摘  要:
利用GPS和GIS技术,对位于雷州半岛的广东省幸福农场的土壤物理参数进行了调查,得到0~30cm深度范围内土壤的圆锥指数、含水率和密度分布图,并进行了3种耕作方式对土壤圆锥指数影响的对比。通过分析得出,土壤含水率不仅影响作物的生长,而且在一定程度上影响土壤的其他基本参数。

摘  要:
The soil physics parameters of latosol was investigated based on GPS and GIS technology in Xingfu Farm, Leizhou Peninsula, South China, which belongs to southern dry land agriculture area. The distributing maps of cone index, moisture content and bulk density of soil were figured by using the interpolation method of Kriging in Surfer software. The spatial variability of soil parameters was analyzed. The investigation result showed that the soil moisture content, bulk density and cone index had the spatial correlation.
