摘要: 本文应用R型主因子法作农业地域类型形成的自然地理要素分析和综合指数构造,在聚类分析基础上划分综合农业地域类型。

Abstract: All the studies of areal types of agriculture depend largely upon the qualitative investigation in terms of geographical princeples, which tends to wards subjective appraisal of rational distribution of agriculture. Taking Lingxian county, northeast Shandong Province, which is located in the Huangfan Plain as a study region,the thesis lays emphasis on the quantification for elements of physical geography affecting the agricutural diversity as well as the clustering method for classification. By combining mathematical simulation with the conventional geographical analysis, this approach shows superiorities in improving objectivity and precision in the classification of areal types of agriculture with the aid of electronic computers. Throngh comprehensive classification, Lingxian county is divided into 5 comprehensive areal types of agriculture.
