空间插值方法在土壤养分评价中的应用——以滩小关水源地评价为例

The Spatial Interpolation Method in the Soil Nutrient Appraisal Application——Take the Tan Xiao Guan Water Source Appraisal as an Example

以地理信息系统技术和传统技术相结合,定性与定量相结合,用系统论和对比分析的方法调查,分析,评价了滩小关水源地土壤养分质量状况,并针对其中存在的问题提出了建议。其中,利用GPS快速准确地测到带有坐标记录的采样点,利用ArcviewGIS对采样点进行空间插值获取土壤养分等级空间分布图并进行了科学的分析。结果表明:研究区土壤养分含量缺乏,尤其氮磷养分不足,有机质含量不高。

This research had been investigated,analyzed and appraised the Tan Xiao Guan water source soil nutrient quality condition through combinating the geographic information system technology and the traditional technology,the quantitative and qualitative methods,the system theory and the contrast analysis methods,and had been aimed at existence the question to put forward the proposal.The GPS and ArcviewGIS were used to carry on the spatial interpolation of soil nutrient and analysis.The results indicated that the nutrient contents were lower in soils in this area,especially the nitrogen,phosphorus and organic matter.
