赤红壤贮水量变化过程的聚类分析研究

Cluster Analysis of Process of Change in Water-holding Content of latored Soils

根据长期定位观测资料．用多元数据分析的有序样本分类中的最优分割法对南亚热带地带性土壤──赤红壤的土壤水分贮水量的变化过程进行聚类分析并进行土壤水分的季节划分，结果表明．赤红壤贮水量最高贮量出现在3～7月，最低出现在1～2月和10～12月，而8～9月为干湿交替变化的过渡阶段．

Based on the long term observational data. optimal cutting method for ordered sample classification of multielement data analysis was used for cluster analysis and season division of process of change in water-holding content of latored soils Results show that, the maximum water-holding content exists from March to July, the minimum one from october to February next year, and August to September is a period of transition between dry and wet.
