;而通过对有机质与全磷数据的分析,表明二者在区域内没有线性相关关系。

Correlation Analysis of Soil Organic Matter and Total Nitrogen, Total phosphorus in the wetland of the northern suburbs in Zhangye city

The Wetland is a special Class of eco-system,its unique environment and bio-geochemical processes bred a special type of soil.The artiCle is based on the field survey and analysis test data,in the wetland of the northern suburb in Zhangye city,through the horizontal direction in same depth and different sample points in perpendicular on the linear correlation analysis between organic matter and total nitrogen,it shows that the correlation between the two is very significant.It takes the established equations and directly uses the total nitrogen value in the wetland soil to guess the content of the organic matter.Otherwise,it also is based on data analysis of organic matter and total phosphorus and indicates there is on linear correlation between the above two in the area.
