摘要
通过理论研究和实证分析,研究农用地分等国家级汇总中农用地自然质量等别平衡转换的方法,为国家级的农用地分等成果汇总奠定基础。在全国的农用地分等汇总中,用标准粮单产及相应的转换函数,实现农用地自然质量等别的平衡转换。研究结果表明,全国的标准粮产量分别与省级和国家级的自然质量等指数呈显著相关,可以通过这一衔接手段完成农用地自然质量等别的国家级汇总。
Based on theoretical research and empirical analysis, the method for equilibrium conversion of the farmland natural quality grade at the national farmland grading collection level was studied. It laid foundation for national farmland grading results collection. The natural quality grades of farmland could be conversed equally by using standard grain yield and relevant transfer function. The results showed that the standard grain yield of the whole country was significantly correlated with provincial and national natural quality index respectively, and the farmland natural quality grading collection at national level can be completed by this cohesive device.
