摘要
本文根据田间土壤采样数据,以“精确农业”为指导思想,以地统计学为基本原理,以GIS软件ArcView为工具,生成了土壤养分空间分布图,这是了解土壤养分空间变异性的重要手段,从而为以后的精确施肥奠定了基础。
The paper presents a research method for developing spatial distribution map of soil nutrients based on a GIS software, ArcView. According to the field sampling data and localities measured by GPS a spatial distribution map of soil nutrients and fe^ization information was set up. This research is also a methodological contribution for precision agriculture and provides a ground for precise application of fertilizers based on the understanding of nutrients variation.
