| 摘 要： | 利用强大的数据计算分析软件MATLAB和统计学软件SPSS相结合的方法对土壤水分的空间变异性进行分析,通过对样地数据插值和趋势面分析可知二次趋势面方程拟合较好,表明样地的土壤水分空间分布变异十分显著,土壤水分顺着坡度方向呈逐渐增加趋势,反映了坡地土壤水分的一般规律。计算结果对水土保持和农田灌溉有重要的指导意义。

| Abstract: | This paper tries to analyze the spatial variability of soil water with MATLA and SPSS, which are the software with great function in data operation and processing. Through the sample data interpolation and trend surface analysis of trends in secondary known better fitting equation, that showed that this kind of spatial distribution of soil moisture variation was very significant. Soil moisture along the direction of the gradient was gradually increasing trend, reflecting the slope of the general rules of so... |
