摘  要：
针对曹娥江上中游不同林地类型开展了针叶林阔叶化改造营建技术研究,结果表明:(1)林下目标阔叶树种稀少的马尾松疏林,郁闭度在0.2以下,采用疏林补植营建技术,适合阔叶林树种有木荷、桂花、杜英、香樟、冬青、红运玉兰、白玉兰、无患子、银杏、枫香、乳源木莲、深山含笑等;(2)具有更新层的马尾松纯林、针阔叶混交林,郁闭度0.5以上,或以自然整枝强烈的阔叶树为主的针阔混交林、阔叶混交林,郁闭度0.9以上,宜采用疏伐封育措施,固定标准样地(20m×30m)阔叶林蓄积量由伐前的6.148 1m3提高到伐后3年的7.384 6m3,蓄积量百分率由伐前的25.7%提高到伐后3年的30.93%。

摘  要：
Technology of broadleaved-oriented transformation for coniferous forest were studied aimed by different forest types in Caoe River.Result shows that:(1)Replanting techniques for wide-row planting were adopted in wide planting of Pinus massoniana with rare broad-leaved tree(crown density<0.2);using silviculture technology of replanting in sparse wood land,the optimal broad-leaved species are Schima superba,Osmanthus fragrans,Elaeocarpus decipiens,Cinnamomum camphora,Ilex chinensis,Magnolia denudata,Michelia alba,Sapindus mukorossi,Ginkgo biloba,Liquidambar formosana,Manglietia yuyuanensis & Michelia maudiae;(2)The techniques of thinning &enclosed measure should be adopted in pure forest of Pinus massoniana and coniferous and broad-leaved mixed forest with the regenerated layers(crown density>0.5)or coniferous and broad-leaved mixed forest and mixed broadleaved forest that are mainly broad-leaved tree(crown density>0.9).Volume of broadleaved forest in the fixed standard plot(20m×30m)are from 6.148 1m3 to 7.384 6m3 three years after cutting;volume percentage are from 25.7%to 30.93%.
