本文应用多元分析方法,对海南岛的气候、土地、水利和生物等自然资源因素的相互作用关系进行综合评价、分类和排序,为农亚区划及农业生产合理布局提供科学依据.
Taking Hainan Island as an example, using the software package including principal components analysis, factor analysis and cluster analysis, and a M-350 S computer, the data about agricutural natural resources 93 of geographical units of the island over the past 30 years are processed. The integrated evaluation and regionalization of agricultural natural resources of the island was carried on in three steps: 1) the integrated evaluation and regionalization of climate esources; 2) the integrated evaluation and regionalization of climate, water and soil resources; 3) the integrated evaluation and regionalizafion of climate, water, soil and crops resources. Three Characteristics of applying this approach are: 1) the qualitative and quantitative analysis and systematic synthesis are combined, the overlapping method is replaced by the systematic synthesis; 2) the monomial and integrated regionalization are combined; and 3) the manual operation is replaced by the computer operation,
