基于Kriging插值的高效耕地质量监测点布设方式研究——以建瓯市为例

耕地质量是关系国计民生的基础,对耕地质量实行监测是国土资源管理的现实需求,因此高效、可行的监测样点布设对耕地质量等级监测显得尤为重要。本文通过单纯格网法、简单随机抽样法和基于Kriging插值法对建瓯市耕地质量等级监测进行高效样点布设研究。结果表明,基于Kriging插值的布样方法精度最高,且基于Kriging插值方法布设的67个监测样点能够满足监测的精度要求,说明基于Kriging插值方法对建瓯市耕地等级质量监测进行布点是一种高效且可行的方法。

Study on the Layout of Efficient Arable Land Quality Monitoring Samples based on Kriging Interpolation Method-Case Study in Jian＇ou County

The quality of arable land is the basis of the people＇s livelihood.The implementation of monitoring on the quality of arable land is the practical needs of the land and resources management.Efficient and feasible laying of monitoring samples on arable land quality levels is particularly important.In this paper,the simple grid method,random sampling method and Kriging interpolation method were used for level monitoring of the arable land quality of Jian＇ou City.The results show that,Kriging interpolation method has the highest accuracy and 67 monitoring samples can meet the accuracy requirements based on this method.Therefore,the layout of monitoring samples based on the Kriging interpolation is efficient and feasible method on Jian＇ou arable land＇s level quality.
