耕地质量预警的研究与应用研究进展

Study and Application Research Progress of Cultivated Land Quality Early-Warning System

为了进一步研究和探索耕地质量预警,从土壤质量和土地利用变化、预警理论方法和指标体系、预警模型、基于WebGIS平台的预警应用等角度分析和总结了国内外近20年耕地预警的研究进展,提出了要从土壤肥力与质量、高标准基本农田、遥感、耕地污染4个方面进行耕地质量的综合预警。

In order to further research and explore cultivated land quality early-warning, this paper analyzed and summarized research progress of Cultivated Land Early-Warning nearly 20 years at home and abroad from soil quality and land use change, early-warning theories and index system, early-warning model and application of cultivated hind early-warning based on WebGIS. Then the comprehensive early-warning for cultivated land quality is put forward from soil fertility and quality, high standard farmland, remote sensing and farmland contamination.
