Research on Permanent Basic Farmland Monitoring System and Zoning Regulation Method
Based on the traditional permanent basic farmland monitoring system,the paper explored and constructed a normalized and quantified"trinity"monitoring system,including 10 quantity indices,11 quality indices,and 6 ecological security indices.Also,the paper established a dynamic and digital basis and principle for identifying different zones of permanent basic farmland.Combined with functional types,permanent basic farmland was divided into 9 supervision areas with risk levels of high,medium,and low.In addition,targeted and differentiated zoning supervision strategies were proposed.
