| 摘 要： | 为了探讨定量化分析手段在全国耕作制度区划中的应用方法，通过对耕作制度区划指标逐项探讨、对现有的耕作制度分区进行了调整试验的方式，研究了全国耕作制度分区的指标体系，以及“区划指标数据库建立”、“气候指标值提取”、“地形单元提取”、“低级单元聚类”等定量化方法在耕作制度分区中的应用。结果表明：（1）明确的多级指标体系是定量化区划的关键；（2）耕作制度区划中使用定量化方法的技术框架是“自上而下”与“自下而上”相结合，在不同层级上采用不同的定量化分析方法；（3）在专家集成定性分析的框架下，定量化方法可以有效地提高耕作制区划的准确性与合理性。 |

| Abstract: | To discuss methodology of regionalization of farming system supported by quantitative analysis. This paper studies the index system of regionalization of farming system, and methodology of database establishment, climate index value extraction, landform unit extraction, low-level regions merging in regionalization of farming system. These studies show that: an explicit multi-level index system is the key for quantitative regionalization. A technical framework for quantitative regionalization is combined by bottom-up and top-down, which uses different methods in different levels. Quantitative analysis in a qualitative frame could improve the rationality and accuracy in regionalization of farming system. |
