摘　　要：对玉溪市大山和大栗园川滇桤木和藏柏人工林分进行生长量调查.应用单因素方差分析和LSD检验法进行比较,结果表明两者差异显著,川滇桤木生长量明显高于藏柏.说明川滇桤木在干旱瘠薄、土壤地力较差的立地条件下比藏柏生长好,具有生长迅速、适应性强的特点.The growth volumes of Alnus sp. and Cupressus torulosa plantation stand have been surveyed in Dashan and Daliyuan of Yuxi city, and single factor variance and LSD test have been applied to compare the result. The final result reveals that there are striking differences between them, and the growth volume of Alnus sp is apparently higher than that of Cupressus torulosa in detail. This illustrates that Alnus sp. which has the characters of fast growth and strong adaptation can grow better than Cupressus torulosa under the condition of dry ＆ barren soil and poor site situation.
