关于造林立地分类,我国目前普遍采用地形-土壤主导因子定性分类方法。由于电子计算机技术的发展,我国已开始应用数量化方法。这一方法的应用,无疑使造林立地质量评价的水平有了一个新的提高。由于“数量分类学”的发展,国外有人将聚类分析方法应用于造林立地分类中(D.Ra-dloff and D.Betters 1978),国内亦有人对此进行过研究。 About afforestation site classification, at present, we generally use topographic-soil dominant factor qualitative classification method. Due to the development of computer technology, our country has begun to apply quantitative methods. The application of this method will undoubtedly bring about a new improvement in the quality of afforested sites. Due to the development of “quantitative taxonomy”, some people abroad have applied clustering analysis to afforestation classification (D. Ra-dloff and D. Betters 1978). Some people in China have also studied this.
