摘要
立地类型划分的科学与否是营造混交林成败的关键.应用模糊-C均值(FCM)算法改变了传统的立地类型组通过人为给定阈值的划分方式.本研究中,FCM依据外业调查数据对样地进行分类,将其划分为4个簇即4个立地类型组:阳坡低海拔立地类型组、阳坡高海拔立地类型组、阴坡高海拔立地类型组、阴坡低海拔立地类型组.
Whether classification of site type is scientific or not is the key for plantation of mixed forests. Application of Fuzzy C- means algorithm to site type changes traditional classification of site type by setting threshold manually. According to site investigation, these data are classified into four 'clusters named after sunny side exposure lower altitude site type group, sunny side exposure higher altitude site type group, shade side exposure higher altitude site type group, shade side lower altitude site type group.
