摘要:

构建高效、规范化的空间插值方法,快速、准确获取县域乃至全国的耕地质量指标分布图,是建设耕地质量大数据平台、服务宏观决策亟待解决的重要问题。本研究通过文献梳理和研究述评,归纳了目前空间插值方法的概念、流程,明晰了其精度影响因素以及在耕地质量监测评价中的应用现状。结论:为满足耕地质量大数据平台建设的实际应用需求,未来需从4个方向开展空间插值方法的深入研究,包括分区域空间插值、考虑地理阻隔的空间插值、基于辅助变量的空间插值和空间插值的功能模块设计。研究成果可为耕地质量数据标准化处理提供方法参考。

Abstract:

Constructing an efficient and standardized spatial interpolation method is an important issue for building the big data platform for cultivated land quality and serving macroscopic decision-making, and is conducive to quickly and accurately obtain the distribution map of cultivated land quality indicators of counties and even the whole country. Through literature and research review, this study summarized the current concept and process of spatial interpolation method, and clarified its precision influencing factors and application status in monitoring and evaluation of cultivated land quality. Combined with the actual application requirements of the big data platform for cultivated land quality, four in-depth research directions were put forward, including regional interpolation, geographic barriers interpolation, auxiliary variables interpolation, and module design of interpolation. The research results could provide method reference for the standardized processing of cultivated land quality data.

Key words: cultivated land quality, soil, spatial variability, interpolation, data processing
