摘要
为解决目前南方林区人工林针叶化引起的系列生态问题,挖掘本地乡土树种,发展阔叶树种造林,通过营造不同混交模式的酸枣杉木混交林,进行不同混交模式酸枣杉木混交林林分生长效应的比较研究,结果表明:不同混交比例的酸枣杉木混交林群落特征和林分生长存在较大差异,不同林分蓄积量大小排序为:酸枣纯林>酸枣×杉木(1∶3)混交林>酸枣×杉木(1∶2)混交林>酸枣×杉木(1∶1)混交林>杉木纯林,其中杉木×酸枣(3∶1)混交林是种间关系较为协调并具较高生产力的混交模式,值得南方林区大力推广。
The community character and growth of different mixed forests of Cunninghamia lanceolata and Choerospondias axillaries are investigated.The results show that there are significant differences during the community character and growth of different mixed forests.The stand volumes are in sequence of pure forest of C.axillaries > mixed forest of 3 C.lanceolata with 1 C.axillaries> mixed forest of 2 C.lanceolata with 1 C.axillaries > mixed forest of 1 C.lanceolata with 1 C.axillaries > Chinese fir pure forest.The mixed forest of 3 C.lanceolata with 1 C.axillaries is a practicable mixed model in South China.
