摘要

在丹江鹦鹉沟小流域利用典型样地取样法

进行土样采集

共选取78样点

测定土壤4个不同深度的养分含量。应用传统统计学和地统计学的方法

对不同深度土壤总氮含量进行了分析。结果表明:土壤总氮含量均值、最大值和最小值均表现为A1>A2>A3>A4

随土壤深度的增加而降低。经Kriging插值分析

由A1到A4总氮分布逐渐由小的斑块向大的斑块转变

总氮变化范围逐渐变小

同时A1土壤总氮含量表现为农地

Abstract

By means of typical spot samples

78 soil spots were chosen in Yingwugou watershed.The contents of soil nutrient were determined for each soil sample of 4 different soil depths.Both traditional and geostatistics methods were applied to analyze TN in 4 different soil depths.The results indicated that TN contents(mean

maximum

minimum) were all A1>A2>A3>A4.With the increasing of depths

the TN content reduced.The Kriging interpolation shown that the TN from A1 to A4 changed from small patches to large patches an...
