在保山市隆阳区国有林场采用25个种源、3种改造模式对以云南松、华山松为主的针叶纯林进行改造，并以不处理模式作为对照。试验结果表明，各保存种源在树高、地径、冠幅生长以及保存率指标上均达到极显著性差异（ P＜0.01）；在16个保存种源中，五角枫的树高、地径、冠幅生长情况最好，但保存率偏低；其次是马蹄荷、长梗润楠、多花含笑、光皮桦，保存情况均优于五角枫。中缅木莲在树高、地径、冠幅的生长以及保存情况上最差；不同改造模式间针叶树的树高生长和胸径生长均达到极显著性差异（P＜0.01），带状改造模式效果最好，间伐改造模式次之，直接改造和不处理模式效果最差。

Transformation test has been conducted in pure forest of Yunnan pine and pinus armandi at Baoshan state-owned forest farm by using 25 kinds of sources , three kinds of transformation mode.The test results compared with control which showed that the difference of preservation provenances in tree height, diameter, crown growth and preservation rate were significant ( P <0.01); in 16 preservation provenance, performance of Acer mono tree was the best in height , ground diameter, crown, but preser-vation rate was low;followed by horseshoe Netherlands , long-stemmed Machilus, floribunda, luminifera, but save rate were better than Acer mono.The performance of Magnolia tree in height , diameter , crown growth and the preservation rate were the worst;Under different transformation modes , the differences of conifer tree in height and diameter growth were highly significant (P <0.01), the effects of ribbon trans-formation mode was the best , followed by thinning transformation model , the direct transformation mode and non-processing model were the worst.
