摘　　要：对腾冲县苏江林场于2012年春季在杉木采伐迹地上采用南酸枣、桤木、光皮桦与萌生杉木营造混交林,3年生时进行了调查并分析。结果表明:造林3年后3个树种的幼林保存率均达到92%,南酸枣、桤木、光皮桦阔叶树种的早期生长均表现了较强的速生性,各树种平均树高和胸径依次为南酸枣6.0m和6.5cm,桤木5.8m和6.2cm;光皮桦4.8m和4.4cm。南酸枣更适宜作为腾冲杉木采伐迹地的更新树种,营造速生丰产的工业原料林。A mixed forest which contains Choerospondias axillaris,Alnus,Betula luminifera and the coppice of Chinese fir was built on the cutover land of Chinese fir in Sujiang Forestry Centre in the spring of 2012.The article conducts an investigation and analysis of the mixed forest after years.The results indicate that three years after the afforestation,the preservation rate of the three species＇ young forest reaches 92%and the early growth of the Choerospondias axillaris,Alnus and Betula luminifera shows stronger fast-growing.The average height and DBH of Choerospondias axillaris is 6.0mand 6.5cm.That of Alnus 5.8mand 6.2cm and that of Betula luminifera is 4.8mand 4.4cm.Therefore,Choerospondias axillaris is more suitable being the regenerated species on the Chinese fir cutover land in Tengchong,which aims to create fast-growing and high yield industrial raw material forest.
