摘要
以上海市临港新城土壤(20cm～50cm)中有机质为研究对象,利用地统计与GIS技术相结合的方法研究了该地区土壤中有机质的空间分布特征。采取普通克里金(Ordinary Kriging)插值法绘制了土壤有机质的空间分布图。土壤有机质呈现中等程度空间自相关,含量由西向东逐渐增加,沿海周边又有所下降。
Taking the organic matter in the soil （20cm^50cm） of Shanghai Lin＇gang New Town as the study object,this paper uses statistical method and GIS technology method to study the spatial distribution characteristics of organic matter in the soil in the area.Ordinary Kriging interpolation method is used to draw the spatial distribution of soil organic matter.The soil organic matter shows the moderate spatial auto-correlation and its content gradually increases from West to East,and that around the coast also declines.
