Abstract: The results of planting experiment with two tree species Alnus ferdinandi-coburgii and Sabina chinensis under the same site and cultivation conditions showed that the average annual growth of the sapling height,basal diameter and crown diameter of Alnus ferdinandi-coburgii was 3.9,2.9 and 6.7 times higher than that of Sabina chinensis respectively. It was also showed by the experiment that Alnus ferdinandi-coburgii had better adaptability to varied site conditions and stronger resistance to adverse conditions than Sabina chinensis. It was recommended that Alnus ferdinandi-coburgii be planted in a larger scale in Yuxi Municipality for its characteristics of quick growth speed,fast greening effect,easy to be grown and simple to be tended after being planted.
